POST /invitees returning invalid_location_choice even when event_type.locations matches location_configuration.kind

Hi ​@phillykish  - Thanks for reaching out with your detailed example!

After taking a closer look here, I can confirm that for our POST /invitees endpoint (docs here), the field to send is location, not location_configuration.

For a Zoom event type, you should not need any additional field inside location beyond the kind itself. Your request should look something like this:

{
  "event_type": "//api-calendly-com.screenshare.banktechpr.app/event_types/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "start_time": "2026-02-17T16:15:00Z",
  "invitee": {
    "email": "test@example.com",
    "name": "Test User",
    "timezone": "America/New_York"
  },
  "location": {
    "kind": "zoom_conference"
  }
}

A couple of related notes:

• location.location is used for location types where a value needs to be supplied, such as physical, custom, ask_invitee, or outbound_call.
• For zoom_conference, sending just the kind should be sufficient.

So based on what you shared, the most likely cause of the invalid_location_choice error is the request using location_configuration instead of the public API's location field.

If you're already sending location and still seeing the same error, that would be unexpected based on the public API behavior and would be worth reporting to Developer Support by submitting a ticket here with the full raw request and response payload.
