Asynchronous actions and communication by the Bango Platform
The Bango Payment API is a RESTful API: you make requests, and the Bango Platform returns responses. In some cases you might require out-of-band actions or communication from the Bango Platform, without an explicit request from your store.
The Bango Platform supports this in two ways:
POST requests from the Bango Platform to a URL of your choosing at the conclusion of an identification session or transaction authorization, where a web-based identification or transaction flow was used. Bango includes body parameters to help you identify the reason for the notification.Callbacks and notifications are similar but have important differences.
| Callback | Notification |
|---|---|
| Callback URLs are for users | Notification URLs are for servers |
| A callback URL references a web page that can be displayed to a user | A notification URL is a data transfer mechanism for server-to-server communication |
| Callbacks include parameters in the query string | Notifications include parameters in the POST body |
You can include custom query parameters in both callback URLs and notification URLs. However, some parameters are reserved: see Bango Payment / Merchant API reference / API reference overview and Bango Payment / Merchant API reference / API reference overview for the details.
