Hi All: I have a situation where the partner will be sending the HTTP OPTIONS before sending actual POST body . we need to send them a "custom header back when they srnd http OPTIONS. when i test from postman it shows 200 OK for OPTIONS but it doesn’t triggger the _default. But I am not able to capture the savepipeline, I mean it doesn’t kick in the REST method. I am not sure maybe server is responding with 200 and not letting the OPTIONS hit the code. I created _post and _default event. What extended settings do I need to add. I have the below at the moment.
