I've made an API in Appian, but am having the hardest time understanding how exactly one connects to it externally.
According to the documentation: https://docs.appian.com/suite/help/21.4/Web_API_Authentication.html
I should be able to connect to it this way: example.appian.com/.../endpoint -H "Appian-API-Key: ${API_KEY}"
I put in my endpoint and API key, but every time I get an authentication error, so clearly I must be doing something wrong.
Could someone walk me through the exact steps to get this to work?

create a basic user & provide access to your application & API.After that from where you are calling the api use basic authentication. & provide the user name & password of the basic user. It should work, its working for me when I try to call my appian API from Postman
