# Set request headers

HTTP headers allow you to send additional information with your API requests, such as authentication tokens, API version specifications, or content type declarations. Many APIs require specific headers to function properly.

Check your target API's documentation to see which headers you need to include with your requests. You can also [learn more about HTTP headers in general here](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers).

## How to manage request headers

### Add a request header

1. On the custom request screen, click the **Headers** tab.
2. Click **+ Add** to create a new header.
