MS Graph API - Cannot List Booking Businesses

Question

Microsoft Graph API v1 for Bookings states that you can list booking business: https://learn.microsoft.com/en-us/graph/api/bookingbusiness-list?view=graph-rest-1.0

{
    "error": {
        "code": "",
        "message": "An error has occurred.",
        "innerError": {
            "date": "2023-04-14T14:45:40",
            "request-id": "f1adc4f7-fd7e-4ecf-bd4b-b8b71b907151",
            "client-request-id": "f1adc4f7-fd7e-4ecf-bd4b-b8b71b907151"
        }
    }
}

I'm just making the authenticated call using postman: https://graph.microsoft.com/v1.0/solutions/bookingBusinesses

Answer 1

Hello Pablo,

Thanks for reaching out!

As per my testing, it seems you are trying to list bookingBusinesses using Application Permissions in Postman, which is not supported as per the documentation. The endpoint is only supported to work with delegated permissions (with signed-in user present).

Hope this helps.

Hi HarmeetSingh7172,

It is possible to use postman to list all booking business, you just need to add the corresponding API permissions in the app registration and refresh the token.

Regards!
