Custom webhook: Content-Length and Host headers

Hi,

Looks like Custom request webhook does not automatically include “Content-Length” and/or “Host” headers. However, when I use GET/POST or PUT request (not custom request), looks like the headers are included, but I cannot use them as I need custom request body because I am working with GraphQL API.

 

How do I add “Content-Length” and/or “Host” headers to “Custom request” Webhook?

 

Thanks!

Thanks! The problem was that the GraphQL queries should always contain “query” and “variables” fields on the top level, I didn’t know that so the request was malformed. The `Content-Length` and `Host` belong to the headers that cannot be modified and are added automatically by the client (according to fetch standard: https://fetch.spec.whatwg.org/#forbidden-header-name)

 

Thanks again for your answers, this thread can be closed.

Also I’ve used POST request with Graph QL before, not via the Custom Method option.

Example with Monday.com

Hi @turis 

That’s generally indicated by the API you’re sending data to.

What values should I put there?

Hi @turis 

Try using the Headers section at the bottom of the Webhooks action step
