The endpoints of the REST API specify a particular table from the database that you want to access. Some of those tables are related to other information - tickets are connected to the patrons that bought them, the event that it is for, and the performance time that the patron purchased. You can add in some fo that additional table connections by specifying them.

The starting place is finding what data is related to a particular endpoint using the related feature. The following shows:

• https://127.0.0.1/api/v1/patrons/related - relationships to any patron record
• https://127.0.0.1/api/v1/patrons/51/related - relationships for a specific patron record (#51) which can be followed to see data for that patron.
• https://127.0.0.1/api/v1/marketing/related - relationships for a particular marketing record for the patron so that you can retrieve things like the primary email address, phone, or physical address

Once you know which data is related, you can start to include that data onto the URL. In a one to many relationship, you normally start with the child or collection record.

Examples are:

• https://127.0.0.1/api/v1/performances?q=perform_datetime:2016-01-01..2016-12-31&include=event
  In addition to data from the performance endpoint there is now data from the event endpoint on the end of each row of data.
