Today, the University of Michigan's "Next Billion" initiative writes about Bill and Melinda Gates Foundation research into financial inclusion and fintech; part of the research addresses payment aggregators that use APIs to connect buyers, commercial enterprises and other clearinghouses; the research claims that creating truly open APIs, which don't require complex legal agreements or technical integrations between parties, would be of great benefit to the financial ecosystem, including enhanced innovation and reduced transaction costs; a case study about Selcom, an African payment aggregator, highlights six areas suitable for near-term open API development: payment initiation (including via mobile wallets and online chatbots), check payment status, retrieving account history, easily cancelling a payment and a set of user interface foundation code that can be white-labelled by any customer-facing innovator.  Source
