PHP Yandex.Money API SDK

Requirements

PHP 5.3 or above, _(*2)

Getting started

Installation

Add "yandex-money/yandex-money-sdk-php": "3.0.*" to composer.json of your application. Or clone repo to your project.

If you are using composer - simply use require_once 'vendor/autoload.php'; otherwise paste following code, _(*3)

// For payments from the Yandex.Money wallet
require_once '/path/to/cloned/repo/lib/api.php';

// For payments from bank cards without authorization
require_once '/path/to/cloned/repo/lib/external_payment.php';

Payments from the Yandex.Money wallet

Using Yandex.Money API requires following steps, _(*4)

Obtain token URL and redirect user's browser to Yandex.Money service. Note: client_id, redirect_uri, client_secret are constants that you get, when register app in Yandex.Money API., _(*5)
```
use \YandexMoney\API;

$auth_url = API::buildObtainTokenUrl($client_id, $redirect_uri, $scope);
```
After that, user fills Yandex.Money HTML form and user is redirected back to REDIRECT_URI?code=CODE., _(*6)

You should immediately exchange CODE with ACCESS_TOKEN., _(*7)

$access_token_response = API::getAccessToken($client_id, $code, $redirect_uri, $client_secret=NULL);
if(property_exists($access_token_response, "error")) {
    // process error
}
$access_token = $access_token_response->access_token;

Now you can use Yandex.Money API., _(*8)

$api = new API($access_token);

// get account info
$acount_info = $api->accountInfo();

// check status 

// get operation history with last 3 records
$operation_history = $api->operationHistory(array("records"=>3));

// check status 

// make request payment
$request_payment = $api->requestPayment(array(
    "pattern_id" => "p2p",
    "to" => $money_wallet,
    "amount_due" => $amount_due,
    "comment" => $comment,
    "message" => $message,
    "label" => $label,
));

// check status 

// call process payment to finish payment
$process_payment = $api->processPayment(array(
    "request_id" => $request_payment->request_id,
));

Payments from bank cards without authorization

Fetch instantce-id(ussually only once for every client. You can store result in DB)., _(*9)

use \YandexMoney\ExternalPayment;

$response = ExternalPayment::getInstanceId($client_id);
if($response->status == "success") {
    $instance_id = $response->instance_id;
}
else {
    // throw exception with $response->error message
}

Make request payment, _(*10)

// make instance
$external_payment = ExternalPayment($instance_id);

$payment_options = array(
    // pattern_id, etc..
);
$response = $external_payment->request($payment_options);
if($response->status == "success") {
    $request_id = $response->request_id;
}
else {
    // throw exception with $response->message
}

Process the request with process-payment., _(*11)

$process_options = array(
    "request_id" => $request_id
    // other params..
);
$result = $external_payment->process($process_options);
// process $result according to docs

Side notes

Library throws exceptions in case of
- response status isn't equal 2**
- I/O error(see requests)
If you register app and fill CLIENT_SECRET entry then you should provide $client_secret explicitly where $client_secret=NULL
You should wrap all passed boolean values in quotes(because php converts them to numbers otherwise). For example:

API($access_token).requestPayment(array(
    test_payment => "true",
    // other params
));
