Error: The Sync ID Field Is Required

Issue

While creating a webhook in Postman by providing a URL and event types, the following error appears:

The sync id field is required.

Environment

• Fivetran REST API
• Webhooks

Resolution

To resolve this, ensure your endpoint can accept payloads without a sync_id field, then create the webhook again.

Cause

When you create a webhook, we ensure the URL you provide is accessible and can receive data by sending a test payload in the following format:

{
  "event": "test_event",
  "created": "timestamp",
  "connector_type": "_connector_type",
  "connector_id": "_connector_1",
  "group_id": "_destination_1"
}

However, the payload we send doesn't include a sync_id field. This issue occurs when your endpoint doesn't accept payloads without a sync_id field.
