# OutputMessageItemContent - Go SDK

> OutputMessageItemContent 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

### ResponseOutputText

```go lines theme={null}
outputMessageItemContent := components.CreateOutputMessageItemContentOutputText(components.ResponseOutputText{/* values here */})
```

### OpenAIResponsesRefusalContent

```go lines theme={null}
outputMessageItemContent := components.CreateOutputMessageItemContentRefusal(components.OpenAIResponsesRefusalContent{/* values here */})
```

## Union Discrimination

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

```go lines theme={null}
switch outputMessageItemContent.Type {
	case components.OutputMessageItemContentTypeOutputText:
		// outputMessageItemContent.ResponseOutputText is populated
	case components.OutputMessageItemContentTypeRefusal:
		// outputMessageItemContent.OpenAIResponsesRefusalContent is populated
	default:
		// Unknown type - use outputMessageItemContent.GetUnknownRaw() for raw JSON
}
```
