[#1511] Booking API Not Working on simplybook.pro

Hello SimplyBook Support,

I am experiencing a serious issue while trying to create bookings using the SimplyBook API.

According to your official documentation, the User API is supposed to work on simplybook.me, however the actual working API endpoint provided by your support team and used in production is simplybook.pro. This mismatch is causing failures in our API integration.

I am sending booking requests to this endpoint:

POST https://user-api-v2.simplybook.pro/admin/bookings

Headers
X-Company-Login: madrcuae
X-Token: [VALID TOKEN]
Content-Type: application/json

Request Body
{
“count”: 1,
“start_datetime”: “2026-12-02 09:30:00”,
“category_id”: 9,
“service_id”: 20,
“client_id”: 242
}

These IDs are coming directly from SimplyBook via API/webhooks:

Category: Physiotherapy session premium (ID: 9)

Service ID: 20

Client ID: 242

Even though all values are valid and exist in the system, the booking is not created and the API returns errors or behaves differently than described in the documentation.

Main issues

The documentation refers to simplybook.me, but the real API runs on simplybook.pro

The same headers, body, and parameters that should work do not behave correctly on .pro

Support-provided endpoints behave differently from the published API documentation

This is blocking our live booking system and webhook-based automation.

Please clarify:

Which domain is officially supported: simplybook.me or simplybook.pro

Why the same request fails on .pro

If any additional permissions, headers, or parameters are required for booking creation

We urgently need a correct and reliable API specification.

Thank you.

} - this is not a full create booking request. If you want to get list of bookings then you need to use just a REST API which is simply a get request API documentation | SimplyBook.me Online Scheduling
