Salesforce Rest System.HttpResponse [Status=Not Found, StatusCode=404]

Question

I need to invoke a REST class exposed in my own developer edition org.   Its a GET Method, and when I test the endpoint using Workbench, I get the expected result.

Now the problem is, I created a new Remote Site Setting and pasted the URL from my own org. In this case remote site setting which i saved is https://ckdomaintest-dev-ed.my.salesforce.com and invoking the same method with same parameters is not executing properly.

I am getting the following error:

System.HttpResponse [Status=Not Found, StatusCode=404]

So I feel the remote site is not being recognized. How do I call my own org?

Answer 1

To do that you need to call the

1. standard REST API to get you authenticated

2. Understand the different authentication

3. Once you are done with authentication call your custom API with access token received from step 2.

You can get sample code from here and here and from the links provided

generally, we don't call rest API in the same org most of the time we call rest api of another salesforce org. if you are already inside of the salesforce org and want to invoke the custom rest api you need to set the header.

req.setHeader('Authorization', 'OAuth '+UserInfo.getSessionId());

Hope this helps.
