What's New

Additional HTTP Methods

Beyond POST, you can now use:

GET — Retrieve data requests
PUT — Update data requests
HEAD — Header-only requests
OPTIONS — Pre-flight requests

HEAD and OPTIONS return 200 success responses automatically.

Query Parameters Access

Parameters in your webhook URL are now accessible:

https://your-webhook-url.com?source=facebook&campaign=summer

Both source and campaign are available as variables in your workflow.

Headers Access

HTTP headers sent with the request are saved in the payload. Useful for:

API keys
Authentication tokens
Source identification

Custom Variables with Spaces

You can now reference custom variables that have spaces in their names.

Contact Reference Options

The inbound webhook can automatically link to existing contacts using:

Email — Match by email address
Phone — Match by phone number

If a match is found, the workflow runs in that contact's context.
