How do I configure CORS headers for Webhooks triggers?

I’m trying to put a Zapier Webhooks URL in my Marvin (amazingmarvin.com) webhooks settings. I have to do it this way because there are no triggers in the Marvin Zapier app (just actions).

Marvin says regarding webhooks:

To prevent Marvin from being a DOS machine, Webhooks are sent as AJAX requests from the client. That means that your target server needs to configure CORS. If this turns out to be a major inconvenience, this could be improved in the future. Go ahead and file an issue on github if you feel this would be worthwhile.

Which headers are needed?

Access-Control-Allow-Methods: OPTIONS, POST # whichever methods you are using!Access-Control-Allow-Headers: Content-Type,... # whichever you are specifying (+ content type unless using GET)Access-Control-Allow-Origin: https://app.amazingmarvin.com # use * if you want to use the desktop or mobile app

Hello! It will be authorisation headers… Based on this data here - You just need to send a POST request with a Bearer token. Have you tried this?

POST /api/test
X-API-Token: XYZ
=>
"OK"

It sounds like you are talking about sending data FROM Zapier TO Marvin, but I’m trying to do it the other way around (otherwise I would have just used the Zapier connection that Marvin made).

 

Something happens in Marvin, and then it needs to call my Zap in Zapier.
