Welcome to Kwick Receipts integration section for Payment providers

With the Payment Provider integration, you send transaction-based callback requests to Kwick Receipts and receive matched receipt data when available.

The integration concept is transaction-first. This means the matching flow is based on transaction data rather than user registration or token-based setup.

Before you start, we recommend that you:

contact support@kwick.io and have your account and environment set up
read Transaction first for the integration concept
read Transaction definition for the transaction payload structure
read Create callback request and Update callback request for the request format
read 3 step integration for the onboarding flow

In short, the Payment Provider flow consists of:

sending transaction data to Kwick Receipts
creating or updating callback requests
receiving matched receipt data when available
