[SalesForce] Server returned HTTP response code: 500

External third party service is occasionally getting Server returned HTTP response code: 500 when it does a POST to salesforce webservice class, but only occasionally. Most of the times it is working fine.

URL:https://domainurl/services/apexrest/classname . Here, domainurl is a public site url.Hence, whenever this webservice gets executed, it always gets executed by the same `Guest USER'

How can I debug such error especially when everything works out I am trying to post. AND Is there any way I can make a log in salesforce whenever such error is sent out?

As this seems to be a Lightning Platform error (see "status codes and error responses"), I'd definitely open a support case. Maybe you're lucky and they are able to log something. Be sure to tell them the time such an error occurred.

I had a hard time logging webservice communication in Salesforce as it basically doesn't exist (apart from Login Logs) and even the Support wasn't able to access anything useful apart from apex class logs.

You are using the wrong URL I think

Try this: https://chale1-developer-edition.na14.force.com/test/services/apexrest/helloWorld

EDIT - When I looked at the HTML that came back original URL in Postman, I saw this message:

https://chale1-developer-edition.na14.force.com/test</i> is down for maintenance

So I realized he must have used added a suffix to the Default Web Address in the Site called test. The REST URL includes the default suffix as part of the full URL, so I added that the URL he provided, and it worked...

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:
