Welcome to Crypto.com Pay for Business! Here you can find out how you can adopt the best way to accept cryptocurrency payments.

Crypto.com Pay for Business is a feature of Crypto.com Pay, which utilises Crypto.org Chain as a high performing native blockchain solution. This enables the transaction flows between crypto users and merchants seamless, cost-efficient and secure.

You can read more about Crypto.org Chain here.

Accepting Payments

Payment Methods

Crypto.com Pay for Business supports payments using Crypto.com App and other cryptocurrency wallets.

A Crypto.com App user can simply use the Crypto.com App (available on iOS and Android) to scan the QR code, select their preferred payment cryptocurrency and complete the transaction. Please refer to this FAQ article for the screen examples.

Customers can also pay with other cryptocurrency wallets other than Crypto.com App, such as Crypto.com DeFi Wallet, MetaMask, WalletConnect or Ledger, etc to pay. Please note that the customers will have to bear the network fees when they choose to pay using methods other than Crypto.com App.

Checkout Payment Flow

Please check out this video and this FAQ article for the payment experience.

When creating payments for your customers to pay, you can specify the payment amount (your products' listed price) in any supported fiat currencies (e.g. 1,000 USD) / supported cryptocurrencies (e.g., 0.03 ETH). The Crypto.com Pay payment page will provide your customers with different cryptocurrency payment options. It will also determine the amount required in customer selected cryptocurrency (e.g. 250 CRO).

Once paid, the payment is captured on the merchant's end, the cryptocurrency will then be converted and credited into your wallet balance. You can select the merchant default currency from one of the Payout currencies we support.

Subscription Flow

The Crypto.com Pay subscription payment page will guide your customers to select the cryptocurrency to pay and approve the subscription. Once it is approved, payment of the first billing period will be collected right away. In subsequent billing periods, payments will be automatically created and collected.

The subscription payment amounts can be specified in any supported fiat currencies (e.g. 1,000 USD) / supported cryptocurrencies (e.g., 0.03 ETH). Once the payment of each period is captured, the cryptocurrency will be converted and credited into your wallet balance.

Both you and your customers can cancel the subscription anytime.

Subscription is only available to customers using Crypto.com App.

Payment Currencies

Crypto.com Pay for Business currently accepts the following cryptocurrencies:

• Cronos (CRO)
• Bitcoin (BTC)
• Ethereum (ETH)
• Dogecoin (DOGE)
• Stable Coins (TUSD, USDC)
• Other tokens supported by Crypto.com App and Crypto.com DeFi Swap

Please refer to this FAQ article for the full list of cryptocurrencies supported.

For information on available payout currencies for merchants, please see Payout.

Fees

Crypto.com Pay for Business has no transaction fee. For each payment from customers, merchants are guaranteed to receive the fiat currency amount they specified. The amount will be credited into the balance of the merchant account and can be withdrawn anytime.

When merchants request payout, a payout fee is applied. Please see Payout for more information.

Cashback

The cashback incentives are granted to the customers as Crypto.com Pay Rewards when they choose to pay in CRO. Crypto.com Pay Rewards are always distributed back to Crypto.com App. Merchants are not entitled to cashback incentives at the moment.

Once you logged into the Merchant Dashboard, you can see the Pay Rewards percentage that your customers can earn.

For information on Crypto.com Pay Rewards, please visit this FAQ article.

Refund

Merchants can refund all payments received either partially or in full.

For customers who pay using Crypto.com App, the refund will be sent back to their App account automatically. A preferred refund currency setting is available in App so that customers can select the cryptocurrency they want to receive for refunds.

For customers who pay using other cryptocurrency wallets, the payment page requires them to input their email addresses when they pay. When a refund is issued, a refund claim link and instruction will be sent to the email address provided for the customer to claim the refund. Subject to the refund method selected, a blockchain fee may be deducted from the refund amount.

Unresolved Payments

For customers who pay using other cryptocurrency wallets, the payment can be overpaid or underpaid. This is because there is no payment amount input check, and the cryptocurrency exchange rate could be updated when customers made the payment. The payment can also be late if the funds did not reach the provided wallet address in time.

