Client setup

Credentials must be provided to the client (i.e. you) for implementation. The client credentials are unique per client implementation and are obtained by requesting a product API key from Snapplify.

Client credentials consist of the following values, which will be supplied by Snapplify:

Payment states

A payment state indicates the state of the payment. When your customer’s payment is being processed on Snapplify Pay, it can go through the following states:

Pay endpoints

API and HTTP endpoints are used to integrate with Snapplify Pay. There are three endpoints of which two are API requests and one is an HTTP redirect, as follows:

Payment request

The payment request creates a new payment and returns a token, which is used to submit a payment in subsequent steps. The request must be done from server-to-server and include your unique secret, in addition to the client and other parameters.

Please note: This is a server-to-server call.

POST /payment/request?client=XXX&secret=XXX
Host: pay.snapplify.com

Payment submit

Payment validation

The payment validation step is not strictly required but we highly recommend its use. The purpose of this API endpoint is to check that the payment is authentic.

A partner or developer may check the payment.referenceCode against the referenceCode sent during the payment request call.

Please note: This is a server-to-server call.

POST /payment/validate?
client=XXXYYYZZZ&secret=XXXYYYZZZ&token=XXXYYYZZZ
