Steps
Authenticate with the Authorization: token <API KEY> header against https://app.tutorcruncher.com/api/
POST to /api/clients/ (or /api/recipients/ for a Student) with a nested 'user' object containing at least email and last_name
To set a custom field, include it inside 'extra_attrs' as an object keyed by the field's machine name, e.g. {'client_dob': '1993-06-23'}, not as the raw extra_attrs array returned in GET responses
To update an existing person instead of creating a duplicate, POST to the detail URL /api/clients/<id>/ with the same payload shape
Check the response 'status' field for 'success' and inspect the returned extra_attrs array to confirm the custom field machine_name and value were applied
Known gotchas
TutorCruncher treats email as the unique identifier for matching an existing user on create; if you omit email, last_name becomes required instead
Dropdown-type custom fields must be posted using the slugified option value (lowercase, spaces/punctuation converted to single dashes), not the human-readable label
Posting to the list endpoint always attempts a create in the current API version — updates must target the specific role's detail URL by ID, not by email
