# Request Header Parser
freeCodeCamp - Back End Development and APIs | Project: Request Header Parser
# Summary
Create a Request Header Parser api that when you make a request to `/api/whoami` it should return a JSON object with:
- IP address in the `ipaddress` key.
- Preferred language in the `language` key.
- Software in the `software` key.
**[Learn more about the Project Task.](https://www.freecodecamp.org/learn/back-end-development-and-apis/back-end-development-and-apis-projects/request-header-parser-microservice)**
### Implementation
- Created a TypeScript + Express API
- Create a route called `/api/whoami` that retrieves the following:
- From the `req` object, we can get the **ip address**. The IP Address is a unique address that identifies a device on the internet or a local network.
- From the `headers` object, we can get:
- the **accept-language** header is used by a client (typically a web browser) to communicate to the server the preferred languages for content. The server can then use this information to provide content in the most suitable language for the user.
- the **user-agent header** is a standard HTTP header included in the request sent by a user agent, typically a web browser or a similar client, to provide information about the user agent (i.e., the software and device) making the request.
#### Code implementation
```
const { ip, headers } = req;
const ipaddress = ip;
const language = headers['accept-language'];
const software = headers['user-agent'];
const responseObject = {
ipaddress,
language,
software
};
```
