NamedCredential URL path and Endpoint Callout path is different

Question

I have a requirement to integrate Salesforce with external system, the Endpoint APIs are provided and i am using Named Credentials for making the callouts using Apex:

Below is the details for Authentication ENDPoint:

• URL : www.example.com/authenticate
• Method : POST
• Header : apiKey : "afdsfgfddkgk"
• Username : admin
• Password : admin

I created a Named Credentials with the URL provided with below configuration

After authentication i have to make a call to the below Product Details URL to fetch the details

• URL : www.example.com/v1/pickup-requests

Note there is a slight difference in the path, my product details endpoint doesn't have authenticate in the path where as Named Credentials has.

When making the callout i am using the below Apex code:

   HttpRequest req = new HttpRequest();
   req.setEndpoint('callout:ApiCredentials/v1/pickup-requests');
   req.setMethod('GET');
   Http http = new Http();
   HTTPResponse resp = http.send(req);

When i debug the log the Endpoint changes to www.example.com/authenticate/v1/pickup-requests.

Question : Is there a way to get rid of path /authenticate while making callouts.

Thanks in advance

Answer 1

Don't include "authenticate" in the Named Credentials URL. Then, you can change your authorization call to: callout:ApiCredentials/authenticate. It's generally advisable to not include a path in the Named Credential unless the entire API is located under that path.
