I build and host an Applikation. So I use an HTTP-Endpoint and NOT AWS-Lambda. So the AWS Service API-Gateway doesn´t work for me. I build a Java-Spring-Boot Applikation, and I want to create automatic tests without using manually the developer-console. I want to use Postman to send requests. If I copy and paste the Request from the developer console into Postman and sent it against my endpoint, I get the following response:
How can I get the signature / certificate? If I log the header from the developer console and past it in postman, it doesn´t work as well.
Maybe I forgot some important header? Could someone tell me, which steps I need to do, so that I can send requests against my Endpoint with Postman?
