Overview

👉 The Rebate request is utilized to process a rebate to a Visa, Mastercard, or Maestro card (where supported by the customer’s bank).

The client app must implement a mechanism to send messages using Android intents and URI calls and to receive the result in a custom URI callback.

• Rebate request originating from the client app to initiate a request for a Rebate transaction.
• Rebate response originating from the ‘viva.com | Terminal’ application to return the result of a Rebate transaction.

Rebate response

After executing a Rebate transaction, or refund, the ‘viva.com | Terminal’ application responds with a Rebate response result to indicate if the refund has been approved or not.

The result is received as a URI in the callback activity intent:

Uri result = getIntent().getData()

The table below summarises the contents of an approved response.