If the payment is overpaid, the overpaid portion (with blockchain fee deducted) will be rebounded to the customer. On the merchant's end, the payment is still considered to be captured successfully.

If the payment is underpaid or late, the whole payment (with blockchain fee deducted) will be rebounded to the customer.

Similar to refund, a rebound fund claim link and instruction will be sent to the customer email address provided, so they can claim the rebound fund.

If the payment is sent using a cryptocurrency or network not supported by Crypto.com Pay, the funds will not be refunded or rebounded.

Merchant can navigate to Merchant Dashboard -> Payments -> Unresolved page to view these transactions. The claim links of the rebound fund can be found in the detailed view of each unresolved transaction.

Underpayment Threshold

To improve the user experience of on-chain payments and reduce the unnecessary network fees, merchants can decide a threshold of accepting payments from other cryptocurrency wallets even when those are underpaid.

The underpayment threshold can be set up in an absolute or relative (percentage) manner. Payments will be captured when they are within any of these two thresholds. Customers will not see these thresholds.

When a payment is underpaid and captured, the amount will be credited to the merchant account on a pro-rata basis. For example, if a customer paid 98 USDC for a payment with the amount of 100 USD, and it is within the threshold, then 98 USD will be credited to the merchant account.

Merchant can navigate to Merchant Dashboard -> Settings -> Payment page -> Underpayment Threshold to set up. This option is only enabled when the other cryptocurrency wallets payment option is enabled.

Payments paid using Crypto.com App will not be underpaid.

Merchant Acquirers

We welcome acquirers to help Crypto.com Pay onboard more merchants. Please contact [email protected] if you are interested.

Acquirers are required to provide simple business information about the sub-merchants under their account, including an ID.

When creating payments, the ID of the sub-merchants is required. The same field can be retrieved in payment and refund APIs.

Integration Guides

Checkout - Button SDK

Generate the Crypto.com Pay Button and embedded it on your website. Once the button is clicked, there will be a popup for customers to complete payment.

You will be able to see this on your checkout page:

You can always take a look at the Crypto.com Shop and see what it is like in the real world.

Get started by picking one of the following integration approaches, as simple as that!

Approach 1: Frontend and Backend Integration

Step 1: Register Crypto.com Pay Developer Access

Sign up for a Crypto.com Pay account, if you don't already have one.

Once you have access to the Crypto.com Pay Merchant Dashboard, You will be able to generate a secret key and publishable key pair. You should use the publishable key in the Crypto.com Pay SDK and the secret key when you directly interact with the Crypto.com Pay API.

Step 2: Add the Crypto.com Pay SDK Script

Add the script

<body>
  <script src="https://js.crypto.com/sdk?publishable-key=YOUR_PUBLISHABLE_KEY_PLACEHOLDER"></script>
</body>

Add the following script to your web page. Replace the YOUR_PUBLISHABLE_KEY_PLACEHOLDER with your Publishable Key.

Step 3: Create a Payment

Create payment

curl https://pay.crypto.com/api/payments \
  -u YOUR_SECRET_KEY_PLACEHOLDER: \
  -d amount=10000 \
  -d currency=USD \
  -d description="Product Name"

On server side, obtain a payment ID by creating a payment. Replace the YOUR_SECRET_KEY_PLACEHOLDER with your Secret Key. If you use curl, please note that a colon is needed after the Secret Key to prevent it from asking you for a password. A new payment is always pending to be captured. See Create a Payment for reference and the list of arguments you can pass in.

