Our Gateway API is a REST-based interface designed to simplify your payment processes. You can send us requests in JSON format, and we'll handle all the secure transmission, extensive validation, and processing with our payment gateway. We then return the transaction status directly to your system.

Security is built into our core. Our API includes authentication and authorization checks by default. You'll use your unique Configuration ID and a SHA512 hash in the HTTP header of every API call. This hash isn't just for authentication; it ensures your messages are consistent and protected from tampering. All payment details are sent securely via HTTPS POST requests, and for added security, you might also need to whitelist specific IP addresses.

 It's straightforward: just include your Configuration ID and the SHA512 hash in the HTTP header of each request. This combination authenticates your application and ensures the integrity of your data.

We support a wide range of global currencies, all compliant with ISO-4217, including GBP, EUR, USD, JPY, AUD, and CAD, among many others. For payment methods, you can process card payments easily, and we also support popular options like iDEAL, PayPal, and AfterPay. You can even use our API to dynamically retrieve a list of all supported payment methods via the SupportedPaymentMethods endpoint.

We provide a dedicated integration environment specifically for testing. This sandbox lets you simulate transactions and experiment with different payment scenarios without affecting any live data. Just reach out to us at techsupport@cashflows.com to request your integration account credentials—they're separate from your live production credentials.

For immediate feedback, our gateway uses standard HTTP response codes (e.g., 2xx for success and 4xx for issues) to indicate the status of your request directly. Our current documentation on the provided page does not explicitly detail the use of webhooks for asynchronous transaction status updates.

You'll see standard HTTP response codes to indicate the general status of a request. Beyond that, our API provides detailed error reports that include specific error and warning indicators, language, and a fatal error flag. These reports also link to relevant data, actions, and documentation to help you quickly understand and resolve any issues.

Our API provides clear pathways for these operations:

• Refunds: You can easily initiate refunds through specific API calls by using the post method.
• Cancellations: Both entire payment jobs and individual payments can be cancelled using a patch method, with clear endpoints like /api/gateway/payment-jobs/{paymentJobReference}/payments/{paymentReference}/cancel. You'll receive a 200 Payment cancelled successfully response upon completion.
• Recurring Payments: We support recurring payment flows with options like "IsRecurringPaymentJobParent" and the recurrenceCriteria parameter, which you can use when setting up new payment jobs and refunds.
