Open Bank API client implemented with Spring Boot

This is a technology demonstration of the OBP API v3.1.0 capabilities. This project provides Java bindings to sveral OBP REST API endpoints, including banks, branches, accounts and transactions. Included is also a demo webpage that puts all available bank branches in the https://apisandbox.openbankproject.com sandbox on a map.

Setup and run

The OBP Client API is using Spring Boot 2.1.x and needs JDK 10.

Sign-up at the OBP sandbox: https://apisandbox.openbankproject.com/ Note the consumer key, username and password. Then edit /src/main/resources/application.properties and paste the consumer key above as the obp.consumerKey value.

The standard command ./gradlew bootRun will start a Tomcat container running on port 8080. Open a browser and browse to http://localhost:8080

To login, use the username and password you noted above. After a successful login, a map with all available branches present in the apisandbox will be displayed.

Only a small subset of the full API capabilities are integrated in the webapp (banks, branches).

OBP Java API bindings (v3.1.0)

The OBP REST API is made available as a native Java API by the com.tesobe.obp.clientapi.*ApiClient classes. Accounts and transactions are available as many other OBP API capabilities. See the integration test suite for example usage. Caveat: currently, the supported version is v3.1.0. Also, not all of the REST API implemented.

Code organization

The code is organized between main and test directories. The tests are covering the following functionality:

  • Authentication
  • Get account details
  • Get transactions for an account
  • Tag transactions
  • Add geolocation to transaction

Dependencies

The single external dependency is on a live OBP sandbox that needs to run in order for the tested functionality to be successful. This sample project is using the version 2.2.0 of the OBP API. It shouldn't be difficult to use a different API version with the caveat that some of the entities must be adapted to match the data in the target API version.

The OBP client API is abstracted via Feign, a declarative REST client. See ObpApiClient and DirectAuthenticationClient for implementation details.

Internally, the project is also using Lombok to simplify the code and the Joda Money API for representing monetary values.

Test and build

Run all tests with: ./gradlew clean build

There is a fat jar build as well, available under build/libs that can be executed with java -jar obp-api-client.jar
