# Update booking question answers for an appointment

`PATCH /api/v1/appointments/{appointment_id}/booking_questions`

## Request

- Base URL: `https://api.checkcherry.com`
- URL: `https://api.checkcherry.com/api/v1/appointments/{appointment_id}/booking_questions`
- Auth: none declared. Required headers: `Api-Key`

Updates one or more booking question answers on the appointment. The body's `custom_questions` keys must match the `column_name` of each booking question (as returned by the `GET` endpoint). Built-in fields (e.g. `guest_phone`, `event_date`, `venue_name`) are also accepted here.

Only the keys you include are touched — other answers on the appointment are preserved.

**Note:** booking questions are sourced from the appointment's calendar. Appointments not created from a calendar (e.g. Quick Add) have no associated questions, so this endpoint is a no-op for them — use `PATCH /api/v1/appointments/{id}` to update guest/venue/event fields directly in that case.

**Required permission:** `assigned_appointment_write` or `unassigned_appointment_write`

## Path parameters

- `appointment_id` integer, required

## Headers

- `Api-Key` string, required

## Request body

- object
  - `custom_questions` object, required: Keys are booking-question column names; values are the answer to record.

## Response `200`

booking questions updated