Response

{
  // Showing seclected fields only
  "id": "PAYMENT_UNIQUE_ID",
  "amount": 10000,
  "currency": "USD",
  "description": "Product Name",
  "status": "pending"
}

Step 4: Render the Crypto.com Pay Button

Render the button

<body>
  <script
    src="https://js.crypto.com/sdk?publishable-key=YOUR_PUBLISHABLE_KEY_PLACEHOLDER">
  </script>

  <script>
    var paymentId = document.querySelector('#pay-button').dataset.paymentId

    cryptopay.Button({
      createPayment: function(actions) {
        return actions.payment.fetch(paymentId)
      },
      onApprove: function(data, actions) {
        // Optional: add logic such as browser redirection or check data object content
      },
      defaultLang: 'en-US' // Optional: default language for payment page
    }).render("#pay-button")
  </script>

  <div id="pay-button" data-payment-id="PAYMENT_UNIQUE_ID"></div>
</body>

Add a container element on your page and render the Crypto.com Pay button in it. Also pass the Payment ID created in Step 3 into this container (attribute is data-payment-id).

Then implement the createPayment function. This function will be invoked when the customer clicks on the Crypto.com Pay button. Since you already have a Payment ID from Step 3, you just have to provide it and the SDK will not create another new payment.

Then implement the onApprove function. You should add logic here to notify your server side which perform Step 5. Once Crypto.com Pay captures the payment, the checkout window will indicate that the payment has been captured and the onApprove function will be called.

Step 5: Verify payment status

Retrieve the payment

curl https://pay.crypto.com/api/payments/PAYMENT_UNIQUE_ID \
  -u YOUR_SECRET_KEY_PLACEHOLDER: \

On server side, retrieve the payment and check whether the payment status is succeeded. See all the statuses here.

Approach 2: Frontend Only Integration

Step 1: Register Crypto.com Pay Developer Access

Sign up for a Crypto.com Pay account, if you don't already have one.

Once you have access to the Crypto.com Pay Merchant Dashboard, You will be able to generate a secret key and publishable key pair. You should be using the publishable key in the Crypto.com Pay SDK and the secret key when you directly interact with the Crypto.com Pay API .

Step 2: Add the Crypto.com Pay SDK Script

Add the script

<body>
  <script src="https://js.crypto.com/sdk?publishable-key=YOUR_PUBLISHABLE_KEY_PLACEHOLDER"></script>

Step 3: Render the Crypto.com Pay Button

Render the button

<body>
  <script
    src="https://js.crypto.com/sdk?publishable-key=YOUR_PUBLISHABLE_KEY_PLACEHOLDER">
  </script>

  <script>
    cryptopay.Button({
      createPayment: function(actions) {
        return actions.payment.create({
          currency: 'USD',
          amount: 100,
          description : 'Product Name',
          order_id: 'sample-order-id',
          metadata: {
            size: 'XL',
            color: 'black'
          }
        });
      },
      onApprove: function (data, actions) {
        // Optional: add logic such as browser redirection or check data object content
      },
      defaultLang: 'en-US' // Optional: default language for payment page
    }).render("#pay-button")
  </script>

  <div id="pay-button"></div>
</body>

Add a container element on your page and render the Crypto.com Pay button in it.

Then implement the createPayment function. This function will be invoked when the customer clicks on the Crypto.com Pay button. The action.payment.create function creates a new pending payment in the Crypto.com Pay server by providing details of the purchase as arguments. See Create a payment for reference and the list of arguments you can pass in.

Then implement the onApprove function. Once Crypto.com Pay captures the payment, the checkout window will indicate that the payment has been captured and the onApprove function will be called.

Checkout - Page Redirection

If you prefer a solution that has minimal impact to your user interface design, you may use your existing checkout interface, and redirect to Crypto.com payment page when customers submit your checkout form. Once the payment is made, the payment page will redirect back to your store to finish your order flow.

Step 1: Register Crypto.com Pay Developer Access

Sign up for a Crypto.com Pay account, if you don't already have one.

Once you have access to the Crypto.com Pay Merchant Dashboard, You will be able to generate a secret key and publishable key pair. You should use the secret key when you directly interact with the Crypto.com Pay API.

