# Install ACPT with Composer

How to install ACPT using Composer

ACPT can be installed using [Composer](https://getcomposer.org/).

### Authorization

The `auth.json` file is made up of a username and password field. The username and password are used by Composer to authenticate to our API with HTTP basic authentication.

The username is the ACPT user email, and the password is the license key.

```json
{
  "http-basic": {
    "dash.acpt.io/composer": {
      "username": "mauro@acpt.io",
      "password": "1234567890"
    }
  }
}
```

Please read more about how Composer handles the authentication for private repositories [here](https://getcomposer.org/doc/articles/authentication-for-private-packages.md).

### Add ACPT Repository <a href="#add-our-repository" id="add-our-repository"></a>

Add our repository to your `composer.json` file:

```json
"repositories": [
    {
        "type":"composer",
        "url":"https://dash.acpt.io/composer"
    }
]
```

### Install the Plugin <a href="#install-the-plugin" id="install-the-plugin"></a>

### Version Constraints <a href="#version-constraints" id="version-constraints"></a>
