Sunbit
Sunbit is a Los Angeles based financial technology company that builds point-of-sale buy now, pay-over-time financing for everyday needs — auto service and dealerships, dental, eyewear, veterinary, med spa, home services, and general retail. Merchants and SaaS platforms integrate Sunbit through a partner API and a hosted JavaScript SDK covering four products: Pre-Qualification (send a customer a no-hard-credit-check qualification link), Sunbit Estimate (an "As Low As" monthly payment shown on a price, estimate or invoice), Checkout (Sunbit added as a payment method via a tokenized server-to-server flow and a modal), and Text to Pay-Over-Time (an SMS payment link). The platform also exposes merchant onboarding, transaction lookup, void and partial refund, reporting, and HMAC-SHA256 signed webhooks. Loans are originated through regulated bank partners.
Sunbit publishes 2 APIs on the APIs.io network. Tagged areas include buy-now-pay-later, point-of-sale-financing, consumer-lending, payments, and fintech.
The Sunbit catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Sunbit’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, pricing, and 23 more developer resources.
