# Start The **Start Event** defines the **entry point** of a business process.\ It specifies **how and when a process instance is created and begins execution**. In its simplest form, a Start Event is triggered **manually** to initiate the process. However, **ONEWEB Process Designer** also supports additional event triggers that allow processes to be started **automatically**, based on specific conditions or system events. *** ### Purpose of Start Event The Start Event is used to: * Mark the **beginning of a process flow** * Define the trigger that creates a new process instance * Control how the process is invoked (manual or automatic) Every valid process must contain **at least one Start Event**. *** ### Types of Start Events #### Manual Start Event * Triggered explicitly by a user or system action * Commonly used when a process is started on demand * Acts as the default Start Event in most processes *** #### Automatic / Trigger‑Based Start Events In addition to manual triggers, Process Designer provides other **event‑based start mechanisms** that can automatically initiate a process. These triggers can be used to: * Start a process when a specific condition occurs * React to system events * Trigger downstream activities automatically > These advanced event triggers are described in detail in the following sections. *** ### Usage Guidelines * Every process must start with a **Start Event** * A process may have **multiple Start Events** if different triggers are required * Use clear naming to indicate how the process is initiated * Avoid complex logic at the Start Event—use activities and gateways instead * Ensure that each Start Event leads to a valid execution path *** ### Summary The **Start Event** defines the **starting point and trigger mechanism** of a process. Key points: * Mandatory component in every process * Can be triggered manually or automatically * Defines how a process instance is created * Supports extensibility through additional event triggers Understanding and correctly configuring Start Events ensures that processes are **initiated reliably and predictably** within ONEWEB Process Designer. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
