# slot_not_available

**HTTP status:** 409 (Conflict)

**Title:** Slot not available

## Cause

That time is no longer free in the agenda, or it was never one of its slots. Nothing was booked.

## How to fix it

Read the availability of the agenda again and pick another slot. Repeating the same start will not work.

Call the endpoint named below first, then send the request again.

Endpoint: `GET /v2/scheduling/availability`

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
