Cannot access the process model from integration object

Question

I have configured a process model with script task which takes two inputs and result will be the addition of two inputs. Now I have created a Web-API to start the particular process and have used the Web-API in integration object. I have provided the correct credentials(basic credentials) but I am facing with Forbidden error(error 401 unauthorized). 
 Any inputs will be helpful.

HI Santosh, 
 
check the user credentials you pass has access to webAPI. The user you use in credentials should be part of at least viewer group of the webAPI to invoke it. You will get 404 error when your user does not have access to initiate the webAPI

Hi rohitr303 
 
How are you buddy hope doing good. 
 
For your error response most of the time answer will be access issues. So seems like you are able to call the webAPI that mean user have proper level of security to invoke the webAPI (I assume you are also using webAPI). Now the next thing to check is what type of objects you call inside your webAPI - this could be process model/datastore. Now check if the requesting user have access to those objects. internal server error 500 is a very generic error, but when calling webAPI in Appian most of the time http 500 occurs when user does not have access to the resources/objects that are called with in webAPI.
