Building Agents
Designing agents with the visual builder.
Use the visual builder to compose your agent from node types such as conversation, decision, and tool nodes.
Call duration
Runtime settings include Max call duration — how long a single call may run before the agent ends it. Valid values are 1 to 120 minutes; leaving it empty uses the default of 60.
Values outside that range are rejected when you save, with the error code
INVALID_CALL_DURATION. This applies whether you save from the builder or call the API
directly.
If you have an agent configured above 120 minutes from before this limit applied, its calls have always ended at 120 — the limit is enforced when the call runs, not only when you save. Opening that agent in the builder shows the corrected value, which is stored the next time you save.
