Asynchronous Execution

Start Asynchronous Execution

post

Starts an asynchronous execution of a published Chatbot (Chatflow or Workflow). This is ideal for long-running tasks. The API queues the job and immediately returns an execution_id and tracking URLs, allowing you to check the status later without keeping the connection open.
