## Redact a memory version **post** `/v1/memory_stores/{memory_store_id}/memory_versions/{memory_version_id}/redact` Redact a memory version ### Path Parameters - `memory_store_id: string` - `memory_version_id: string` ### Header Parameters - `"anthropic-beta": optional array of AnthropicBeta` Optional header to specify the beta version(s) you want to use. - `string` - `"message-batches-2024-09-24" or "prompt-caching-2024-07-31" or "computer-use-2024-10-22" or 22 more` - `"message-batches-2024-09-24"` - `"prompt-caching-2024-07-31"` - `"computer-use-2024-10-22"` - `"computer-use-2025-01-24"` - `"pdfs-2024-09-25"` - `"token-counting-2024-11-01"` - `"token-efficient-tools-2025-02-19"` - `"output-128k-2025-02-19"` - `"files-api-2025-04-14"` - `"mcp-client-2025-04-04"` - `"mcp-client-2025-11-20"` - `"dev-full-thinking-2025-05-14"` - `"interleaved-thinking-2025-05-14"` - `"code-execution-2025-05-22"` - `"extended-cache-ttl-2025-04-11"` - `"context-1m-2025-08-07"` - `"context-management-2025-06-27"` - `"model-context-window-exceeded-2025-08-26"` - `"skills-2025-10-02"` - `"fast-mode-2026-02-01"` - `"output-300k-2026-03-24"` - `"user-profiles-2026-03-24"` - `"advisor-tool-2026-03-01"` - `"managed-agents-2026-04-01"` - `"cache-diagnosis-2026-04-07"` ### Returns - `BetaManagedAgentsMemoryVersion object { id, created_at, memory_id, 10 more }` A `memory_version` object: one immutable, attributed row in a memory's append-only history. Every non-no-op mutation to a memory produces a new version. Versions belong to the store (not the individual memory) and persist after the memory is deleted. Retrieving a redacted version returns 200 with `content`, `path`, `content_size_bytes`, and `content_sha256` set to `null`; branch on `redacted_at`, not HTTP status. - `id: string` Unique identifier for this version (a `memver_...` value). - `created_at: string` A timestamp in RFC 3339 format - `memory_id: string` ID of the memory this version snapshots (a `mem_...` value). Remains valid after the memory is deleted; pass it as `memory_id` to [List memory versions](/docs/en/api/beta/memory_stores/memory_versions/list) to retrieve the full lineage including the `deleted` row. - `memory_store_id: string` ID of the memory store this version belongs to (a `memstore_...` value). - `operation: BetaManagedAgentsMemoryVersionOperation` The kind of mutation a `memory_version` records. Every non-no-op mutation to a memory appends exactly one version row with one of these values. - `"created"` - `"modified"` - `"deleted"` - `type: "memory_version"` - `"memory_version"` - `content: optional string` The memory's UTF-8 text content as of this version. `null` when `view=basic`, when `operation` is `deleted`, or when `redacted_at` is set. - `content_sha256: optional string` Lowercase hex SHA-256 digest of `content` as of this version (64 characters). `null` when `redacted_at` is set or `operation` is `deleted`. Populated regardless of `view` otherwise. - `content_size_bytes: optional number` Size of `content` in bytes as of this version. `null` when `redacted_at` is set or `operation` is `deleted`. Populated regardless of `view` otherwise. - `created_by: optional BetaManagedAgentsActor` Identifies who performed a write or redact operation. Captured at write time on the `memory_version` row. The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible. Look up session provenance separately via the [Sessions API](/docs/en/api/sessions-retrieve). - `BetaManagedAgentsSessionActor object { session_id, type }` Attribution for a write made by an agent during a session, through the mounted filesystem at `/mnt/memory/`. - `session_id: string` ID of the session that performed the write (a `sesn_...` value). Look up the session via [Retrieve a session](/docs/en/api/sessions-retrieve) for further provenance. - `type: "session_actor"` - `"session_actor"` - `BetaManagedAgentsAPIActor object { api_key_id, type }` Attribution for a write made directly via the public API (outside of any session). - `api_key_id: string` ID of the API key that performed the write. This identifies the key, not the secret. - `type: "api_actor"` - `"api_actor"` - `BetaManagedAgentsUserActor object { type, user_id }` Attribution for a write made by a human user through the Anthropic Console. - `type: "user_actor"` - `"user_actor"` - `user_id: string` ID of the user who performed the write (a `user_...` value). - `path: optional string` The memory's path at the time of this write. `null` if and only if `redacted_at` is set. - `redacted_at: optional string` A timestamp in RFC 3339 format - `redacted_by: optional BetaManagedAgentsActor` Identifies who performed a write or redact operation. Captured at write time on the `memory_version` row. The API key that created a session is not recorded on agent writes; attribution answers who made the write, not who is ultimately responsible. Look up session provenance separately via the [Sessions API](/docs/en/api/sessions-retrieve). ### Example ```http curl https://api.anthropic.com/v1/memory_stores/$MEMORY_STORE_ID/memory_versions/$MEMORY_VERSION_ID/redact \ -X POST \ -H 'anthropic-version: 2023-06-01' \ -H 'anthropic-beta: managed-agents-2026-04-01' \ -H "X-Api-Key: $ANTHROPIC_API_KEY" ``` #### Response ```json { "id": "id", "created_at": "2019-12-27T18:11:19.117Z", "memory_id": "memory_id", "memory_store_id": "memory_store_id", "operation": "created", "type": "memory_version", "content": "content", "content_sha256": "content_sha256", "content_size_bytes": 0, "created_by": { "session_id": "x", "type": "session_actor" }, "path": "path", "redacted_at": "2019-12-27T18:11:19.117Z", "redacted_by": { "session_id": "x", "type": "session_actor" } } ```