Step 6: Render the Crypto.com Pay Button

Render the button

<body>
  <script
    src="https://js.crypto.com/sdk?publishable-key=YOUR_PUBLISHABLE_KEY_PLACEHOLDER">
  </script>

  <script>
    var subscriptionId = document.querySelector('#pay-button').dataset.subscriptionId;

      createSubscription: function(actions) {
        return actions.subscription.fetch(subscriptionId);
      },
      onApprove: function(data, actions) {
        // Optional: add logic such as browser redirection or check data object content
      },
      defaultLang: 'en-US' // Optional: default language for payment page
    }).render("#pay-button")
  </script>

  <div id="pay-button" data-subscription-id="SUBSCRIPTION_UNIQUE_ID"></div>
</body>

Add a container element on your page and render the Crypto.com Pay button in it. Also pass the Subscription ID created in Step 5 into this container (attribute is data-subscription-id).

Then implement the createSubscription function. This function will be invoked when the customer clicks on the Crypto.com Pay button. Since you already have a Subscription ID from Step 3, you just have to provide it and the SDK will not create another new payment.

Then implement the onApprove function. You should add logic here to show the success message. Once Crypto.com Pay got your customer's payment authorization on the subscription, the onApprove function will be called.

Step 7: Verify subscription status

Retrieve the subscription

curl https://pay.crypto.com/api/subscriptions/SUBSCRIPTION_UNIQUE_ID \
  -u YOUR_SECRET_KEY_PLACEHOLDER:

On server side of your return_url page, retrieve the subscription and check whether the subscription status is active. See all the statuses here.

Step 8: Monitor events

After the subscription turned into active, it will collect payment for the first billing period right away. Invoice objects and its associated payment objects will be created automatically for each billing period. Cryptocurrency payment will be collect from customer's Crypto.com App automatically based on the currency setting they used when they approved the subscription.

You should monitor invoice.paid and invoice.payment_attempt_failed events for your subscriptions. Please refer to Webhooks for more details.

Subscription - Page Redirection

If you prefer a solution that has minimal impact to your user interface design, you may use your existing checkout interface, and redirect to Crypto.com subscription payment page when customers submit your checkout form. Once the subscription approval is made, the subscription payment page will redirect back to your store to finish your order flow.

Step 1: Register Crypto.com Pay Developer Access

Sign up for a Crypto.com Pay account, if you don't already have one.

Once you have access to the Crypto.com Pay Merchant Dashboard, You will be able to generate a secret key and publishable key pair. You should use the publishable key in the Crypto.com Pay SDK and the secret key when you directly interact with the Crypto.com Pay API.

Step 2: Create a Product and Pricing Plan

Create product and pricing plan

curl https://pay.crypto.com/api/products \
  -u YOUR_SECRET_KEY_PLACEHOLDER: \

  "ref_id": "6ded84e75449",
  "name": "John Doe",
  "created_at": 1627917897,
  "updated_at": 1627917897
}

Step 4: Create a Subscription

Create subscription

curl https://pay.crypto.com/api/subscriptions \
  -u sk_test_7ETNLmgFVsmmdiEhfqwjHPeJ: \
  -H "Content-Type: application/json" \
  -d '{
    "customer_id": "8e384561-d781-4868-9b66-3fb2d7a83ba5",
    "return_url": "http://YOUR_WEBSITE.com/orders/123/complete",
    "billing_cycle_anchor": 1625943925,
    "interval": "month",
    "metadata": {
      "ref_id": "34196851011b"
    },
    "items": [
      {
        "plan_id": "2506cad4-fed6-49c0-98f5-34b0bedd6891",
        "quantity": 1
      }
    ]
  }'

With customer ID and pricing plan ID, now you can create a subscription object. You also need to provide a billing_cycle_anchor which is the starting time of your billing cycle. See Create a Subscription section for the schema of subscription object that you should pass in.

It is a must for this flow to provide return_url when creating subscription. The subscription returned will contain a subscription_url for the next step.

