Citi has launched a global API Developer Hub to give developers access to APIs across eight usage categories including account management, peer-to-peer payments, money transfer to institutions, Citi rewards, investment purchases and account authorisation. “The release of Citi APIs marks the evolution of Citi’s technology to open architecture, which will facilitate collaboration and partnerships with fintech companies and consumer brands to benefit customers,” Citi says. Additional categories will be added over time.
