Trigger
The starting node of an automated workflow, acting as an event listener that waits for preset conditions to be met before launching the entire pipeline. It is divided into three categories: event-driven, time-driven, and state-change-driven.
Core Facts
Automations are the triggering mechanism of the loop, which can be time-based triggers or event-driven triggers.
n8n triggers fall into two major categories: polling-type (such as scheduled triggers) and event-type (such as Webhook triggers and form submission triggers).
The orchestration patterns of production-grade AI agents can be distilled into four types: cross-system multi-step workflow orchestration, policy-constrained action execution, anomaly handling and data validation, and high-concurrency classification and routing.

Coze's trigger feature takes effect only for the Feishu channel; only by publishing the agent to Feishu can trigger tasks be executed automatically and results written to Feishu sheets or documents.
Before wiring up triggers, one should first list every write the system makes; this is the key to the design.
Triggers in event-driven architectures cannot distinguish write origin from semantics, which is their inherent limitation.
Smarter trigger-based filtering approaches (such as filtering by who made the change or checking timestamps) break down when the next write path appears.
Event-driven triggers can process messages as soon as they arrive, whereas scheduled polling has a latency window.
The three basic building blocks of workflow automation are Trigger, Logic and Action.
The key difference between a trigger and an ordinary node is that a trigger does not need upstream input, but is instead awakened by an external event.
An automated workflow usually starts with a trigger, after which an AI node can be connected to process content, then connected to a spreadsheet or data storage, and finally ends with a notification.
n8n triggers fall into two major categories: polling-type (such as scheduled triggers) and event-type (such as Webhook triggers and form submission triggers).
Each n8n workflow has one and only one trigger node, which is the sole entry point of the workflow.
