# Save a memory file

PUT https://api.cloudraker.com/agents/{agentRef}/memory/files
Content-Type: application/json

Creates or replaces one file. `expectBlob` is the blob you read (null for a new file), so a concurrent edit answers 409 instead of being overwritten.

Reference: https://docs.cloudraker.com/workspace/api/workspace-agents/put-agent-memory-file

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `agentRef` (string, required)

### Body (application/json)

This endpoint expects an object.

- `path` (string, required)
- `content` (string, required)
- `expectBlob` (string, required, nullable) — The blob you read, or null to create a new file. Stale values answer 409.
- `message` (string, optional)

## Response

### 200

Nothing changed; the unchanged head

- `data` (AgentsAgentRefMemoryFilesPutResponsesContentApplicationJsonSchemaData, required)

### 201

The new version

- `data` (AgentsAgentRefMemoryFilesPutResponsesContentApplicationJsonSchemaData, required)

## Errors

### 400 Bad Request Error

Validation Error

- `success` (boolean, required)
- `error` (list of any, required)
- `data` (any, required)

### 403 Forbidden Error

`personal_account_required` — only the owner may open this memory.

- `error` (string, required) — The sentence a human reads.
- `error_code` (string, required) — The stable snake_case branch key.
- `issues` (list of ErrorEnvelopeIssuesItems, optional) — Per-field detail, present only on a validation failure.

### 404 Not Found Error

`memory_not_available` — this memory does not exist for you.

- `error` (string, required) — The sentence a human reads.
- `error_code` (string, required) — The stable snake_case branch key.
- `issues` (list of ErrorEnvelopeIssuesItems, optional) — Per-field detail, present only on a validation failure.

### 409 Conflict Error

`expect_failed` (`paths`) — the file changed since you read it; `stale_parent` or `conflict` — the history moved.

- `error` (string, required) — The sentence a human reads.
- `error_code` (string, required) — The stable snake_case branch key.
- `issues` (list of ErrorEnvelopeIssuesItems, optional) — Per-field detail, present only on a validation failure.

### 422 Unprocessable Entity Error

`lint_failed` — `violations` lists each file rule the change broke.

- `error` (string, required) — The sentence a human reads.
- `error_code` (string, required) — The stable snake_case branch key.
- `issues` (list of ErrorEnvelopeIssuesItems, optional) — Per-field detail, present only on a validation failure.

## Types

### AgentsAgentRefMemoryFilesPutResponsesContentApplicationJsonSchemaData

- `sha` (string, required, nullable)
- `branch` (string, required)
- `changed` (double, required) — How many files the version changed.

### ErrorEnvelopeIssuesItems

- `path` (string, required)
- `code` (string, required)
- `message` (string, required)