Response

{
  "id": "SUBSCRIPTION_UNIQUE_ID",
  "created_at": 1625943925,
  "currency": "USD",
  "amount": 1000,
  "current_period_end": 1628622325,
  "current_period_start": 1625943925,
  "auto_end_at": null,
  "ended_at": null,
  "cancelled_at": null,
  "interval": "month",
  "interval_count": 1,
  "live_mode": true,
  "metadata": {
    "ref_id": "34196851011b"
  },
  "note": null,
  "recipient": "Crypto.com Shop",
  "reference": null,
  "return_url": "http://YOUR_WEBSITE.com/orders/123/complete",
  "subscription_url": "https://js.crypto.com/subscription?publishableKey=XXXsdkMeta=YYY",
  "status": "pending",
  "updated_at": 1625943925
}

Step 5: Redirect to payment page

After creating the subscription object, you will need to redirect customers to subscription_url to finish the payment authorization. After the payment is authorized, the subscription will become active. The payment page will then redirect customers back to return_url (or cancel_url if there is any issue).

Step 6: Verify subscription status

Retrieve the subscription

curl https://pay.crypto.com/api/subscriptions/SUBSCRIPTION_UNIQUE_ID \
  -u YOUR_SECRET_KEY_PLACEHOLDER:

On server side of your return_url page, retrieve the subscription and check whether the subscription status is active. See all the statuses here.

Step 7: Monitor events

After the subscription turned into active, it will collect payment for the first billing period right away. Invoice objects and its associated payment objects will be created automatically for each billing period. Cryptocurrency payment will be collect from customer's Crypto.com App automatically based on the currency setting they used when they approved the subscription.

You should monitor invoice.paid and invoice.payment_attempt_failed events for your subscriptions. Please refer to Webhooks for more details.

Mobile Integration

You can follow the page redirection guide above to integrate Crypto.com Pay in your mobile App.

Instead of redirecting from your website to the payment page, you will need to open a WebView in your App to display the payment page. Once payment becomes succeeded, it will redirect to the page you specified, and therefore you can capture the redirection event and handle order completion.

You may contact [email protected] to get code examples for mobile integrations.

API Reference

Base URL

https://pay.crypto.com/api

The Crypto.com Pay API is organized around REST. Our API has predictable resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

You can use the Crypto.com Pay API in test mode, which does not affect your live data or interact with the payment networks. The API key you use to authenticate the request determines whether the request is live mode or test mode.

The Crypto.com Pay API is still under heavy development and there might be breaking changes. Merchant will be notified in advance if there such change is necessary.

Authentication

Authenticated Request

curl https://pay.crypto.com/api/payments \
  -u sk_test_7ETNLmgFVsmmdiEhfqwjHPeJ:
# The colon prevents curl from asking for a password.

The Crypto.com Pay API uses API keys to authenticate requests. You can view and manage your API keys in the Merchant Dashboard. You should be using your Secret Key.

Test mode secret keys have the prefix sk_test_ and live mode secret keys have the prefix sk_live_.

Your Secret Key carries many privileges, so be sure to keep them secure! Do not share them in publicly accessible areas such as GitHub, client-side code, and so forth.

Authentication to the API is performed via HTTP Basic Auth. Provide your Secret Key as the basic auth username value. You do not need to provide a password.

If you need to authenticate via bearer auth (e.g., for a cross-origin request), use -H "Authorization: Bearer sk_test_7ETNLmgFVsmmdiEhfqwjHPeJ" instead of -u sk_test_7ETNLmgFVsmmdiEhfqwjHPeJ.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.

Errors

The error object

{
  "error": {
    "type": "invalid_request_error",
    "code": "resource_missing",
    "param": "id"
  }
}

Crypto.com Pay API uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a payment failed, etc.). Codes in the 5xx range indicate an error with Crypto.com Pay's servers.

Idempotency

curl https://pay.crypto.com/api/refunds \
  -u sk_test_7ETNLmgFVsmmdiEhfqwjHPeJ: \
  -H "Idempotency-Key: azVNQUJTeVI0MnMyOHk0RQ" \

  -d amount=100 \
  -d reason="requested_by_customer" \
  -d description="Refund for Order#33" \

The Crypto.com Pay API supports idempotency for safely retrying requests without accidentally performing the same operation twice. This is useful when an API call is disrupted in transit and you do not receive a response. For example, if a request to create a refund does not respond due to a network connection error, you can retry the request with the same idempotency key to guarantee that no more than one refund is created.

