# Delete a custom data column from campaign contacts

`DELETE /campaigns/call/{campaignscalllistuuid}/numbers/columns`

Removes a custom column from all contacts in a campaign's call queue. The column is deleted from the `social_data` field of every contact's `json_csv_infos`. The column name must exist in `social_data` — built-in fields (`firstname`, `lastname`, `company`) cannot be deleted. This operation is logged in the campaign's audit log (see `GET .../logs`).

**Permission:** No specific permission required. A valid API key is sufficient.
