Requests can only be made to domains associated by this application. Read more about [API Request Setup](https://help.zapier.com/hc/en-us/articles/12899607716493).

Any parameters added to a URL will be URL-encoded and appended to the request URL to pass additional data to the API request.

These headers and values will be applied to the request in addition to any headers created as part of authentication. Authentication headers are added automatically.

Zapier will pass this along raw. If you would like to provide complex JSON, try a "Code by Zapier" step to build the structure and pass it along here. For example, `{"foo": "bar"}` is perfectly valid.
