Build with LOAN4BANK.

The LOAN4BANK Developer Portal is India's most complete financial-services API workbench for fintech engineers, product managers, DSA channel partners, banks and NBFCs building customer-facing lending, KYC and payments experiences. It bundles every asset an integration team needs — 10 production APIs across origination, servicing and payments, official SDKs in six languages, live sandbox keys, a browser-based playground, HMAC-signed webhooks, a fine-grained key management console, per-endpoint usage analytics, versioned release notes, an interactive error-code encyclopedia and a status page — behind a single sign-on developer account.

You do not need a legal review, a partnership call or an NDA to get started. Grab a sandbox key in one click, call the EMI Calculator or Financial Health Score endpoint from the browser, and ship a working prototype the same afternoon. When you're ready to route real customer traffic, upgrade to a Starter, Growth or Enterprise plan from the marketplace and the platform automatically issues a live key that hits real partner banks, KYC providers and payment rails — no code changes required, only the key prefix swaps from `l4b_sandbox_` to `l4b_live_`.

Every endpoint on the platform is regulated-grade: PCI-DSS scope-minimised, SOC 2 Type II audited, ISO 27001 certified, RBI-compliant for loan intermediation, and hosted on Indian AWS regions with data residency guarantees. That means the code you write against the LOAN4BANK sandbox is the same code you deploy into production — no security shortcuts, no last-minute retrofits before your compliance review.

New to the platform? Start with the 5-minute Quick Start, then bookmark the API Reference and Errors pages. Already integrating? Wire up webhooks so your systems learn about lifecycle events in real time, install the SDK for your language of choice, and subscribe to the changelog to hear about new endpoints as they ship.
