The final step of every payment transaction, regardless of the service type, is to get notified of the outcome - i.e. whether the payment was successful or not. Payment result notification provides you with all the relevant data for your further processing.

In order to have this option activated you need to provide URL of notification handling endpoint (i.e. web service which handles notifications). Upon transaction reaching its final state, Centili will invoke provided notification handling endpoint, with the following parameters:

## Examples

  • **One-time payment notification sent using HTTP GET method:**


  • **Subscription payment notification sent using HTTP GET method:**



## Payment Result Notification response

After invoking your notification handling endpoint on provided notification handling URL, we are expecting a HTTP response with one of the following statuses:

  • ## HTTP status 200

    Result notification is sucessfully completed on your side. Transaction notification status is marked as **success** on transaction page in Centili Partner Panel.

  • ## HTTP status 406

    Result notification is rejected (_Not acceptable_) and we will immediately discontinue notification for that transaction. Transaction notification status is marked as **rejected** on transaction page in Centili Partner Panel.

  • ## All other HTTP statuses

    When neither http status 200 nor status 406 is returned (e.g. your server goes offline or any other error occurs), then Centili will keep retrying notifying you 3 times during the next 30 minutes. Undelivered payment result notification will be marked in Centili Partner Panel transactions page and you will also be able to resend them to your URL manually.

## Resending undelivered payment result notifications

On **[Centili Partner Panel](🔗)** transactions page you can:

  • ## Resend single payment result notification

    When there is payment result notification with status failed you can resend payment result notification for that transaction and this is done immediately.

  • ## Resend bulk payment result notification

    When multiple transactions have the payment result notification status failed you can resend payment result notification for multiple transactions together. All of the selected payment result notifications will be queued for sending.
