Efí
Efí (formerly Gerencianet) is a Brazilian payment institution and digital bank that exposes well-documented public REST APIs for the Brazilian financial system - Pix (immediate and dated charges, send/receive, refunds, webhooks), Boletos and Charges (Cobranças), Carnê installment booklets, subscriptions and payment links, Pix via Open Finance, and account financial services. Pix and Open Finance APIs require OAuth2 client-credentials plus a mutual TLS (mTLS) client certificate as mandated by the Brazilian Central Bank; the Cobranças API uses OAuth2 without mTLS.
