Unable to expose data using web API

Your browser does not send any authentication credentials. So Appian does not know who you are and asks for a login. That's pretty normal and Appian does not enforce OAuth.

But, I must admit that it might be that the CE behaves a bit different. Try to get an answer from communityedition@appian.com

I believe Appian uses OAuth 2.0 authentication by default for Web APIs because whenever I try to open my endpoint in a new browser, it redirects me to the Appian login page. Where can I change the authentication method for my Web API to Basic Authentication, other than through the Admin Console?

This should work. Find the documentation here: https://docs.appian.com/suite/help/24.4/Web_API_Authentication.html#basic-authentication

I was just testing it on Postman. After selecting Basic Auth, even though I am entering my Appian username and password correctly, it is showing me 'Authentication failed. Please check your credentials and try again.

For testing purposes, you could use a basic authentication using your normal user account.
