Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://apidocs.akinon.com/commerce-openapis/checkout/wallet-and-redirection-payments/process-redirection-payment-callback.md). # Process Redirection Payment Callback Processes the callback returned by the external payment gateway after the customer completes or abandons the payment on the provider's hosted page. The gateway posts its result to this endpoint (or the browser is redirected back to it). Query parameters present on the incoming URL are automatically merged with the POST body before validation, so gateway implementations that return data as redirect query strings are handled transparently. The specific fields required vary by the active payment gateway. Most gateways include a `success` indicator; additional fields carry transaction identifiers, hash values, and status codes for server-side verification. **Preconditions**: * A redirection-based payment option must be selected * The redirect flow must have been started * The pre-order must have an assigned order number **Processing Flow**: 1. Merges GET query parameters from the callback redirect URL into the submitted data 2. Selects the gateway-specific input schema based on the active payment provider. **TeqPay note:** the gateway submits fields as `Token` and `Result` (capitalised); these are normalised to `token` and `result` before validation 3. Validates callback fields (transaction ID, hash, status codes). **Extension gateway note:** `installment_count` and `interest_fee` values from the callback are stored on the pre-order under `installment_alt` (`installment_count` + `installment_interest_amount`) for downstream order and interest calculation 4. Records a return transaction entry with the payment outcome 5. On success: finalises the order, submits the basket, sends order confirmation email and SMS notifications 6. On failure: rolls back the redirection state and resets the order number so the customer may retry from the payment selection step **Configuration**: * `USE_ONE_TIME_TOKEN` (dynamic setting, default: `true`): When enabled, a single-use token is appended to both the success and failure callback URLs at transaction start. The token is validated on return to prevent session replay. * `ORDERS_USE_ISOLATED_PRE_ORDER_ON_RETURN` (static setting, default: `false`): When enabled, an encoded order number is embedded in the callback URLs (`n` query parameter) to support isolated pre-order session recovery on return from the payment provider. ```json {"openapi":"3.1.0","info":{"title":"Overview","version":"1.0.0"},"tags":[{"name":"Wallet & Redirection Payments","description":"# Checkout Wallet & Redirection Payments\n\nIntegrate digital wallet payments and external payment provider redirects into your checkout.\n\n**Wallet** payments let customers pay using a pre-funded account balance.
