New CustomField Webhook Type

We have introduced a new webhook type for CustomField updates. You can now subscribe to events that notify you when Custom Field values are created or updated.

To subscribe to changes in Custom Field values, make a POST request to /v3/WebhookSubscriptions using the type CustomField in the payload.

For example:

{
    "TargetUrl": "https://example.com/webhook",
    "WebhookType": "CustomField"
}

Note: You will receive a webhook for each Custom Field value that is added or updated. This may result in a large number of notifications.

New WorkScheduleKey Filter for WorkItems Endpoint

You can now filter Work Items by their associated Work Schedule. Use the WorkScheduleKey parameter in a GET request to the /v3/WorkItems endpoint.

For example: /v3/WorkItems?$filter=WorkScheduleKey eq 'FXcWYY9xZfd'
