Create and Pay Requests

The Request Network API provides an interface for creating and paying requests within your application.

Core Functionality

At its core, the Request Network API empowers you to:

• Create Requests: Define payment requests with information such as payee, payer (optional), amount, currency, and recurrence (optional).

• Facilitate Payments: Return transaction calldata, ready to be signed by end-users and sent to the blockchain for secure and transparent value transfer.

• Deliver Webhook Notifications: Receive instant updates on payment status changes, enabling your application to react dynamically to completed transactions.

• Fee Collection: When paying a request, you can specify a fee percentage (between 0 and 100) and a fee address, which will add the fee on top of the payment amount - meaning the payer will pay the original amount plus the fee percentage, with the fee portion being sent to the specified fee address.

• Partial Payment Support: Pay a portion of a request instead of the full amount at once. This unlocks powerful use cases such as:

  • Split payment: split a payment 50% USDC on Base and 50% with USDT on Optimism.

  • Gradual payment plans: Allow users to pay large invoices in smaller chunks.

  • Risk mitigation: Test with small amounts before completing large payments.

  The API automatically tracks payment progress, showing partially_paid status until the request is fully paid, and prevents overpayment by capping amounts to the remaining balance.

Get payment calldata

get

/v2/request/{requestId}/pay

Get the calldata needed to pay a request. For same-chain payments, returns transaction calldata that can be directly executed. For crosschain payments (when chain and token parameters are provided and differ from the request's native chain), returns a payment intent that needs to be signed and processed through the crosschain bridge. For off-ramp payments, use the query parameters clientUserId and paymentDetailsId. Note: Crosschain requests with an expectedAmount less than 1 are rejected.
