# OpenAPI

Yes, yes and yes, HTTL supports the OpenAPI specification.

**Note**  
HTTL supports Swagger 2.x and OpenAPI 3.x specifications.

To integrate an OpenAPI specification file, simply add the @spec directive with the URL pointing to your OpenAPI specification.

### Syntax  
```
@spec: <url>
```

### Example  
```
@spec: https://httl.dev/api/spec.json

get <type '/' or press Ctrl+Space | Option+Esc to see the list of available paths>
```

### IntelliSense  
HTTL can autocomplete the paths and methods from the OpenAPI specification file.

* * *

HTTL can automatically generate the request body based on the OpenAPI specification.

To utilize this feature:

- Press the spacebar after the URL.
- HTTL will generate the request body.
- Accept the generated body by pressing the Tab key.

* * *

You can also use `Ctrl+Space | Option+Esc` to see the list of available body schema.

💡

**Tip**  
This feature is particularly useful when the IDE’s IntelliSense conflicts with other plugins, especially Copilot’s autogeneration.

**Note**  
There is no IntelliSense for the body shema yet but it’s coming soon.
