This API reference includes IPAY APIs, which are REST APIs exposed by the IPAY backend. They are typically used to create new transaction or carrier labels to request payments from consumers by scanning QR-Code with their mobile phone camera (COD; Cash On Delivery).All endpoints are prefixed with different names, like Api or Auth. IPAY does not offer a test API environment, but rather a TEST Merchant Channel API Key so you can test with this key. Also if you need to test payments you can specify TestMode on certain calls, so all payments will use our company test accounts to mimic a payment.We try make our API documentation as clear as possible, but if you need more help, please contact our support department by sending a mail to support@ipay-solutions.com
