Default headers

HTTP is a protocol that web apps use to fetch data from the internet. Everything on your browser is transmitted over HTTP using requests.

Headers are a vital part of these requests. HTTP headers allow clients and servers to talk to each other and pass extra bits of information or instructions. Request headers include additional information sent by the client to the server.

They usually contain instructions about the required data and information about the client. The server can use these headers to customize the response.

Some examples of request headers include:. Authentication and Authorization. Axios is a data fetching package that lets you send HTTP requests using a promise-based HTTP client.

If you want to add headers only to specific request types like GET, you can use the defaults.headers.get property.

This snippet will add the x-rapidapi-key header to all the GET requests. Finally, you can also use request interceptors to add the headers.

HTTP Request Headers

Request Interceptors allow us to modify all the HTTP requests before sending them. We can set an interceptor for the request using the .interceptors.request.use property and specify our headers like this. For more detail, check out our guide on HTTP Interceptors.