Idempotent requests are not enabled by default, and it is available for refund API at the moment. To use this for a request, provide an additional Idempotency-Key: <key> header.

An idempotency key is a unique value generated by the client which the server uses to recognize subsequent retries of the same request. It is up to the merchant to define and create their own unique keys.

Webhooks

Webhooks make it easier to integrate with Crypto.com Pay by allowing you to subscribe to a set of events. You can subscribe to the events by going to your Merchant Dashboard and add a new webhook subscription.

When the event is sent to your webhook endpoint, the payload will include the resource object associated. You can refer to Resources for the schema of the objects.

Event Types

Webhook Endpoint

The webhook endpoint must return a 200 response code when it receives a Crypto.com Pay request.

If a 200 response code is not returned, we will retry the same request after 10 seconds until either we get a 200 response code, or we retried for 5 times (6 requests in total including the original one).

Webhook Signature

Crypto.com Pay signs the webhook events that sends to your endpoints. We do so by including a signature in each event’s Pay-Signature header. This allows you to verify that the events were sent by Crypto.com Pay, not by a third party.

Before you can verify signatures, you need to retrieve your endpoint’s Signature Secret from your Merchant Dashboard's Webhooks settings.

Each secret is unique to the endpoint to which it corresponds. If you use the same endpoint for both test and live API keys, note that the secret is different for each one. Additionally, if you use multiple endpoints, you must obtain a secret for each one.

Verifying signatures

The Pay-Signature header contains a timestamp and one or more signatures. The timestamp is prefixed by t=, and each signature is prefixed by a scheme. Schemes start with v1.

Pay-Signature: t=1492774577,v1=5257a869e7ecebeda32affa62cdca3fa51cad7e77a0e56ff536d0ce8e108d8bd

Crypto.com Pay generates signatures using a hash-based message authentication code (HMAC) with SHA-256. To prevent downgrade attacks, you should ignore all schemes that are not v1.

Step 1: Extract the timestamp and signatures from the header

Split the header, using the , character as the separator, to get a list of elements. Then split each element, using the = character as the separator, to get a prefix and value pair.

The value for the prefix t corresponds to the timestamp, and v1 corresponds to the signature(s). You can discard all other elements.

Step 2: Prepare the signed_payload string

You achieve this by concatenating the following in this exact order:

1. The timestamp (as a string)
2. The character .
3. The actual JSON payload (i.e. the request’s body)

1492774577.{"id":"920a4e24-169e-4205-85bd-348c1b834231","object_type":"event","type":"payment.created","created":1492774570,"data":{"object":{"id":"246dce08-019c-4bcb-871d-e8733295e027","amount":1900,"amount_refunded":0,"created":1492774570,"crypto_currency":"CRO","crypto_amount":"107.5","currency":"EUR","customer_id":null,"data_url":"https://pay.crypto.com/sdk/payments/246dce08-019c-4bcb-871d-e8733295e027","payment_url":"https://js.crypto.com/sdk/payments/checkout/set_wallet?publishableKey=XXX&id=246dce08-019c-4bcb-871d-e8733295e027&sdkMeta=YYY","return_url":null,"cancel_url":null,"description":"Test payment","live_mode":true,"metadata":{"customer_name":"Test","customer_email":"[email protected]"},"order_id":"Order ID","recipient":"Test","refunded":false,"status":"pending"}}}

Step 3: Determine the expected signature

Compute an HMAC with the SHA256 hash function. Use the endpoint’s Signature Secret as the key, and use the aforesaid concatenated string as the message.

Step 4: Compare signatures

Compare the signature in the header to the computed signature. If the signatures match, that means the webhook API request is indeed sent from Crypto.com Pay server, as there is no third party supposed to know the Signature Secret.

Additionally, you may compute the difference between the current timestamp and the received timestamp, then decide if the difference is within your tolerance.

To protect against timing attacks, use a constant-time string comparison to compare the expected signature to each of the received signatures.

Troubleshooting

You can navigate to Merchant Dashboard -> Integrations -> Events page in order to view the events sent to your Webhooks and the response from your server.
