Billplz
Billplz is a Malaysian payment-collection API built around Collections (groups) and Bills (individual payment requests), supporting FPX online banking, cards, e-wallets, and buy-now-pay-later options (PayLater, Atome) with next-business-day payouts. Requests authenticate via HTTP Basic Auth using an API secret key as the username, must run over HTTPS, and accept/return JSON; GET endpoints are rate-limited to 100 or 10 requests per 5-minute window depending on the plan. A live Origin-header probe found no Access-Control-Allow-Origin header on either GET or OPTIONS requests, so browser-side calls need a server-side proxy.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
