Supported workflows

Before you begin

Complete these steps before you send your first Bizum payment through Checkout.com:
  1. Set up a Checkout.com integration in your workspace. Follow the Checkout.com integration setup guide if you don’t have one yet.
  2. Ask Checkout.com support to enable Bizum on your Checkout.com account.
  3. In the Payrails Portal, go to Settings → Integrations, open your Checkout.com integration, select Bizum under Payment methods, and save.
  4. Add Bizum as a payment option in your workflow.

Request fields for Checkout.com

Send these fields in the authorize request, in addition to the standard authorize fields. Required fields must be present for the payment to succeed. Payrails sends Optional fields to the PSP when you include them.

Authorize a Bizum payment

Call authorize a payment with bizum as the paymentMethodCode.
Authorize request
The payment stays pending until the customer approves it in their banking app. Confirm the result through webhook notifications or the execution status before you fulfill the order.

How Checkout.com handles Bizum

  • Payrails creates the Bizum payment through the Checkout.com Payment Setup API, and sends the phone number to Checkout.com on the customer.
  • Payrails checks that both the phone number and the dialing code are present before it calls Checkout.com.
  • A Bizum payment needs no redirect. Payrails keeps the payment pending until Checkout.com sends the final result as a webhook notification.
  • Each Bizum payment is a new customer-initiated payment.
