Fintecture

Fintecture is a licensed and one-stop shop gateway to Open Banking.

Our APIs allow easy and secure access to bank account data and payment initiation. The account data accessible are account holder's personal information, account balances, transaction history and much more. The available payment methods depend on the banks implementation but typically are domestic transfers, SEPA credit transfer, instant SEPA credit transfer, fast payment scheme, and SWIFT international payments.

Fintecture APIs enable to connect to both Production and Sandbox environments of banks. Our Sandbox has the particularity of being connected to other banks' Sandbox. This will give you a flavour of what you can expect in production in terms of user experience and data sets.

Installation

npminstall'fintecture-client'

Usage

The SDK enables multiple use cases. Essentially, it runs down to whether you want / need to go through our bank selection module "Fintecture Connect" ( which is mandatory if you're not an Agent or a licensed TPP. )

This section is divided based on the following use cases:

• First Steps
• Use Cases
  • AIS without Connect
  • AIS with Connect
  • PIS without Connect
  • PIS with Connect

Get Started

Independantly of the use case, the first step is to create a developer account on the Fintecture Console and create an application to get your app_id, app_secret and private_key.

You are now ready to start coding. Next step is import the Fintecture Client library and instantiate the client object:

const{ FintectureClient }=require('fintecture-client');letclient=newFintectureClient({app_id: process.env.APP_ID,app_secret: process.env.APP_SECRET,private_key: process.env.APP_PRIV_KEY,env: process.env.FINTECTURE_ENV,});

Use Cases

AIS without Connect

To access the PSU's account information, you have to go through the following steps:

Scenario 1: Redirect Model

1. Select a Bank

letoptions={'filter[ais]': 'accounts','filter[country]': 'FR','filter[psu_type]': 'retail','filter[auth_model]': 'redirect','sort[full_name]': 'asc',};letproviders=awaitclient.getProviders(options);

2. Get the bank's authentication URL and redirect your PSU to his bank

letproviderAuth=awaitclient.getRedirectAuthUrl(null,providerId,redirectUri,state);windows.href.location=providerAuth.url;

3. Authenticate your app to Fintecture and get your access_token and refresh_token

lettoken=awaitclient.getAccessToken(code);

4. Request any AIS API

letaccounts=awaitclient.getAccounts(accessToken,customerId);letaccount=accounts.data[0].id;lettransactions=awaitclient.getTransactions(accessToken,customerId,account);

Note that the code and customer_id are returned as query parameters when the PSU is redirected back to your environment.

Scenario 2: Decoupled Model

1. Select a Bank

letoptions={'filter[ais]': 'accounts','filter[country]': 'FR','filter[psu_type]': 'retail','filter[auth_model]': 'decoupled','sort[full_name]': 'asc',};letproviders=awaitclient.getProviders(options);

2. Get the provider's decoupled auth polling URL

letproviderAuth=awaitclient.getDecoupledAuthUrl(null,providerId,psuId,psuIpAddress);letpollingId=providerAuth.polling_id;

3. Keep polling the provider's decoupled auth polling URL until authentication either COMPLETED or FAILED

letcustomerId=null;letcode=null;varloop=setInterval(function(){letauth=awaitclient.getDecoupledAuthStatus(null,providerId,pollingId);if(auth.status!='PENDING'){customerId=auth.customer_id;code=auth.code;clearInterval(loop);}},2000);

4. Authenticate your app to Fintecture and get your access_token and refresh_token

lettoken=awaitclient.getAccessToken(code);

5. Request any AIS API

letaccounts=awaitclient.getAccounts(accessToken,customerId);letaccount=accounts.data[0].id;lettransactions=awaitclient.getTransactions(accessToken,customerId,account);

Note that the code and customer_id are returned as query parameters when the PSU is redirected back to your environment.

AIS with Connect

To enable AIS using connect, simply redirect the PSU to the generated URL:

letconfig={redirect_uri: 'https://mysite.com/callback',state: 'thisisastate',psu_type: 'retail',country: 'fr',};letconnect=awaitclient.getAisConnect(null,config);window.href.location=connect.url;

On callback, exchange the code for an accesstoken, and use the accesstoken coupled with the customer_id to get your PSU AIS resources:

// save querystring parametersconstcode=req.query.code;constcustomerId=req.query.customer_id;// get the Fintecture access token to request the AIS APIsconsttoken=awaitclient.getAccessToken(code);constaccounts=awaitclient.getAccounts(token.access_token,customerId);

PIS without Connect

The initiate a payment on behalf of a PSU, you have to go through the following steps:

1. Select a Bank

letoptions={'filter[pis]': 'SEPA','filter[country]': 'FR','filter[psu_type]': 'retail','sort[full_name]': 'asc',};letproviders=awaitclient.getProviders(options);

2. Authenticate your app to Fintecture and get your access_token

lettoken=awaitclient.getAccessToken();

3. Initiate a payment

letpayment={data: {type: 'PIS',attributes: {amount: '1',currency: 'EUR',communication: 'Thanks Mom!',beneficiary: {name: 'Bob Smith',address: '8 road of somewhere, 80330 Lisboa',country: 'ES',iban: 'PT07BARC20325388680799',swift_bic: 'DEUTPTFF',},},},};letresponse=awaitclient.paymentInitiate(accessToken,providerId,payment,redirectUri,state);

PIS with Connect

The initiate a payment on behalf of a PSU using Fintecture Connect, just do:

letconnectConfig={amount: '125',currency: 'EUR',communication: 'Thanks mom!',customer_full_name: 'Bob Smith',customer_email: 'bob.smith@gmail.com',customer_ip: '127.0.0.1',state: 'somestate',};lettoken=awaitclient.getAccessToken();letconnect=awaitclient.getPisConnect(token.access_token,connectConfig);window.href.location=connect.url;// and at any time (ex: to validate a payment on callback)letpayment=awaitclient.getPayments(token.access_token,connect.session_id);console.log('PAYMENT STATUS:',payment.meta.status);

Description of Connect fields:

• amount: [mandatory] The amount of the payment initiation request. Min 1.00 and Max is variable based on bank's policy.
• currency: [mandatory] The currency of the payment initiation request. Currently, only EUR and GBP is supported.
• communication: [optional] A message sent to the beneficiary of the payment and visible on his bank statement. In the context of ecommerce payment collection, the order reference is inputted here.
• customer_full_name: [mandatory] the full name of the payer
• customer_email: [mandatory] the email of the payer
• customer_ip: [mandatory] the ip address of the payer
• redirect_uri: [optional] the callback URL to which the customer is redirected after authentication with his bank
• origin_uri: [optional] a URL to which the customer will be redirected if he wants to exit Fintecture Connect
• state: [mandatory] A state parameter which is sent back on callback. In the context of ecommerce, input the order ID here.
• expiry: [optional] The time in seconds which the link is valid before it expires (Default: no expiry)
• payment_methods: [optional] A list of payment methods to be added to the selector on Connect. Example: ['immediate_transfer', 'smart_transfer']. Available values can be found on docs in meta section.

Pagination

Pagination can occur on the transaction endpoint. When requesting the getTransaction() function, you will receive a $.links.next URL. In order to iterate on the pages, supply that URL in the paginationURL field within the getTransactions function:

lettransactionsPages=[];lettransactions=awaitclient.getTransactions(accessToken,customerId,accountId,headers);transactionsPages.push(transactions);while(transactions.links.next){transactions=awaitclient.getTransactions(accessToken,customerId,accountId,headers,transactions.links.next);transactionsPages.push(transactions);}
