Single Payment

Every Feezback payment link follows the same underlying pattern:

1. You sign a JWT (RS512) describing the details of the requested payment
   1. Amount
   2. Currency
   3. Creditor account
   4. Debtor details (optional)
   5. UI flow configurations (optional).
2. You POST it to Feezback's Link Generation Service (LGS), which validates it and returns a link.
3. You redirect the user to the link (from your app/website) or send that link to the debtor via offline channels (email, SMS, in-app, a QR code, wherever makes sense for your product).
4. The debtor opens the link and gets redirected for authentication and approval at their bank portal/app .
5. You receive a webhook with the final payment status, plus the debtor ID and account details if.

Public vs. personal link

• The JWT content is what makes a link specific: the amount, the creditor, and the debtor details may be predefined or added by the customer according to your business scenario.
• You can create a public, reusable link with open amount to be used as QR code for payments.
