Hey,

Bit odd, this as the error states it expecting but when I look at a template I got from the market place, I don’t see the HTTP request nodes doing that.

This seems to be the error:

"POST method requires request_body_schema"

This means that when you’re configuring a POST request from n8n’s Webhook, ElevenLabs expects a specific request body (JSON) schema — but the webhook is not sending that body, or it’s not correctly formatted.

This is the template I imported, so maybe worth checking it out too.

Hope this helps.

I am having similar issue. But this does not seem to be issue from n8n side, rather it’s ElevanLabs issue.

When I am trying to create Webhook in ElevanLabs agent (as a tool), it does not allow me to “save” for POST method. it’s allowing me to save for “GET” method, but for Elevanlabs agent to call n8n, it has to be POST method.

While creating this POST webhook, it asks for Body Parameters and Description, and despite filling in all correct details multimes (been on this issue for past 2 days now), it does not allow us to save.

It seems to be bug in ElevanLabs product. It also does not allow to edit the JSON.
