The Best Bank Portugal Connect is a C# SDK (.NET/.NET Core) that helps (a lot!) to connect to the Open Banking API of the portuguese bank Banco Best (Best Bank). The Banco Best is the first bank to implement the PSD2 (Payment Services Directive) in Portugal.
With this SDK is possible to make Android and iOS applications using Xamarin. Not just mobile applications, since that .NET Framework and .NET Core works on a wide places, it's possible to use this SDK in these places too.
This library helps to:
- 💶 Get bank accounts balances.
- 💳 Get bank account and credit card moviments.
- 💸 Make transferences between two bank accounts.
- 💸 Make payments.
- 🛂 Authorization Flow (OAuth 2)
The main entry point for the API is to create a valid BestBankConnector object:
// Set your application details
var app = new Application(appConsumer, appSecret, Environment.Sandbox);
// Set the user Access Token (In this case this user already made the whole OAUth 2 previously)
var user = new User(accessToken);
// Setup a BestBankConnector object
var api = new BestBankConnector(user, app);
// Get for example the account balance
var balance = api.Balance(); This SDK also simplify the painful OAuth 2.0 authorization flow with the AuthorizationFlow object:
// Step 1: Gets the URL Login where the Banco Best costumer will authorize the app to access his accounts
var url = AuthorizationFlow.GetBankLoginUrl(app,@"http:\\www.httpbin.org\get");
// .... Wait the costumer back to the application ... //
// Step 2: Gets the user Access Token based on a temporary code returned after the costumer authorization
var accessToken = AuthorizationFlow.GetUserAccessToken(app, temporaryCode);You can access the official SDK documentaion here on the repository wiki. Also, if you take a look at the repository files, there is a .NET Core console app example where you could see step by step examples from the authorization flow to a balance request.
