I do not understand how to configure the REST API Sinch with PHP

Question

I am very new using cURL in PHP, I would like to use this API to send SMS but when I do all the tests I get the following error:

HTTP/1.1 400 Bad Request Content-Length: 0 X-Application-Context: application:production:8080

I have reviewed my code and I do not understand what is really happening:

$data=array('from' => '506712xxxx', 'to' => '50671xxxx', 'body' => 'Hola este es un mensaje de prueba' );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://sms.api.sinch.com/xms/v1/xxxxx/batches");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        "Authorization: Bearer xxxxxx",
        "Content-Type: application/json",
      ));
    $res = curl_exec($ch);
    print_r($res);
    if(curl_errno($ch))
    {
        echo 'Curl error: ' . curl_error($ch);
    }

    curl_close($ch);

I have reviewed the official documentation and I do not know what I am doing wrong, the official documentation:

Answer 1

My solution with laravel Guzzle:

/**
 * Internacional Class for SMS sending
 */
class Internacional
{
    private $api_token;
    private $rest_base_url;

    /**
     * Initialice variables
     */
    public function __construct($api_token)
    {
        $this->api_token = $api_token;
        $this->rest_base_url = config('sms.sms_internacional_route');
    }

    /**
     * Send the international SMS
     */
    public function enviar_sms($to, $message)
    {
        $now = new DateTime();
        $now = $now->format(DateTime::ISO8601);

        $full_phone = str_ireplace("+", "", $to);
        $numbers = [$full_phone];

        $promo_txt = " enviado desde Bachecubano.com";
        if (strlen($message) < 120)
            $message = $message . $promo_txt;

        $data = array(
            'from' => config('sms.international_from_number'),
            'to' => $numbers,
            'body' => $this->utf8_superencode($message),
            'delivery_report' => 'full',
            'send_at' => $now,
        );

        $headers = [
            'Authorization' => 'Bearer ' . $this->api_token,
            'Content-Type' => 'application/json',
            'Accept'        => 'application/json',
        ];
        $client = new \GuzzleHttp\Client(['headers' => $headers]);

        $response = $client->request('POST', config('sms.sms_internacional_route'), ['body' => json_encode($data)]);

        $response = $response->getBody()->getContents();

        return $response;
    }

    //Super encode this
    private function utf8_superencode($text)
    {
        return utf8_encode($text);
    }
}

Solution:

<?
$data=array('from' => 'Oso', 'to' => array('57xx'), 'body' => 'Hola este es un mensaje de prueba' );
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://sms.api.sinch.com/xms/v1/xxxx/batches");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,  json_encode($data));
curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Authorization: Bearer xxxxx",
    "Content-Type: application/json",
  ));
$res = curl_exec($ch);
print_r($res);
//var_dump(curl_getinfo($ch));
if(curl_errno($ch))
{
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);
?>

-Add an additional array () in "to" -converted Json with the json_encode function -Posdata: The "xxx" were the key and the account number

You will need to ask your SMS provider if you will use the username and password associated to your sms account along with the api.

Try this code below

<?php

//Assuming you have your sms username and password from your SMS Providers
$yoursms_username='xxxxxx';
$yoursms_password='xxxxx';


$data = array(
        //'username' => $yoursms_username,
        //'password' => $yoursms_password,
        'from'  => '506712xxxx',
        'to'  => '50671xxxx',
        'body'  => 'Hello Brother whats up.');




  // Send the POST request with cURL
$ch = curl_init('https://sms.api.sinch.com/xms/v1/xxxxx/batches');
curl_setopt($ch, CURLOPT_POST, true);

$header[ ] = "Accept: text/xml,application/xml,application/xhtml+xml,";
$header[ ] = "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";
$header[ ] = "Cache-Control: max-age=0";
    $header[ ] = "Connection: keep-alive";
    $header[ ] = "Keep-Alive: 300";
    $header[ ] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";
    $header[ ] = "Accept-Language: en-us,en;q=0.5";
    $header[ ] = "Pragma: "; // browsers keep this blank.



// also tried $header[] = "Accept: text/html";
curl_setopt ($ch,    CURLOPT_HTTPHEADER, $header);
//curl_easy_setopt(curl, CURLOPT_USERAGENT, "Mozilla/4.0");


curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result = curl_exec($ch); //This is the result from Textlocal
curl_close($ch);


if($result === false) {
echo '<font color=red>Message sending failed...</font>';

}

 else {
echo '<font color=green>SMS  Message successfully Sent</font>';
}

print($result);


?>

You claim you are POSTing JSON:

"Content-Type: application/json",

But this is how you generate the data you POST:

http_build_query($data)

And the documentation for that says:

Generate URL-encoded query string

You need to send actual JSON. Use json_encode.
