<Info>
These v4 endpoints operate on extracted memories (not raw documents). SDK support coming soon — use fetch or cURL for now.

For document management (list, get, update, delete), see [Document Operations](/document-operations).

## Forget Memory

Soft-delete a memory — excluded from search results but preserved in the system. Use this when you might want to restore later.

<Tabs>
  <Tab title="fetch">
    ```typescript
    await fetch("https://api.supermemory.ai/v4/memories/mem_abc123/forget", {
      method: "POST",
      headers: {
        "Authorization": `Bearer ${API_KEY}`
      }
    });
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X POST "https://api.supermemory.ai/v4/memories/mem_abc123/forget" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY"
    ```
  </Tab>
</Tabs>

The memory will no longer appear in search results but remains in the database.

## Update Memory (Versioned)

Update a memory by creating a new version. The original is preserved with `isLatest=false`.

<Tabs>
  <Tab title="fetch">
    ```typescript
    await fetch("https://api.supermemory.ai/v4/memories", {
      method: "PATCH",
      headers: {
        "Authorization": `Bearer ${API_KEY}`,
        "Content-Type": "application/json"
      },
      body: JSON.stringify({
        // Identify by ID or content
        id: "mem_abc123",
        // content: "Original content to match",

        newContent: "Updated content goes here",
        metadata: {
          tags: ["updated"]
        }
      })
    });
    ```
  </Tab>
  <Tab title="cURL">
    ```bash
    curl -X PATCH "https://api.supermemory.ai/v4/memories" \
      -H "Authorization: Bearer $SUPERMEMORY_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{
        "id": "mem_abc123",
        "newContent": "Updated content goes here",
        "metadata": {"tags": ["updated"]}
      }'
    ```
  </Tab>
</Tabs>
