Assigning service name to job number

I need to find a way to get a report that shows the service name/type from the services add on, and to have it linked to the correct job numbers so I can work out which services are more profitable for the business.

I know that there are ways to do it as I used to use a 3rd party program that was pulling that data from serviceM8 for their custom reports, but I have not yet been able to find anything in the openAPI that allows for this, there is no custom field in the jobs API that shows the Services uuid or any of the other public URL's

I have managed to find the services API that is similar to the Category API under the URL https://api.servicem8.com/api_1.0/service.json

So i was wondering if there was a specific endpoint that I needed to call that is not showing on the website?

Any help would be greatly appreciated
