POST

Calendar.Update

Alias of Calendar.Edit. Update an existing calendar appointment in the appointments table.

Permissions

User must be logged in with a valid bearer token.
The user must be from the same company domain as the request Host (call the API on that account subdomain or allowed custom domain). A token from another company returns success=0, error user_not_in_company.
Returned or changed records are limited by the user permissions, team access, folder access, and account settings.

Action

Updates the requested Calendar record after validating permissions and input fields.

Push Service

No push is sent because this function only reads data or returns helper information.

Automation

No automation is run for this function.

Special Instructions

Send the bearer token on protected calls with Authorization: Bearer YOUR TOKEN.
On a company subdomain (e.g. https://{user_domain}.bull36.com) the user must match that Host — Login and protected APIs reject another company with success=0, error user_not_in_company. On a main brand host (bull36.com, biz1.co.il, mastrocrm.com, …) the company domain gate is skipped.
Send parameters as POST body fields exactly as documented.
Send date/time values in UTC Y-m-d H:i:s format when a date or datetime field is used.

Required Parameters

Name	Type	Sample	Explanation
`appointment_id` post	int	`9001`	Appointment id to update.
`title` post	string	`test add event`	Event title.
`date` post	date	`2026-07-29`	Appointment date Y-m-d. Send date filters and date values as UTC Y-m-d H:i:s when the route accepts date/time; date-only table columns store the Y-m-d date part.
`start_time` post	time	`04:00`	Start time H:i. Send time values as H:i:s. If the route also has a date field, send that date as UTC Y-m-d H:i:s.

Optional Parameters

Name	Type	Sample	What it gives
`end_time` post	time	`04:30`	End time H:i. Send time values as H:i:s. If the route also has a date field, send that date as UTC Y-m-d H:i:s.
`duration` post	int	`30`	Duration minutes.
`appoinment_color` post	string	`red`	Color label.
`customer_id` post	int	`108545`	Optional customer id.

Authentication

Send the bearer token returned by Login in the request header. The user must be from the same company domain as this Host — a token from another company is rejected (user_not_in_company).
