# reschedule_booking Behavior, inputs, outputs and permissions for reschedule_booking. Source: https://docs.getridian.com/developers/tools/reschedule_booking/ Language: en Reviewed: 2026-10-06 This reference is generated from the published tool contract. ## Behavior and boundaries Moves a booking to a new start time as the host. Ridian moves the calendar event and emails the booker. Use a start time returned by find_booking_slots for the booking's appointment type. Overwrites the current time; confirm with the user first. ## Permissions Granted scopes, accounts, calendars and visibility rules limit access. Workspace administrators do not automatically gain access to other users’ accounts. `bookings:write` [Consent and boundaries](https://docs.getridian.com/developers/authentication/) ## Input ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "booking_id": { "type": "string", "minLength": 1, "maxLength": 64, "description": "booking_id from list_bookings." }, "start": { "type": "string", "maxLength": 40 } }, "required": [ "booking_id", "start" ], "additionalProperties": false } ``` ## Output ```json { "$schema": "https://json-schema.org/draft/2020-12/schema", "type": "object", "properties": { "booking_id": { "type": "string" }, "rescheduled": { "type": "boolean" } }, "required": [ "booking_id", "rescheduled" ], "additionalProperties": false } ``` ## Errors and retries Check the tool result for errors.
