# Delete a memory store

`beta.memory_stores.delete(memory_store_id, **kwargs) -> BetaManagedAgentsDeletedMemoryStore`

**DELETE** `/v1/memory_stores/{memory_store_id}`

Delete a memory store

## Parameters

- `memory_store_id: String` (path parameter)

  ID of the memory store to permanently delete (a `memstore_...` identifier). Required. Deletion cascades to all memories and memory versions in the store and cannot be undone.

- `betas: Array[AnthropicBeta]` (header parameter)

  This endpoint is in beta: requests must send `agent-memory-2026-07-22` or `managed-agents-2026-04-01` in this header.

- `workspace_id: String` (header parameter)

  Optional header to select the Workspace for this request. The value is a Workspace ID (for example, `wrkspc_011CZkZaBF1tNoB5wlCeusgy`).

  Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

## Returns

- `class BetaManagedAgentsDeletedMemoryStore`

  Confirmation that a `memory_store` was deleted.

  - `type: :memory_store_deleted`

  - `id: String`

    ID of the deleted memory store (a `memstore_...` identifier). The store and all its memories and versions are no longer retrievable.

## Example

```ruby
require "anthropic"

anthropic = Anthropic::Client.new(api_key: "my-anthropic-api-key")

beta_managed_agents_deleted_memory_store = anthropic.beta.memory_stores.delete("memory_store_id")

puts(beta_managed_agents_deleted_memory_store)
```

### Response (200)

```json
{
  "id": "id",
  "type": "memory_store_deleted"
}
```
