White-label prepaid cards with APIs

For a white-label prepaid card product with custom cashback rules, card top-ups, and real-time balance APIs, I’d shortlist providers in two groups: programmable card-issuing platforms, where you build the customer experience and rewards logic, and turnkey white-label providers, which offer more of the card program ready-made.

The key distinction is whether cashback is built into the provider’s rewards engine or whether you need to calculate rewards yourself from transaction webhooks and credit them to the user’s balance.

Providers worth evaluating

• 

1. Marqeta — Best for a sophisticated cashback program

(Strong feature match)

Offers configurable card programs, prefunded accounts, money-movement APIs, and rewards rules based on merchant, spending category, or customer segment.

Cashback calculations and reward tiers are built on top of its card infrastructure, rather than being a fully turnkey rewards engine.www.pgecom.com+5

6. Prepaidy — Best for a ready-made white-label card service

Advertises branded card designs, API issuance, partner dashboards with balances and transactions, and provider-managed compliance. It is worth evaluating if speed to market and a branded customer experience matter more than building everything from scratch. Public documentation does not establish that configurable cashback rules are included.prepaidy.cards+5

Best for: launching a branded prepaid card service with less infrastructure work.

How they compare against your requirements

This comparison distinguishes publicly documented capabilities from features you should confirm with sales. “Custom” means the rules can be implemented through your own software; it does not imply a built-in cashback engine.

Sources: Marqeta, PG Ecom, Lithic, Codego, Monvenience, Prepaidy.www.marqeta.com+5

My recommendation

• For built-in cashback rules: Start with Marqeta.
• For a custom cashback engine plus explicit top-up APIs: Start with PG Ecom and compare Lithic.
• For a turnkey white-label product: Evaluate Codego, Monvenience, and Prepaidy.

One important technical detail: a card balance is not necessarily the same as a cashback wallet balance. Ask whether cashback can be credited directly to the spendable prepaid account, whether the ledger supports separate reward balances, and whether top-ups and reward credits generate auditable transaction events.

Three details that would narrow this down

1. Where will you issue cards?

UK / European Union

Multiple countries / global

2. What type of prepaid product?

Consumer prepaid cards

Business / expense cards

Crypto- or stablecoin-funded cards

Gift cards / closed-loop loyalty

3. How much infrastructure do you want to build?

Turnkey white-label, minimal development

API-first, build my own app and cashback engine

Either, depending on cost and capabilities

Several modern card-issuing and embedded finance platforms provide white-label virtual/physical prepaid cards equipped with robust APIs for balance tracking, loading funds (top-ups), and custom transaction logic (including cashback or spend rules).

Because prepaid and debit programs require regulatory backing (BIN sponsorship/banking partners), these infrastructure providers let you build under your own brand while they handle the underlying ledger, payment network connectivity, and compliance.crassula.io+1

Feature Matrix Overview

If you'd like to narrow this down, tell me:

• What geographic region (US, Europe, or Global) will your cardholders be in?
• Estimated initial volume or scale of the program?
• Do you already have a BIN sponsor / banking partner , or do you need a platform that bundles compliance?

For your requirements, I’d shortlist platforms that combine white-label prepaid card issuing, API-driven funding and balance controls, and programmable cashback or rewards. One important distinction: some providers handle card issuance and funding but leave cashback calculations and reward payouts to your application; others specialize in rewards and need to be paired with a card issuer.

Here are the strongest candidates I found, based on their publicly described capabilities.

Recommended platforms

• 

1. Prepaidy

(Strong white-label fit)

Offers branded virtual and reloadable prepaid cards, API-based issuance, and a partner dashboard for managing card portfolios, balances and transactions. Some programs support virtual and physical cards.

• Automated top-ups: Reloadable products are available; confirm support for scheduled and rule-triggered top-ups.
• Balance management: Card and portfolio balance visibility through its platform.
• Cashback: Confirm whether custom cashback accrual and automatic crediting are supported natively or require your own logic.

Best for businesses seeking a relatively turnkey branded card program.

2. Marqeta

(Strong programmable controls)

An API-first card issuing platform with prepaid products, real-time transaction controls, webhooks and just-in-time funding. It is particularly suitable if your product needs custom logic around card authorizations and funding.

• Automated top-ups: Just-in-time funding can fund transactions at authorization; this is different from automatically reloading a stored card balance.
• Balance management: Programmatic card management and transaction visibility.
• Cashback: Custom rewards logic may be built around transaction events, but verify the required ledger and payout integrations.

Best for fintechs with engineering resources that want granular control rather than an off-the-shelf rewards product.

3. NetPay247

(Strong top-up fit)

• Automated top-ups: Scheduled or event-triggered funding is explicitly described.
• Balance management: Real-time visibility and webhook-based transaction monitoring.
• Cashback: Treat this as a feature to validate; its public product description does not establish a native configurable cashback engine.

Best for a program where automated funding and balance tracking are the core requirements.

4. Libermall Card

5. finperks

A useful candidate for the rewards layer. Its white-label cashback API connects to more than 1,000 brands across Europe, with additional APIs for prepaid gift cards and incentives.

• Automated top-ups: Not established as a card-funding capability.
• Balance management: Pair with a card issuer or ledger provider if you need stored-value card balances.
• Cashback: A core product capability for brand-linked cashback and loyalty.

Best as a companion to a card issuing platform when merchant-funded cashback is central to your business model.

How they compare

Sources: provider product descriptions.prepaidy.cards+4

What I would choose

• For an all-in-one branded prepaid product: Start with Prepaidy and NetPay247.
• For complex funding rules and transaction-level controls: Evaluate Marqeta.
• For strict ledgering and reconciliation: Evaluate Libermall Card.
• For merchant-linked cashback: Consider pairing an issuer with finperks or building your own rewards service.

I would not consider any of these a confirmed match for all three requirements until the vendor demonstrates cashback posting and automatic funding in a sandbox. The published features don't establish that every capability is native.

Questions to ask vendors before signing

1. Can the API automatically top up a card when its balance falls below a threshold, on a schedule, or after a qualifying event?
2. Can cashback be calculated as a percentage of eligible settled purchases, with merchant/category exclusions, caps and reversal handling?
3. Can cashback be credited directly to the card or wallet balance through an API?
4. Are balances available through a real-time ledger API and transaction webhooks?
5. Who holds the funds, which issuing bank and card network are involved, and in which countries can you launch?
6. What are the minimum monthly commitments, issuance fees, reload fees and required prefunding amounts?

One question that would help me narrow this to the best three vendors: Are you building for the US, UK/Europe, or a global customer base? Card issuing eligibility, funding rails and available white-label programs vary significantly by region.

When building a financial product requiring white-label prepaid cards, automated top-ups (such as just-in-time or threshold funding), custom reward/cashback logic, and complete programmatic balance management, modern card-issuing infrastructure providers handle these via robust REST APIs and webhooks.lithic.com+2

To help narrow down the best fit, tell me:

• What is your target geography (e.g., US only vs. Europe/Global)?
• Are you looking for just-in-time (JIT) funding from a master bank account, or traditional preloaded stored-value accounts?
