Send SMS via Symfony

Are you working with Symfony? Check out the notifier component. It makes sending SMS via seven easy! You may also want to have a look at the official repository in case you wish to contribute or simply watch the project process.

Send SMS via Laravel

Are you building your application with the very popular framework Laravel? Some nice people made the work integrating our service into Laravel Notification Channels. The package greatly reduces a developers workload and just works flawless. You download and read more about it here.


public class sms {
	public static void main(String[] args) {
		String urlString = "";

		String output	= getUrlContents(urlString);

	private static String getUrlContents(String theUrl)
		StringBuilder content = new StringBuilder();

		// many of these calls can throw exceptions, so i've just
		// wrapped them all in one try/catch statement.
			// create a url object
			URL url = new URL(theUrl);

			// create a urlconnection object
			URLConnection urlConnection = url.openConnection();

			// wrap the urlconnection in a bufferedreader
			BufferedReader bufferedReader = new BufferedReader(
				new InputStreamReader(urlConnection.getInputStream())

			String line;

			// read from the urlconnection via the bufferedreader
			while ((line = bufferedReader.readLine()) != null)
				content.append(line + "n");
		catch(Exception e)
		return content.toString();

For implementation with Ruby, you can use our Gem.

require 'sms77'

# or

We provide a client for our API for better usability. It is also available via the central package distribution system NuGet.


using System;
using System.Threading.Tasks;
using Client = Sms77.Api.Client;

class Program
    static async Task Main()
        var apiKey = Environment.GetEnvironmentVariable("SMS77_API_KEY");
        var client = new Client(apiKey);
        var balance = await client.Balance();
        Console.WriteLine($"Current account balance: {balance}");

For easier usability we are providing a client for our API. You can read more about it at


package main

import (

func main() {
	var client = sms77api.New(sms77api.Options{
		ApiKey: "InsertSuperSecretSms77ApiKey!",
	var balance, err = client.Balance.Get()
	if err == nil {
		fmt.Println(fmt.Sprintf("%f", *balance))
	} else {

We deliver a client for our API for better accessibility. It is distributed as a NPM package.



// const globalThis = require('globalthis')(); // uncomment if NodeJS < NodeJS versions < 12
globalThis.fetch = require('node-fetch').default;
const Sms77Client = require('sms77-client');


<script src=""></script>

Retrieve balance

new Sms77Client("INSERT_SMS77_API_KEY")
	.then(balance => console.log(`Current balance: ${balance}`))


# If your API key is not set as environment variable named "SMS77_API_KEY":
# Application.put_env(:sms77, :api_key, "INSERT_YOUR_SMS77_API_KEY")

IO.puts Sms77.Balance.get! # prints the account balance to console

We developed a SDK in Rust for convenience reasons. You can download it via The source code is available on GitHub. Feel free to open issues or even come up with a pull request on your own.

let apiKey = "INSERT_YOUR_API_KEY".to_string();

let client = Client::new(apiKey);

let balance = Balance::new(client).get().unwrap();
println!("Current balance: {}", balance);

Use this convenient code snippet for quickly send a SMS via a Perl script.


use LWP::UserAgent;

my %form;
$form{'p'} = 'HeJyJSAvBWDn5RwNfhQGKZI6poCLk7pUXjpxctipYHWGsjoHtWNDI3d4De8gkoVe'; # Your API key
$form{'from'} = 'seven'; # Caller ID
$form{'text'} = 'Bless you!'; # Message content
$form{'to'} = '+491771783130'; # Recipient(s)

my $ua = LWP::UserAgent->new();
my $response = $ua->post('', \%form );
my $content = $response->as_string();
