I'm using the offical Zendesk PHP API client but I cannot find any documentation on how to get all tickets of a special group.
I already studied the README.MD on GitHub, the samples and also source code of the framework but I could not figure it out.
I have the group ID, but it would also be possible to search the tickets with a tag. Unfortunately I am not able to search for tickets, just for users.
After a few days Zendesk support got back to me, and the solution is quite simple if you know how:
With $client->search()->find('type:ticket group:GROUP_NAME')
you can use all query parameters described in the Zendesk API Documentation.
