Update memory

Updates an existing memory row. Without uploads, send JSON with memory, memoryType, and optional model fields as below. When uploads are present, the endpoint forwards multipart form data similar to Add to memory.

POST/users/update-memory

Request fields

Field	Type	Required	Description
memory	object	Required	The memory record to update—typically the object returned from list or create routes, including its id and current fields.
memoryType	string	Required	Same type you used when creating the record (for example user_memory or organisation_memory). Must be non-empty.
user	object \| string	Optional	Optional JSON object or string whose model fields are merged with the API key owner before the request is sent to Leni.
modelType	string	Optional	Top-level model type, merged into the outbound user. If you set modelId, you should also send modelType.
modelId	string \| null	Optional	Top-level model id, merged into the outbound user when you include it on the body.
noteTitle	string	Optional	Updated title. When you attach files, this is forwarded as an explicit form field alongside the memory JSON.
noteContext	string	Optional	Updated body text. When you attach files, this is forwarded as an explicit form field alongside the memory JSON.
files / filesBase64	array	Optional	Optional file attachments using the same base64 object shape as run-models and add-to-memory (see File uploads). When present, the service forwards multipart form data to Leni.

Example

JSON

{
  "memoryType": "user_memory",
  "memory": {
    "id": "memory-row-id",
    "noteTitle": "Updated title",
    "noteContext": "Updated body…"
  },
  "modelType": "leniq-pro"
}

Optional uploads

JSON only: send memory and related fields in a normal JSON body.
With file bytes: the API forwards multipart fields for noteTitle, noteContext, memory, and one or more files parts.
JSON base64: use files or filesBase64 with the shared structure described in File uploads.

Example with attachment metadata

JSON

{
  "memoryType": "user_memory",
  "memory": {
    "id": "memory-row-id",
    "noteTitle": "Updated title",
    "noteContext": "See the attached policy."
  },
  "modelType": "leniq-pro",
  "noteTitle": "Updated title",
  "noteContext": "See the attached policy.",
  "files": [
    {
      "filename": "policy.pdf",
      "contentType": "application/pdf",
      "contentBase64": "<base64-here>"
    }
  ]
}

Code examples

const res = await fetch(`${process.env.API_BASE}/users/update-memory`, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-Api-Key": process.env.LENI_API_KEY!,
  },
  body: JSON.stringify({
    memoryType: "user_memory",
    memory: {
      id: "memory-row-id",
      noteTitle: "Updated title",
      noteContext: "Updated body…",
    },
    modelType: "leniq-pro",
  }),
});

await res.json();

Pair with list to fetch ids first.
