POST

Projects.ColumnsDelete

Delete a custom project board column and move affected missions to a replacement column when sent. Default columns (To Do and similar, source=default / can_delete=false) cannot be deleted, same as the dashboard.

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

Runs the Projects.ColumnsDelete function and returns JSON.

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.

Required Parameters

Name	Type	Sample	Explanation
`data_id` post	int\|string	`0`	Custom column JSON index from ColumnsList. Do not send default_0; default columns cannot be deleted.

Optional Parameters

Name	Type	Sample	What it gives
`new_column_name` post	string	`to_do`	Replacement column for existing missions.
`data_value_for_gChart` post	string	`qa`	Gantt chart column value when deleting a chart-only column.

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).
