## Preview RPC **post** `/agents/{agent_id}/deployments/{deployment_id}/rpc` Send an RPC request to a specific deployment (for preview testing). ### Path Parameters - `agent_id: string` - `deployment_id: string` ### Body Parameters - `method: "event/send" or "task/create" or "message/send" or 2 more` - `"event/send"` - `"task/create"` - `"message/send"` - `"task/cancel"` - `"task/interrupt"` - `params: object { name, params, task_metadata } or object { task_id, task_name } or object { task_id, task_name } or 2 more` The parameters for the agent RPC request - `CreateTaskRequest object { name, params, task_metadata }` - `name: optional string` Optional human-readable name for the task. When set it must be globally unique. task/create is get-or-create by name: reusing an existing name returns the existing task (with its prior history) instead of creating a new one, so omit name (or make it unique, e.g. by appending a UUID) whenever each call should produce a fresh task. - `params: optional map[unknown]` The parameters for the task. On a get-or-create by name, providing params overwrites the existing task's params (it is not a pure read). - `task_metadata: optional map[unknown]` Caller-provided metadata to persist on the task row. Only applied at task creation; ignored if a task with this name already exists. Forwarded to the agent inside the ACP payload for backward compatibility. - `CancelTaskRequest object { task_id, task_name }` - `task_id: optional string` The ID of the task to cancel.
