# Delete an item

`DELETE /v1/memory/collections/{collection}/items/{key}`

## Request

- Base URL: `https://api.zavu.dev`
- URL: `https://api.zavu.dev/v1/memory/collections/{collection}/items/{key}`
- Auth: HTTP bearer

Idempotent: deleting a key that is not there, or a key of a collection that does not exist, still answers `204`. Deletes are never refused for quota reasons.

## Path parameters

- `collection` string, required
- `key` string, required

## Query parameters

- `scope` string: Scope as a query-string value: `contact:<contactId>`, `conversation:<conversationId>`, the literal `project`, or omitted for project scope. Only the SHAPE of the id is validated, never its existence — the partition already carries your project, so an id that matches nothing simply addresses an empty scope rather than returning 404.

## Headers

- `If-Match` string

## Response `204`

Item deleted.

## Other responses

- `400`: Invalid collection name, key, `scope`, or `If-Match`.
- `401`: Unauthorized.
- `409`: `revision_conflict`: the item changed since the revision in `If-Match`. Re-read it and retry.
