The API supports Basic Authentication for web requests. When connecting to the API via a command line the API credentials must be passed as parameters. See Using the Command Line Interface for more information on connecting to the API via command line. 

RewriteEngine on
...
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

Connecting

There are a number of ways to connect to the API. Choose the option that best fits your environment.

Remotely

If running PHP-FPM, set CGIPassAuth On in your .htaccess, or within your httpd.conf like the example:

    <FilesMatch \.php$>
        CGIPassAuth On
        SetHandler proxy:unix:/var/php-fpm/166630281728629.sock|fcgi://127.0.0.1
    </FilesMatch>

Connecting

There are a number of ways to connect to the API. Choose the option that best fits your environment.

Remotely

To connect remotely, first determine the URL of the API for your installation. The default path is http://yourdomain.com/installpath/api/. Where yourdomain.com is the domain you've installed Blesta in, and installpath is the path to Blesta. If your server does not support .htaccess then the URL should To connect remotely, first determine the URL of the API for your installation. The default path is http://yourdomain.com/installpath/api/. Where yourdomain.com is the domain you've installed Blesta in, and installpath is the path to Blesta. If your server does not support .htaccess then the URL should instead appear as http://yourdomain.com/installpath/index.php/api/. 

...

<?php
require_once "blesta_api.php";

$user = "username";
$key = "key";
$url = "https://yourdomain.com/installpath/api/";

$api = new BlestaApi($url, $user, $key);

$response = $api->get("users", "get", array('user_id' => 1));

print_r($response->response());
print_r($response->errors());
?>

curl https://yourdomain.com/installpath/api/users/get.json?user_id=1 -u username:key

...

php index.php api/users/get.json -u USER -k KEY -m GET -p '"user_id=1'"

Within the Blesta environment

If you're working with or have created code within the Blesta environment, there's no need to use the API at all. All of the methods available in the API are first and foremost available to Blesta, in the form of models. To use these models, simply load the model within your environment.

// from somewhere in your controller...
$this->uses(array("ModelName"));

// Now invoke it
$this->ModelName->someMethod($param1, $param2);

// from any other class...
Loader::loadModels($this, array("ModelName"));

// Now invoke it
$this->ModelName->someMethod($param1, $param2);

...

The API encourages the proper use of GET, POST, PUT, and DELETE when interacting with the API. For all POST requests the API will pass only post parameters to the requested resource. For PUT only put parameters will be passed. Similarly, for all GET and DELETE requests, the API will pass only get parameters to the requested resource.

POST

POST

Use POST requests when creating new records. For example, when Use POST requests when creating new records. For example, when adding a new user record via api/users/add.json.
