Payment Links for AFT Programs: How Money Transfer and Fintech Businesses Collect Payments

Payment links have become a standard tool for online commerce. But most payment link products are built for e-commerce checkout and invoicing. For businesses running Account Funding Transaction (AFT) programs—money transfers, wallet funding, prepaid card loads, and mobile top-ups—standard payment links fall short.

This guide explains how payment links built specifically for AFT programs work, why they are different from generic payment links, and how they solve the unique challenges of collecting funds for money movement.

What Is a Payment Link?

A payment link is a URL that directs a customer to a secure, hosted payment page where they can enter their card details and complete a transaction. No app download required, no account creation needed—the customer simply clicks and pays.

The typical payment link flow looks like this:

1. A business generates a payment link (manually or via API)
2. The link is sent to the customer via email, SMS, or messaging app
3. The customer opens the link on their phone or computer
4. They enter their card details on a secure hosted page
5. The payment is processed and both parties are notified

For e-commerce, this is straightforward: a customer pays for a product, the merchant receives the funds. But for AFT programs, the payment is just the beginning of a larger fund movement chain.

What Are Account Funding Transactions (AFTs)?

An Account Funding Transaction (AFT) is a card transaction where money is pulled from a debit or credit card to fund another account. Unlike a standard purchase where you buy goods or services, an AFT moves money from a card into a wallet, prepaid card, money transfer, or other financial account.

Common AFT use cases include:

• Money transfers – Funding an international remittance or domestic P2P transfer
• Digital wallet loading – Adding funds to a mobile wallet or e-wallet
• Prepaid card loading – Reloading a prepaid Visa or Mastercard
• Mobile top-ups – Purchasing airtime or data for a mobile phone
• Bill payments – Paying utility bills, insurance premiums, or loan installments

Visa and Mastercard classify AFTs differently from standard purchases. They require specific Merchant Category Codes (MCCs)—such as 4829 for money transfers and 6540 for prepaid card programs—and mandate additional data fields including sender and recipient information.

Why Standard Payment Links Don't Work for AFT Programs

Most payment link solutions on the market were designed for selling products and services. When you try to use them for account funding, several problems emerge:

They lack AFT-specific transaction coding

Visa and Mastercard require AFTs to be processed with specific MCC codes and sender/recipient data fields. Generic payment links process transactions as standard purchases, which can trigger compliance issues, declined transactions, and penalties from card networks.

They don't trigger downstream fund movement

When someone pays through a standard payment link, the transaction is complete—the merchant has received payment. When someone pays through an AFT payment link, the real work begins. The payment must trigger an OCT payout to a recipient, a wallet credit, a prepaid card load, or an airtime top-up. Generic payment links have no concept of this downstream chain.

They are optimized for email and web, not SMS and WhatsApp

Money transfer senders, mobile top-up buyers, and wallet users in emerging markets are often mobile-first. WhatsApp has a 98% message open rate compared to roughly 20% for email. Generic payment links are built around email delivery and web checkout flows, missing the channels where AFT customers actually live.

They are dashboard-first, not API-first

AFT programs need to generate thousands of payment links programmatically—one for each money transfer, top-up request, or wallet funding event. Manual dashboard creation does not scale. API-first link generation, where your platform creates links automatically within existing workflows, is essential.

How Payment Links Built for AFT Programs Work

A purpose-built AFT payment link follows a five-step flow that connects fund collection to fund movement:

Who Uses AFT Payment Links?

Money Transfer Operators (MTOs)

A sender receives an SMS or WhatsApp link, pays with their debit or credit card, and the funds are transferred to the recipient via OCT or local payout rails. The sender does not need to visit a branch, download an app, or set up a bank transfer. For MTOs expanding beyond cash-only agent networks, payment links open a digital collection channel that reaches customers wherever they are.

Mobile Top-Up and Airtime Services

A customer receives a link to load airtime for themselves or someone else. Their card is debited via AFT, and the airtime is loaded instantly via API to the mobile carrier. This is particularly powerful for cross-border top-ups, where a family member in the US can load airtime for a relative in another country with a single tap.

Prepaid Card Programs

Cardholders receive a link to reload their prepaid Visa or Mastercard. The AFT debits their bank card, and the prepaid card balance is credited in real time. No need to visit a store, call a phone number, or log into a website.

Digital Wallet Platforms

Users receive a link to fund their wallet balance. They pay with a card via the hosted page, and their wallet balance is updated instantly via webhook. This is especially useful for onboarding new users who have not yet linked a card to their wallet—the payment link serves as a frictionless first-time funding experience.

Bill Payment Platforms

A utility company or bill payment aggregator sends a payment link via SMS. The customer taps, pays, and the bill is posted in real time. No late fees, no checks in the mail, no app downloads.
