POST

Categories.Delete

Hard-delete a product category. Alias of Categories.Remove.

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

Removes the requested Categories record when the user has permission.

Push Service

Pushes event categories.deleted to users who should see this change.

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.

Required Parameters

Name	Type	Sample	Explanation
`category_id` post	int	`123`	Category id. Aliases: id, update_id, data_id, cat_id.

Optional Parameters

No optional body parameters are defined for this function.

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).
