Calling a Appian Web API from Appian itself

Question

Hi All, 
 
 We have created a web API in Appian and trying to call the same from a!httpQuery function in an expression. It is giving an authentication error as expected. 
 Can someone please suggest how we could add the authentication bit. Do we need to do some settings in the admin console and use it here or some other way. 
 
 Thanks. 
 Hitesh

Hi Hitesh, for this you have to set up the authentication credential in the admin console and then use a!scsField() to retrieve the same. Links for related documentation:
