Fundiin Platform Overview
Fundiin Financial Platform has two main integration surfaces:
| Surface | Audience | Purpose |
|---|---|---|
| Merchant BNPL | Merchants, commerce platforms, checkout teams | Add Fundiin BNPL to checkout, refund, status, tokenization, and on-page messaging flows. |
| Lender Integration | Lenders, loan systems, repayment teams | Sync loan lifecycle, installment schedule, payment receipt, and repayment allocation data with Fundiin. |
Both surfaces use the same platform primitives: environments, credentials, HMAC signing, idempotency, webhooks, sandbox testing, and go-live review.
