# Trigger - Go SDK

> Trigger type definition

<Warning>
  The Go SDK and docs are currently in beta.
  Report issues on [GitHub](https://github.com/OpenRouterTeam/go-sdk/issues).
</Warning>

## Supported Types

### AnthropicInputTokensTrigger

```go lines theme={null}
trigger := components.CreateTriggerInputTokens(components.AnthropicInputTokensTrigger{/* values here */})
```

### AnthropicToolUsesTrigger

```go lines theme={null}
trigger := components.CreateTriggerToolUses(components.AnthropicToolUsesTrigger{/* values here */})
```

## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go lines theme={null}
switch trigger.Type {
	case components.TriggerTypeInputTokens:
		// trigger.AnthropicInputTokensTrigger is populated
	case components.TriggerTypeToolUses:
		// trigger.AnthropicToolUsesTrigger is populated
}
```
