Callbacks
Notification Service
This section covers how webhooks are used to notify about events that happen in an E-wallet Program. Some events, like disputed charges or account status changes, are not the result of a direct API request. Webhooks solve these problems by letting you provide a URL to which we will send a notification anytime such an event happens. The "Notification Target URL" will recive a JSON payload depending on the notification type. Based on your integration requirements the individual notifications have to be turned on. Please contact Customer Support or your administrator to check your individual integration use case.
Authentication Options
Any of the below authentication methods can be selected for the corresponding program:
| Authentication Type | Behavior |
|---|---|
| No Authentication | No authentication information is sent in the requests to the "Notification Target URL". IP Whitelisting is mandatory in this case. Please contact Customer Support or your Administrator for the IP address which must be whitelisted. |
| Basic Authentication | The authentication is done by specifying a Username and Password under the "Notification Service Settings". These fields are used for basic authentication for every call made to the "Notifications Target URL". |
| OAuth Authentication | The Authentication URL along with the Username and Password must be specified. They are used for OAuth authentication to get a token via Client Credentials Grant. This authentication token is then attached to every call to "Notification Target URL". |
Notification Types
There are 2 distinct notification types:
- Program Specific Notifications - sending more detailed transaction information regarding the entire program, in addition to user management, compliance and others.
- Merchant Specific Notifications - only sending transaction related information regarding a specific merchant. They can be configured for each individual merchant.
You can provide a different endpoint for the Program' Notifications and each Merchant's Notifications. Please coordinate with your Product Solution Specialist.
