# Create Conversation

> Create a new conversation in a workspace

```
POST /openapi/memorylake/api/v3/workspaces/{workspaceId}/memories/conversations
```

Creates a new conversation within a workspace. A conversation groups related messages together so MemoryLake can extract structured facts from the exchange. You must attach exactly one read-write project via `rw_project_ids` — this is the project where extracted facts and memory are stored.

<Note>
  **Permission required:** `workspace:conv_create` (plus `project:mem_add` and `project:doc_add` on the specified project)
</Note>

### Path Parameters

<ParamField path="workspaceId" type="string" required>
  Workspace identifier
</ParamField>

### Request Body

<ParamField body="custom_id" type="string" required>
  Caller-defined unique identifier. Use this to correlate the conversation with records in your own system.
</ParamField>

<ParamField body="kind" type="string" required>
  Conversation kind: `DIRECT` (one-on-one) or `GROUP` (multi-participant).
</ParamField>

<ParamField body="rw_project_ids" type="array" required>
  Read-write project(s) the conversation reads context from and writes facts to. Exactly one project ID is required.
</ParamField>

<ParamField body="name" type="string">
  Display name for the conversation
</ParamField>

<ParamField body="metadata" type="object">
  Arbitrary key-value metadata to attach to the conversation
</ParamField>

<ParamField body="actor_ids" type="array">
  IDs of actors participating in the conversation. Each ID should reference an actor you have previously created.
</ParamField>
