POST /platform/v1/ens-callbacks
Registers a new callback to receive event notifications. You must register and verify your callback before you use it in a subscription.
| Name | Type | Description |
|---|---|---|
callbackName | string | Required. The name of the callback. |
url | string | Required. The URL of the customer callback that receives event notifications in the format https://host[/path]. Ports and query string aren’t supported. The URL must be syntactically correct and not already registered as a callback URL. |
maxBatchSize | integer | The maximum number of events that this callback can receive in a single call. The default value is 1,000. For the minimum and maximum batch sizes, see API Limits and Guidelines. |
Your URL endpoint must be online and reachable before you create a callback. The Event Notification Service immediately attempts to post verification details to the endpoint.
If your callback doesn’t respond within 30 seconds or returns an HTTP response other than 200 OK, the callback creation request fails with a 400 Bad Request status. In this situation, the response includes a description of the failure, similar to this example.
| Response | Reason |
|---|---|
| 201 Created | The callback was created. |
| 304 No Change | The callback already exists on the server. |
| 400 Bad Request | The server was unable to process the request. |
| 403 Forbidden | The server was unable to authorize the request. |
| 500 Server Error | An internal error occurred. |
