Technical Flow

Webhook and email notifications

At the time of the redirect, it is still uncertain whether a transaction will be completed successfully or not. Therefore, Payengine awaits for the final asynchronous notification before the status of a DEBIT transaction is changed from PENDING to SUCCESS or FAILURE.

A merchant should register for Payengine's notifications to receive this final status update.

Alternatively, a GET request on the order or DEBIT transaction would also work, but it is not ensured that the final status will be available immediately after the redirect and a merchant might have to query the GET multiple times.

Therefore, it is strongly recommended that Payengine's asynchronous notifications are used instead.

Merchants could receive notifications via URL (webhook) or email.

The notifications could be subscribed:

• via the payengine API (link to API documentation)
• via the Payengine Merchant Center (link to Merchant Center notifications documentation)
