[SalesForce] Apex Web Services Trailhead

You have to authenticate before you can call the rest resource. You authentication is what allows you to access the endpoint

A little while ago, Paul McGurn blogged how to create a public (SOAP-based) web service via a Force.com Site. As Paul explains, you add your web service class to the Enabled Apex Classes in the Site’s Public Access Settings. You’ll also need to add the appropriate object and field-level permissions for any data you will be exposing; remembering, of course, that this web service will be accessible without any authentication!

As I was setting up a WebHook the other day, I realized that the same principle applies to Apex REST Methods – add the class and any relevant objects/fields to your Site’s Public Access Settings, and you can access the REST methods via the Site URL. Let’s code up a simple example; here’s my Apex class:

Kindly Update test class AccountManagerTest. Also add base url in Remote Site Settings.

@isTest
private class AccountManagerTest { 
    @isTest static void testAccountManager() {
        Id recordId = createTestRecord();

        Contact Cont1 = new Contact();
        Cont1.LastName = 'ABC';
        Cont1.AccountId = recordId ;
        insert Cont1;

        Contact Cont2 = new Contact();
        Cont2.LastName = 'XYZ';
        Cont2.AccountId = recordId ;
        insert Cont2 ;

        RestRequest request = new RestRequest();
        request.requestUri =
            'https://{baseurl}/services/apexrest/Accounts/'+recordId+'/contacts';
        request.httpMethod = 'GET';
        RestContext.request = request;
       Account lst = AccountManager.getAccount();
       /* Tried to return Contact List but failed Trailhead Verification
       List<Contact> lst = new List<Contact>();
       lst = AccountManager.getAccount();
       */
    }

    static Id createTestRecord() {
        Account accTest = new Account(Name='Test Record');
        insert accTest ;
        return accTest.Id;
    }          

}
