Capture Pre-auth request

An overview of the Capture Pre-auth request message for Android.

Overview

👉 The Capture Pre-auth request is used to capture a pre-authorisation transaction.

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.

For a typical Capture Pre-auth request, the client app must provide the following information:

    Capture Pre-auth response

    After executing a Capture Pre-auth transaction the ‘viva.com | Terminal’ application responds with a Capture Pre-auth response result to indicate if the transaction has been approved or not.

    Uri result = getIntent().getData()`
