Pomelo (pomelo.la) is a Latin American card-issuing and embedded-finance platform. Its REST API lets fintechs and enterprises onboard users (KYC/KYB), issue physical and virtual cards, manage card accounts and balances, process and query transactions, move money with transfers and settlements, and authorize transactions in real time over a synchronous authorization webhook.
