Demo Token: 1234567890123456789
Request Methods: POST (recommended) & GET
Parameters: to, message, token
You can use this API in GET and POST method.
First Login Your SMS Portal and Generate Access Token from the below link
https://sms.greenweb.com.bd/index.php?ref=gen_token.php
If you dont have any account you can use this demo token for integrating purposes: 1234567890123456789
It will not send any SMS but will return response like the real token, so for integrating our API with your software you can use it. Please replace this demo token with the real one after completing your integrating.
Request Method & Parameters:
token = Generate it from sms panelto = Recipient Numbers । Format must be +8801xxxxxxxxx or 01xxxxxxxxx (Bangladeshi Number format) message = whatever you want to send
For Example:
POST Method
If you're using GET METHOD you have to URL ENCODE message text. For URL Encoding you can use rawurlencode() in php । if its javascript you can use encodeURI()
JSON Data Format:
By Default Our API Retun Line by Line seperated html response । You can take each line in array and match Ok: for success and for the error you can match Error: word । For example:
Ok: SMS Sent Successfully To +8801xxxxxxxxx
Error: +8801xxxxxxxxx Invalid Number !
You got the above response now take it in an array
$smsresultarray = preg_split('/\r\n|\r|\n/', $smsresult);
now process the array
foreach($smsresultarray as $result) {
$status = mb_substr($result, 0, 2);
if ($status == 'Ok') {
//sms successfully sent do whatever you want
echo $result;
} else {
//failed to sent do whatever you want
echo $result;
}
}
You can get JSON Response by input &json at the end of the url like this http://api.greenweb.com.bd/api.php?json
For example :
<?php
$to = "017xxxxxxx,+88016xxxxxxx";
$token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$message = "Test SMS using API";
//Put &json in here ->
$url = "http://api.greenweb.com.bd/api.php?json";
$data= array(
'to'=>"$to",
'message'=>"$message",
'token'=>"$token",
'json'=>"1",
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$smsresult = curl_exec($ch);
//Result
echo $smsresult;
//Error Display
echo curl_error($ch);
?>
Now you'll get output like this :
[
{
"to": "+8801xxxxxxx",
"message": "test sms",
"status": "SENT",
"statusmsg": "SMS Sent Successfully To +8801xxxxxxx"
},
{
"to": "+8801xxxxxxx",
"message": "test sms",
"status": "FAILED",
"statusmsg": "+8801xxxxxxx Invalid Number"
}
]
How to process it in php?
$smsresult = json_decode($smsresult);
foreach ($smsresult as $result) {
if ($result->status == "SENT") {
echo "SMS sent successfully";
echo $result->to;
echo $result->status;
echo $result->statusmsg;
} else {
echo "Failed to send";
echo $result->to;
echo $result->status;
echo $result->statusmsg;
}
}
For sending sms you need three data. 1. to (it is the receiver phone number), 2. message (it is the text you want to send) 3. token (you have to generate it from the panel, it will works as a key)
<?php
//Take Data from your database in your own way in a loop
$dblink = mysqli_connect("localhost", "dbusername", "dbpassword", "dbname");
/* If connection fails throw an error */
if (mysqli_connect_errno()) {
echo "Could not connect to database: Error: ".mysqli_connect_error();
exit();
}
$sqlquery = "SELECT number FROM table_name";
if ($result = mysqli_query($dblink, $sqlquery)) {
/* fetch associative array */
while ($row = mysqli_fetch_assoc($result)) {
$number = $row["number"];
$to = "$number,$to";
}
}
// We got all numbers in a string called $to now we will send sms
$token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$message = "Test SMS using API";
$url = "http://api.greenweb.com.bd/api.php";
$data= array(
'to'=>"$to",
'message'=>"$message",
'token'=>"$token"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$smsresult = curl_exec($ch);
//Result
echo $smsresult;
//Error Display
echo curl_error($ch);
?>

Setup:
It is recommended to instantiate one HttpClient for your application's lifetime and share it.
private static readonly HttpClient client = new HttpClient();
POST:
var values = new Dictionary
{
{ "token", "yourtokenhere" },
{ "to", "016xxxxxxxxx" },
{ "message", "test" }
};
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync("http://api.greenweb.com.bd/api.php?", content);
var responseString = await response.Content.ReadAsStringAsync();
Newer library sporting a fluent API and testing helpers. HttpClient under the hood. Portable. Available via NuGet.

POST
var responseString = await "http://api.greenweb.com.bd/api.php?"
.PostUrlEncodedAsync(new { token = "yourtokencodehere", to = "015xxxxxxx", message = "my message" })
