Dear Opsgenie-Community,


I'm currently implementing a web application in Angular to utilize the Opsgenie REST Api. The integration is already setup and it works when using Postman.

When I try to do a GET against the endpoint, my browser throws the dreaded CORS error:

Access to XMLHttpRequest at '' from origin 'https://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I feel like I'm missing something but I can't seem to find any option to whitelist my localhost in Opsgenie or any option to enable to tell Opsgenie to reply to the preflight with an Access Control Allow Origin header. What am I missing here?
