Level of access needed for API

[Peter Watt]

We have an integration both with Jira Service Desk and Jira Software. Our customers regularly have issues with not having the correct level of access needed in order to see the data. 

Our integration with Jira is that we pull ticket information to show it in our system. So we need access to the issues, and usually any related fields (standard and custom) that are on that ticket. 

Can you please provide what level of access the authenticated user would need in order to see this information?

In our testing we have found that the user needs to be added to the specific project they are trying to see the issues in. However, this doesnt seem to be all of the access that is required.

They need the same access they need to do these things in the UI.  Authenticated account, the right permissions ("added to a project" probably isn't all they need - check what the permissions scheme and role lists say.
