List user participants for an Appointment Group not showing all users

[gwoolver]

When using the API to GET a list of participants in an appointment group, I only get 10 results when over 200 are expected. 

I first get a list of all appointment groups. There's only one group that contains 16 appointments. 

https://<canvas>:443/api/v1/appointment_groups/13633?include[]=appointments

The response is correct: It returns the ID of the appointment group and each individual appointment. 

Using the ID of the group, I request a list of the registered users using the API call for "List user participants."

https://<canvas>/api/v1/appointment_groups/13633/users?registration_status=all

The result lists only 10 students and it doesn't tell me which appointment time they're registered for. 

Can anyone help me figure out how to:

1 - Get all users registered for an appointment?

2 - See which appointment they're registered for?

Maybe I'm going about this from the wrong perspective. If I should be doing this a different way, please let me know.

More Info

I have a single appointment group with 16 appointment times. Each appointment time allows 21 students to register. They're registering for a time to take a proctored exam, so I'd like to have a list to check them into the exam room. I would also like to see which students have not yet registered so I can remind them to sign up for an appointment. I am doing my testing in Postman. I get the same results in Firefox. 

Thank you.

Hi  @gwoolver ,

The 10 results is something pretty common, I would firstly recommend checking out Pagination - Canvas LMS REST API Documentation. You will need to specifically parse and pull additional pages of items based on the Link header in the API replies you get from Canvas.

With regards to the time the individual users are registered for, from what I can tell this sits on the AppointmentGroup object in the API under "reserved_times". Without having a construct in a test system, I am not able to specifically test this, but reading into the API in more detail, what information are you getting on your first call to list assignment groups under the “child_events” parameter?

From what I can surmise in the API documentation, it seems this is where the child events would be populated. Would be great to see a redacted example of a response with that included if all possible!

Look forward to hearing from you!
