Authorize a transaction in a mobile app

Before you start a sale transaction in mobile app using the mobile transaction API endpoint, make sure you have the following:

✅ API key issued by Xplor Pay.

✅ Mobile JSON Web Token (mobilejwt) returned by the successfulTransactionToken method using the JavaScript SDK integration.

To create a multi-use or durable card token (id)when authorizing a transaction in mobile app:

1. Add the create-token field with a value of true to the request body when calling the mobile transaction API endpoint to authorize a transaction in mobile app.

{
   "type": "AUTH",
   "amount": "0.00",
   "create-token": "true"
   "software-type": "My Cool Software"
   "software-type-version": "1.0",
     "billing":
    {
      "zip": "85284"
    }
}

1. Use the POST method to call the rest/v2/mobile/transactions/auth endpoint.

The API returns the following response:

{
    "code": "200",
    "status": "success",
    "exchange-id": "ID-clearent-mobile-jwt-1-e4795490-49d8-4302-b2c6-fc46ea001bc9",
