# Delete Portfolio

> Delete a portfolio and its membership associations

<Snippet file="portfolios/access.mdx" />

See [portfolio limits and references](/guides/portfolios) for current caps and
`external_ref` semantics.

## Overview

Requires an `Idempotency-Key` header. Deleting a portfolio removes its membership
associations and references; the underlying trademark records remain available.
A mark stops counting toward your managed-marks allowance only when none of your
organization's portfolios contains it.

## Response

A successful deletion returns HTTP 200 with `id`, `object: "portfolio"`, and
`deleted: true`.

## Errors

An unknown portfolio or one belonging to another organization returns 404. Active
webhook references block deletion with 409 `portfolio_in_use`, which lists the
referencing endpoints in `endpoint_ids`.
