# Detach Contact Company

> Detach a contact from its current company

## Overview

This endpoint detaches a contact from its company, leaving it with no company. In the same transaction, the contact's conversions, touchpoints, and visit metadata are re-stamped with a `null` company id, so company-level reports and the [Companies dataset](/data-warehouse/datasets/companies) `company_id` columns in the data warehouse follow immediately.

There is no request body — the contact id in the path is the whole request.

This call is idempotent: calling it on a contact that already has no company returns a normal `200`, not an error.

## Path Parameters

<ParamField path="id" type="integer" required>
  The unique identifier of the contact to detach. Merged profile aliases are automatically resolved to the current canonical contact — the response's `id` is the surviving contact.
</ParamField>

## Response

### Success Response

<ResponseField name="id" type="integer">
  The unique identifier of the contact (after resolving merged-profile aliases).
</ResponseField>

<ResponseField name="company_id" type="null">
  Always `null` after a successful detach.
</ResponseField>

### Error Response

<ResponseField name="message" type="string">
  Error description explaining what went wrong.
</ResponseField>

## Notes

* **Rate Limit**: This endpoint has a limit of **60 requests per minute** per Space. See [Rate Limiting](/introduction/rate-limiting) for details, the same bucket as [Update Contact](/api-reference/endpoint/update-contact).
* **No request body**: the contact id in the path is the whole request.
* **Rows are re-stamped, not just the pivot**: the contact's conversions, touchpoints, and visit metadata are updated to a `null` `company_id` in the same transaction, so company-level reports and the data warehouse [Companies dataset](/data-warehouse/datasets/companies) reflect the detach right away.
* **No-op on an already-detached contact**: calling this on a contact with no company still returns `200` with `company_id: null` — it is not an error.
* **Merged profiles**: If you pass an ID that was merged into another profile, the detach is applied to the canonical (current) profile, and the response's `id` is that canonical id.
* **Behavior after a manual detach depends on company identity mode**: in the default **Auto** mode, the tracker assigns a company to any contact that currently has none, so the contact's next event carrying a business-email domain undoes the detach. In **External ID** mode, the next event carrying a `company_external_id` re-points the contact the same way.
