EDN saves the new text as a new USER_CONFIRMED memory and keeps the old version in the history. Returns the new memory: use its `id` from now on. USER_STATED, USER_CONFIRMED, AI_INFERRED and AI_GENERATED memories can be edited; documents and conversation turns return 409. Use this endpoint when a user fixes a memory directly, for example in a memory settings screen. EDN never overwrites a memory: it saves the new text as a new version and keeps the old one in the history. ## What EDN does 1. Saves the new text as a new `USER_CONFIRMED` memory with a new ID. 2. Marks the old memory as replaced, so SIPs stop using it. 3. Keeps the old version in the memory's [history](https://docs.tensorpro.ai/api-reference/memory-record-history.md). ## Required headers | Header | Value | Description | | - | - | - | | `Authorization` | `Bearer YOUR_API_KEY` | Your EDN API key. Create keys in the [Console](https://docs.tensorpro.ai/console/api-keys.md). See [Authentication](https://docs.tensorpro.ai/authentication.md) | | `Content-Type` | `application/json` | The request body is JSON | ## Request ### Path parameters | Parameter | Type | Description | | - | - | - | | `record_id` | string | Identifier for the current version of the memory to edit | ### Body | Field | Type | Required | Description | | - | - | - | - | | `content` | string | Yes | The corrected text for the memory. 1 to 1,000 characters | ```bash cURL theme={"theme":"github-light"} curl -X PATCH "https://api.tensorpro.ai/api/v1/memory/records/8f0d2c61-5b7e-4a39-9c1e-2d4f6a8b0e17" \ -H "Authorization: Bearer $EDN_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "content": "Tom manages the website project." }' ``` ```python Python theme={"theme":"github-light"} import os import requests resp = requests.patch( "https://api.tensorpro.ai/api/v1/memory/records/8f0d2c61-5b7e-4a39-9c1e-2d4f6a8b0e17", headers={"Authorization": f"Bearer {os.environ['EDN_API_KEY']}"}, json={ "content": "Tom manages the website project." }, ) resp.raise_for_status() print(resp.json()) ``` ```javascript JavaScript theme={"theme":"github-light"} const resp = await fetch("https://api.tensorpro.ai/api/v1/memory/records/8f0d2c61-5b7e-4a39-9c1e-2d4f6a8b0e17", { method: "PATCH", headers: { Authorization: `Bearer ${process.env.EDN_API_KEY}`, "Content-Type": "application/json", }, body: JSON.stringify({ "content": "Tom manages the website project." }), }); console.log(await resp.json()); ``` ## Response ```json 200 OK theme={"theme":"github-light"} { "id": "1b3d5f7a-9c2e-4a6b-8d0f-2e4a6c8e0b1d", "content_summary": "Tom manages the website project.", "full_text": "Tom manages the website project.", "provenance": "USER_CONFIRMED", "domain": "factual", "status": "current", "created_at": "2026-11-11T09:12:44+00:00", "project_id": null, "session_id": "chat-42", "source_id": null, "supersedes": "8f0d2c61-5b7e-4a39-9c1e-2d4f6a8b0e17", "superseded_by": null, "event_date": null, "document_date": "2026-11-10T04:43:25+00:00" } ``` Returns the new version of the memory, with the same fields as [Get a memory](https://docs.tensorpro.ai/api-reference/get-memory-record.md). The most useful ones: | Field | Type | Description | | - | - | - | | `id` | string | Identifier for the new version. Use it from now on | | `provenance` | string | Always `USER_CONFIRMED` | | `status` | string | Always `current` | | `supersedes` | string | Identifier for the version you edited | ## Important behavior * **The edited memory gets a new ID.** The old ID still works with [Get a memory](https://docs.tensorpro.ai/api-reference/get-memory-record.md) and history. * **Only current versions can be edited.** Editing a replaced or deleted version returns `404`. * **`USER_STATED`, `USER_CONFIRMED`, `AI_INFERRED` and `AI_GENERATED` memories can be edited.** Documents (`DOCUMENT_VERIFIED`) and conversation turns (`ROUND`) return `409`. ## Errors | Status | Code | When | | - | - | - | | `401` | `UNAUTHORIZED` | The API key is missing, invalid or revoked | | `404` | `NOT_FOUND` | The memory doesn't exist, was deleted, was already replaced, or isn't yours | | `409` | `CONFLICT` | The memory is a document, a conversation turn or system-derived, so it can't be edited | | `422` | `VALIDATION_ERROR` | `content` is missing, empty or longer than 1,000 characters | | `429` | `RATE_LIMITED` | Per-minute limit reached. Retry after `Retry-After` seconds | | `500` | `INTERNAL_ERROR` | Something failed on EDN's side. Retry later | See [Error handling](https://docs.tensorpro.ai/reference/errors.md). ```json 200 theme={"theme":"github-light"} { "id": "1b3d5f7a-9c2e-4a6b-8d0f-2e4a6c8e0b1d", "content_summary": "Tom manages the website project.", "full_text": "Tom manages the website project.", "provenance": "USER_CONFIRMED", "domain": "factual", "status": "current", "created_at": "2026-11-11T09:12:44+00:00", "project_id": null, "session_id": "chat-42", "source_id": null, "supersedes": "8f0d2c61-5b7e-4a39-9c1e-2d4f6a8b0e17", "superseded_by": null, "event_date": null, "document_date": "2026-11-10T04:43:25+00:00" } ``` ## OpenAPI ````yaml patch /api/v1/memory/records/{record_id} openapi: 3.1.0 info: title: EDN Memory Engine version: 0.1.0 servers: - description: EDN evaluation endpoint url: https://api.tensorpro.ai security: - EDNApiKey: [] paths: /api/v1/memory/records/{record_id}: patch: summary: Edit a memory description: >- Change what a memory says.
