Action fastline_pro
System ID:
action_fastline_pro
Description
Talks to a Fast Line Pro agent: sends a request, keeps conversation context via a constant, optionally files (vision), and blocking / streaming modes. The agent’s model and tools are set in the Fast Line Pro UI (Publish), not in the node JSON.
The response is stored in a constant (completion or save_response).
Events (scenario branches)
| Event | When it occurs |
|---|---|
| (response text) | Success: the action returns the agent’s response text |
| error | Missing agent_name / request / token, timeout, or service error |
On success the branch is the response text itself. For stable branching use the save_response constant and the error branch.
