Exporting All End Users (API)

We are a Suite Growth customer.  I am trying to do a full end-user export.   Using the API, it limits me to 100 users.  I am using the /api/v2/users endpoint.  

We are currently importing current students and their guardians as end-users in our system so key information is on their user records, but when students leave the district, we no longer need to keep their records - just trying to be conscientious about system maintenance. 

Any suggestions would be appreciated. 

Thank you in advance
