API integration

Direct integration

Direct integration allows you to accept split payments using your own payment page. At the same time, the integration allows making payments using payment cards and alternative payment methods.

Interaction format:

info

Note: the use of direct integration when collecting card data on the merchant side requires PCI DSS certification. Alternatively, you can use our tokenization widget by implementing it on your site.

If using direct integration, if payment data is collected on your end, make sure that it is properly validated on your page, including:

  • Card expiration date validation.

  • Checking the card number according to the (Luhn algorithm).

  • The entered CVV/CVC contains only numbers.

Features of using direct integration:

  1. The payment page must use the HTTPS protocol.
  2. Customer details must be persistent and unique.
  3. Use the HTTP POST method.

splitArray[SplitPayment]Split payment properties

Depending on whether the request is full card data or a token, you need to pass the following parameters:

  • Using full card data: cc_number, exp_month, exp_year, card_cvv.
  • Using tokens: cc_token.
info

In addition to supporting payments with tokens received after card payments, we also support tokens generated during the first payment via Apple Pay or Google Pay. These tokens should be passed in the cc_token parameter

For example:

"cc_token":"rcr:ODJkZjBhNmY2OTMyNDJlN2wjMjFjfTQzOXU3ZDFhYzI6cWJmWHFmMHlzM3hYaXJMWEZv" (token after an Apple Pay or Google Pay payment)
or
"cc_token": "ODJkZjBhNmY2OTMyND7sSjdD0S8TQzOXU3ZDFhYzI6cWJmWHFmMHlz M3hYaXJMWEZv" (token after a card payment).

Moreover, the split payment must additionally contain specific parameters:

Next steps

To test the payment process:

Find more details in the integration checklist.

After completing the test to go live, you need:

  1. Create a live project in the merchant portal.
  2. With direct integration: pass PCI DSS certification (if you intend to work with card data of payers on your side) or implement a tokenization widget (possibility of making direct payments without using card data).
  3. After receiving information from our Compliance team about the completion of the settings for the project, make changes to the authentication data using the data of the live project.
  4. You are ready to receive payments from your customers.
