Payments from the Yandex.Money wallet

Using Yandex.Money API requires following steps

1. 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.

   var yandexMoney = require("yandex-money-sdk");
   // scope is array(e.g. scope = ['account-info', 'operation-history'])
   url = yandexMoney.Wallet.buildObtainTokenUrl(clientId, redirectURI, scope);
   // redirect user to url

2. After that, user fills Yandex.Money HTML form and user is redirected back to REDIRECT_URI?code=CODE.

3. You should immediately exchange CODE with ACCESS_TOKEN.

   function tokenComplete(err, data) {
       if(err) {
           // process error
       }
       var access_token = data.access_token;
       // save it to DB, config, etc..
   }
   yandexMoney.Wallet.getAccessToken(clientId, code, redirectURI, clientSecret,
       tokenComplete);

4. Now you can use Yandex.Money API.

   var api = yandexMoney.Wallet(access_token);
   
   // get account info
   api.accountInfo(function infoComplete(err, data) {
       if(err) {
           // process error
       }
       // process data
       var balance = data.balance;
       var user_account = data.account;
       // etc..
   });
   
   // fetch last 3 records of operation history
   api.operationHistory(function operationHisComplete(err, data) {
       if(err) {
           // process error
       }
       // process data
       var opertaions = data.operations;
       var first_title = operations[0].title;
       // etc..
   });
   
   //make request payment and process it
   var options = {
       "pattern_id": "p2p",
       "to": "410011161616877",
       "amount_due": "0.02",
       "comment": "test payment comment from yandex-money-nodejs",
       "message": "test payment message from yandex-money-nodejs",
       "label": "testPayment",
       "test_payment": true,
       "test_result": "success"
   };
   api.requestPayment(options, function requestComplete(err, data) {
       if(err) {
           // process error
       }
       if(data.status !== "success") {
           // process failure
       }
       var request_id = data.request_id;
   
       api.processPayment({
           "request_id": request_id
           }, processComplete);
   });
   
   function processComplete(err, data) {
       if(err) {
           // process error
       }
       // process status
   }

Payments from bank cards without authorization

1. Fetch instantce-id(ussually only once for every client. You can store result in DB).

   yandexMoney.ExternalPayment.getInstanceId(clientId,
           function getInstanceComplete(err, data) {
       if(err) {
           // process error
       }
       var instanceId = data.instance_id;
       // save it to DB
      
   });

2. Make request payment

   var external_payment = yandexMoney.ExternalPayment(instanceId)
   
   var options = {
       // pattern_id, etc..
   };
   
   external_payment.request(options, function requestComplete(err, data) {
       if(err) {
           // process error
       }
       var requestId = data.request_id;
   });

3. Process the request with process-payment.

   var options = {
       "ext_auth_success_uri": 'http://example.com/success',
       "ext_auth_fail_uri": 'http://example.com/fail',
       "instance_id": instanceId,
       "request_id": requestId
   };
   
   external_payment.process(options, function (err, data) {
       if(err) {
           // process error
       }
       // process data
   });

Side notes

1. Each API function recieves a callback in args err, data and response. Where err is equal to null when status of response is 2**, data is JSONed response and response is a full server response(you can check response.statusCode for example).

Running tests

1. Clone this repo, install deps and devDeps.
2. Create test/constants.js using test/constants.js.sample as a template.
3. Run npm run test and check the output.
