Chat API PHP SDK for messengers API

Getting started

Download SDK and unpack the archive. Connect SDK to your project.

The REST API allows you to receive and send messages through your messengers account.

Parameters in GET queries pass query string. Parameters in POST requests — through the JSON-encoded request body. The authorization token is always passed to query string (?token=xxxxxx).

The messengers API is based on the messengers WEB protocol and excludes the ban both when using libraries from mgp25 and the like. Despite this, your account can be banned by anti-spam system messengers after several clicking the "block" button.

Preparatory work

At the very beginning, we need to connect messengers with our script, so as we write the code, we check its operation. To do this, go to your personal account and get a QR code there. Next, open messengers on your smartphone, go to Settings -> messengers Web -> Scan a QR code.

Now we need to indicate a WebHook URL so the server can run the scrip when new messages arrive. Indicate a direct link to your script, e.g. You can’t indicate server IP only, but you can indicate the port.

Development of messengers Chat Bot. Full manual

We've written the most comprehensive guide on how to create a simple PHP bot using the messengers API

The first steps for beginners

The generated code has dependencies over external libraries like UniRest. These dependencies are defined in the composer.json file that comes with the SDK. To resolve these dependencies, we use the Composer package manager which requires PHP greater than 5.3.2 installed in your system. Visit to download the installer file for Composer and run it in your system. Open command prompt and type composer --version. This should display the current version of the Composer installed if the installation was successful.

  • Using command line, navigate to the directory containing the generated files (including composer.json) for the SDK.
  • Run the command composer install. This should install all the required dependencies and create the vendor directory in your project directory.

Building SDK - Step 1

[For Windows Users Only] Configuring CURL Certificate Path in php.ini

CURL used to include a list of accepted CAs, but no longer bundles ANY CA certs. So by default it will reject all SSL certificates as unverifiable. You will have to get your CA's cert and point curl at it. The steps are as follows:

  1. Download the certificate bundle (.pem file) from on to your system.
  2. Add curl.cainfo = "PATHTO/cacert.pem" to your php.ini file located in your php installation. “PATHTO” must be an absolute path containing the .pem file.
[curl]; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo = PATH_TO/cacert.pem

How to Use

The following section explains how to use the messengersAPI library in a new project.

1. Open Project in an IDE

Open an IDE for PHP like PhpStorm. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

Open project in PHPStorm - Step 1

Click on Open in PhpStorm to browse to your generated SDK directory and then click OK.

Open project in PHPStorm - Step 2

2. Add a new Test Project

Create a new directory by right clicking on the solution name as shown below:

Add a new project in PHPStorm - Step 1

Name the directory as "test"

Add a new project in PHPStorm - Step 2

Add a PHP file to this project

Add a new project in PHPStorm - Step 3

Name it "testSDK"

Add a new project in PHPStorm - Step 4

Depending on your project setup, you might need to include composer's autoloader in your PHP code to enable auto loading of classes.

require_once "../vendor/autoload.php";

It is important that the path inside require_once correctly points to the file autoload.php inside the vendor directory created during dependency installations.

Add a new project in PHPStorm - Step 4

After this you can add code to initialize the client library and acquire the instance of a Controller class. Sample code to initialize the client library and using controller methods is given in the subsequent sections.

3. Run the Test Project

To run your project you must set the Interpreter for your project. Interpreter is the PHP engine installed on your computer.

Open Settings from File menu.

Run Test Project - Step 1

Select PHP from within Languages & Frameworks

Run Test Project - Step 2

Browse for Interpreters near the Interpreter option and choose your interpreter.

Run Test Project - Step 3

Once the interpreter is selected, click OK

Run Test Project - Step 4

To run your project, right click on your PHP file inside your Test project and click on Run

Run Test Project - Step 5

How to Test

Unit tests in this SDK can be run using PHPUnit.

  1. First install the dependencies using composer including the require-dev dependencies.
  2. Run vendor\bin\phpunit --verbose from commandline to execute tests. If you have installed PHPUnit globally, run tests using phpunit --verbose instead.

You can change the PHPUnit test configuration in the phpunit.xml file.
