I'm using the new API Gateway HTTP to make requests to 3rd party APIs. This works great for GET requests but doesn't work for POST requests due to CORS preflight.
When I try to make a request this is the error I get on the chrome console...
From the docs it says to add Access-Control-Allow-Methods to * and Access-Control-Allow-Origin to * but POST requests triggers a pre flight request and this is failing.
Any help appreciated!
Double-check your Access-Control-Allow-Headers. If it's missing any headers that are sent on the request it will silently fail.
I had the same issue (works for GET but not POST) because I had forgotten to add the content-type header to the list. This is a common header sent with POST requests and I can see it is missing in your example.
It may also help to examine the failed network requests in the browser console to see which headers are being sent.
