Media Gateway RESTful APIs require server-side authentication. Use the same
authentication scheme described in the product reference and pass the generated
`Authorization` header with each request.

## HTTP Basic authentication [#http-basic-authentication]

Every time you send an HTTP request, pass a credential in the `Authorization`
request header.

Basic authentication is an HTTP authentication scheme. To use it, send requests
with an `Authorization` header that contains `Basic`, followed by a space and a
base64-encoded `username:password` string.

```text
Authorization: Basic ZGVtbzpwQDU1dzByZA==
```

## HTTP HMAC authentication [#http-hmac-authentication]

Every time you send an HTTP request, pass an API key in the `Authorization`
request header.

```text
Authorization: 123
```
