> Base URL and Authentication

## Base URL

All requests contain the following base URL:

```cli theme={null}
https://api.amisend.com
```

## API Key

Amisend API keys are used to authenticate API requests. You can find your API keys in the [Amisend dashboard](https://amisend.com/api-keys).

## Authentication

To authenticate you need to add an Authorization header with the contents of the header being Bearer ami\_xxxxxxxxx where ami\_xxxxxxxxx is your [API Key](https://amisend.com/api-keys).

```cli theme={null}
Authorization: Bearer ami_xxxxxxxxx
```
