SendinBlue, guzzle: Connection refused-CodePudding

I'm working on a project where I need to send transactional emails to my clients.

The following error appears when sending the request. I use SendinBlue V3 SDK.

Exception when calling TransactionalEmailsApi->sendTransacEmail: Connection refused for URI
https://api.sendinblue.com/v3/smtp/email

My method code:

$config = Configuration::getDefaultConfiguration()->setApiKey('api-key', 'secret');
$apiInstance = new TransactionalEmailsApi(
    new GuzzleHttp\Client([
        'base_uri' => 'https://uplann.online'
    ]),
    $config
);
$sendSmtpEmail = new SendSmtpEmail();
$sendSmtpEmail['to'] = [
    [
        'email' => $parameters['mail'],
        'name' => $parameters['user'],
    ]
];
$sendSmtpEmail['templateId'] = 3;
$sendSmtpEmail['params'] = [
    'FIRSTNAME' => $parameters['user'],
    'LASTNAME' => $parameters['verification_code'],
];

try {
    $result = $apiInstance->sendTransacEmail($sendSmtpEmail);
    print_r($result);
} catch (ConnectException $e) {
    echo 'Exception when calling TransactionalEmailsApi->sendTransacEmail: ', $e->getMessage(), PHP_EOL;
}

Did you configure correctly your https client with Guzzle ? If not connecting, then you can check if any other exceptions are thrown. You have a great inventory of them in the Guzzle documentation : https://docs.guzzlephp.org/en/stable/quickstart.html#exceptions

. \RuntimeException
└── TransferException (implements GuzzleException)
    ├── ConnectException (implements NetworkExceptionInterface)
    └── RequestException
        ├── BadResponseException
        │   ├── ServerException
        │   └── ClientException
        └── TooManyRedirectsException

In your case, it is a ConnectException. Try to get more information about it.

Why ConnectException are thrown usually ? When you can not connect.

When you can not connect ? When you are not using correct endpoint url, have not configured your HTTP client to use HTTPS protocol, not using the endpoint accordingly to its specs you'll find inside official documentation.

You can look the official tutorial too : https://developers.sendinblue.com/docs/send-a-transactional-email

You can use the github.com sendinblue official repository too with the php api well described : https://github.com/sendinblue/APIv3-php-library
