Welcome

Embed a full invoicing and payment-collection workflow directly in your application with just a few API calls. Adfin exposes a unified REST API—protected by OAuth 2.0—for creating, activating and tracking invoices, scheduling one-off or recurring payments, and reconciling funds across cards, direct debit and open-banking channels.

Why it Matters for Your Platform

• Idempotent POST /invoices, PUT /invoices/activate and scheduler APIs make it easy to generate invoices, kick off payment collection and set up custom retry or notification workflows.
• Real-Time Eventing: Webhooks (with built-in signature verification and retry logic) notify you instantly of invoice state changes, payment confirmations or mandate updates—no polling required (though it’s supported as a fallback).
• Unified Data Model: One normalized schema abstracts away differences between payment methods and external accounting connectors (like Xero and QuickBooks), so you can sync customer, invoice and payment data two-ways without bespoke mapping or reconciliation logic.
• Built-In Compliance & Security: OAuth 2.0 + TLS encryption, PCI-DSS scope reduction via hosted payment pages, and audit-ready logs give you enterprise-grade security without heavy lifting.

The result?

A plug-and-play “money in” solution that lets your customers generate invoices, collect payments and reconcile accounts automatically—dramatically reducing your integration time, cutting costs on manual chasing, and delivering a seamless end-user experience.
