Web API Authentication

Question

How do I authenticate users if I want a third party platform to access a JSON query that is produced from my Web API

Hi ashleyk0001 I believe you can follow below steps to invoke Appian Web API from external systems. 
 
1. Create a Web API which returns a JSON response 
 
2. Navigate to Admin console and under Third Party Credentials, create an Entry, where if the user is of type Basic User then add this user or their respective groups to Web API security, but if user is of type Admin then no need of adding him to Web API security (To avoid Unauthorised Access Exception) 
 
3. Now you can provide your Web API and Third party credentials username and password to third party system who wants to consume your service, and while invoking this API from external system, they can set preemptive to true() 
 
You don't need to have SAML Authentication enabled for this. 
 
Hope this will help you.

Hi, there are two options per the documentation: Standard forms-based login HTTP basic authentication I'd recommend reading more under "Authentication" here: docs.appian.com/.../Web_APIs.html

If I understand your question correctly. You are trying to call your web api from external system then basically you no need to do anything. Provide your URL. And provide username and password which is having access to that web api(loot at the security settings of web api). That's enough, Appian automatically validates it. 
 
You can test your web api in the below url.
