GCash (operated by Mynt / G-Xchange, Inc.) is the Philippines' largest mobile wallet and e-money platform, offering payments, transfers, QR checkout, bills payment, savings, lending and insurance to tens of millions of users. For developers and businesses it exposes a partner-gated API surface: the GCash API Portal (discover and subscribe to API products such as In-Store QR, Webpay, GLife and Funds Disbursement) and the GCash Mini Program Open API, which lets merchants build in-app mini programs with cashier payments, refunds and user authorization. API requests are secured with per-request RSA256/ECC224 signatures plus an OAuth2 authorization-code user flow, with idempotent payment operations and asynchronous webhook notifications. This profile was seeded as a portfolio lead and enriched from GCash's public developer documentation.
