# How to configure Start node triggers?

In Scenario Builder, each section has a **Start node** — the entry point that defines how and when the section logic runs. Below is an index of instructions for each trigger type.

## Trigger types overview

| Trigger | Purpose | Instruction |
|---------|---------|-------------|
| **Process start** | Manual run, testing, scheduled scenarios | [Configure process start](/en/scenariobuilder/how-to/configure-start-node-process-start.md) |
| **Webhook** | Run on HTTP request (CRM, forms, API) | [Configure webhook](/en/scenariobuilder/how-to/configure-start-node-webhook.md) |
| **Channels** | Run on message in messenger or widget | [Configure channels](/en/scenariobuilder/how-to/configure-start-node-channels.md) |
| **Internal Events** | Run on system event (ticket, new message in ticket, SLA, error) | [Configure internal events](/en/scenariobuilder/how-to/configure-start-node-internal-events.md) |
| **MCP Tool** | Call section from AI assistant (Cursor, Fastline) | [Configure MCP Tool](/en/scenariobuilder/how-to/configure-start-node-mcp-tool.md) |
| **Apps** | Run from an external application — Google Forms responses become tickets | [Receive Google Forms responses](/en/scenariobuilder/how-to/configure-start-node-google-forms.md) |
