Response handling

In the one-time-use token request, Google Pay gets returned in the paymentMethod parameter as googlePayAuthNet.

Nexio responds with transaction results in one of the following ways, depending on your integration workflow:

  • Event messages: This applies to integrations that do not pass a customerRedirectUrl in the request.
  • Response fields in the URL: This applies to integrations that do provide a customerRedirectUrl in the request.

In addition to one of the above, if your merchant account is configured to receive webhooks, Nexio provides responses to the webhook URLs that have been registered. For further explanation of the webhook event types, see the webhook Event types table.

  • Webhook notification: For Google Pay, these are the possible webhook event types:

For information about how to run each of the integration workflows, see Transaction types above.
