ABN Amro Bank has launched the first version of its Developer Portal, with a series of commercial application programming interfaces (APIs). The bank said it is working more closely with external developers which will help it accelerate innovation and improve its services. The bank also said it will work with creative external developers and business owners to explore the future of banking. The Developer Portal provides everything that external developers need to use the bank’s APIs effectively and productively. To start, the site will provide a number of APIs for commercial clients and basic functionalities. It also offers the use of building blocks for sending Tikkie (the bank’s payment app) payment requests and sending bulk payment orders.
