How to send a text message#

Before adding the green-api package, you need to install composer (php dependency manager).

composer require green-api/whatsapp-api-client-php

require './vendor/autoload.php';

You may see the full example at: sendTextMessage.php

$greenApi = new GreenApiClient( ID_INSTANCE, API_TOKEN_INSTANCE );

Please note that keys can be obtained from environment variables:

<?php
require './vendor/autoload.php';

define( "ID_INSTANCE", getenv("ID_INSTANCE" ));
define( "API_TOKEN_INSTANCE", getenv("API_TOKEN_INSTANCE") );

$result = $greenApi->sending->sendMessage('11001234567@c.us', 'Message text');

php -S localhost:8080
