Payment Links & Checkout

This module enables Partners to accept cryptocurrency payments that are automatically converted into Euro (EUR). You can generate a ready-to-use payment interface for customers without building a custom crypto-handling backend.

Use Cases and Implementation Variants#

Choose the integration type that best fits your business flow:

1. Payment Link (Invoicing and Manual Requests)#

Best for sending payment requests directly to clients (e.g., via email, SMS, or chat) or for B2B settlements.
Usage: You generate a link and send it to the payer manually.
Configuration: Uses the standard Fintegence configuration (Standard Profile).
Scenario: A freelance client needs to pay an invoice, or you are settling a specific deal manually.

2. Hosted Checkout (App and Website Integration)#

Designed for seamless integration into your app or e-commerce flow. This is a white-label solution where the payment screen feels like part of your platform.
Usage: Your app redirects the user automatically during a purchase flow.
Configuration: Uses a Partner-specific configuration (White-label).
Scenario: A user tops up their wallet in your app or buys a product in your online store.
Key Features:
Full Branding: Displays your logo and colors.
Custom Rules: Applies your specific settings for link expiry and underpayment handling.

Core Endpoints#

Create Payment Link
Generate a shareable link for manual distribution (Standard Profile).
Create Hosted Checkout
Generate a white-label checkout session for app integration.
Get Payment Link Details
Retrieve real-time status, blockchain transactions, and payer information.

Typical Workflow#

1.
Generate: Call the appropriate endpoint for your use case: Create Payment Link for invoices or Create Hosted Checkout for app flows.
2.
Direct the User:
Payment Links: Share the returned url with your client via your preferred communication channel.
Hosted Checkout: Automatically redirect the user browser/app to the returned url.
3.
Customer Action: The customer selects a payment method (Manual Transfer, MetaMask, or WalletConnect) and sends funds.
4.
Monitor:
Webhooks: Use Payment Link Webhook for instant notifications when funds are detected on-chain.
Polling: Use Get Payment Link Details to track status and inspect detected transfers in transactions.

Key Features#

Automated Conversion to EUR#

Once payment is detected and confirmed, the cryptocurrency is automatically converted to Euro (EUR) and settled to your balance.

Underpayment Handling#

If a user sends less than the required amount, the flow enters an Awaiting Completion state. The user can pay the missing balance within the configured underpayment window to finalize the order.

Multi-Transaction Support#

A single payment link can track multiple blockchain transfers (e.g., initial payment and top-up). All detected attempts are listed in transactions, which simplifies reconciliation.
