What Is Marqeta and How Does It Work?

Imagine you’re building a startup — maybe a rideshare app, a gig-economy platform, or a digital bank. You need to issue payment cards, manage user spending, and handle payouts — but building banking infrastructure from scratch is slow, costly, and complex.

That’s exactly the problem that Marqeta solves.

Marqeta is a modern card-issuing and payments infrastructure platform: it lets companies create virtual or physical debit, prepaid, or credit cards on demand, control spend rules dynamically, process payments, and manage funds — all via open APIs.

Today, many of the fintech, on-demand service, and banking apps you use (directly or indirectly) rely on Marqeta behind the scenes. Whether it’s paying a driver, giving a consumer a card, or enabling instant payouts — Marqeta gives businesses the tools to build customized payment experiences without dealing with legacy banking hassles.

In this guide, you’ll learn:

• What Marqeta actually is
• How Marqeta works — from card issuing to payment processing

For Businesses (Fintechs, Marketplaces, Platforms)

1. Create an Account & Set Up a Card Program

Companies integrate Marqeta using its APIs. They choose:

• Card type (debit, prepaid, credit, virtual, tokenized)
• Funding model (just-in-time funding, prefunded accounts, pooled balance)
• Spend controls and rules

This setup allows businesses to design custom card behavior for their users.

2. Issue Cards Instantly (Physical + Virtual)

Businesses can create cards in seconds through API:

• Virtual cards for online payments
• Tokenized cards for Apple/Google Pay
• Physical plastic cards mailed to users
• Single-use or multi-use cards
• Vendor-specific cards with restricted spending

This is why gig apps, banks, and SaaS platforms love Marqeta.

3. Real-Time Authorization

Every card swipe or online payment is checked by Marqeta’s Dynamic Authorization Engine, which instantly verifies:

• User identity
• Available balance
• Spending limits
• Merchant category
• Allowed regions
• Risk patterns

The business can approve/decline transactions instantly using its own rules.

4. Payouts & Funding Flows

Marqeta also powers fast payouts:

Marqeta’s Business Model Explained

Marqeta earns revenue through a combination of interchange fees, platform usage fees, and value-added payment services. Its model is powerful because it scales automatically with transaction volume — the more its clients grow, the more Marqeta earns.

1. Interchange Revenue (Primary Stream)

Every time a Marqeta-issued card is used, the merchant pays a small fee to the card network (Visa/Mastercard).
A portion of that fee — interchange — goes to Marqeta.

Because Marqeta powers high-volume businesses (fintech apps, gig platforms, digital banks), interchange adds up massively.

2. Processing & Program Fees

Marqeta charges businesses for:

• Card issuing
• Transaction processing
• Program management
• Compliance & KYC support
• BIN sponsorship through partner banks
  These fees create predictable monthly revenue.

3. Card Manufacturing & Fulfillment

For physical cards, businesses pay for:

• Card printing
• Custom branding
• Packaging
• Shipping
  Marqeta earns fees for facilitating and managing this.

4. Just-in-Time Funding Fees

One of Marqeta’s signature features is JIT Funding, where funds are authorized and pulled only when a transaction occurs.
Clients pay for:

• Real-time balance checks
• Funding API calls
• Ledger updates
  This is extremely popular with gig, fleet, and expense apps.

5. Value-Added Services

Marqeta also earns from:

• Fraud protection tools
• Dispute management
• Tokenization (Apple Pay, Google Pay)
• International payment support
• Custom network routing
• FX fees on global transactions

6. Large Enterprise Partnerships

Fintech giants, banks, and enterprise platforms bring massive long-term revenue through:

• Volume-based agreements
• White-label issuing
• Co-branded card programs

Why Marqeta’s Business Model Works

✔ High scalability — revenue grows as clients grow
✔ Sticky integrations — once a company builds on Marqeta, switching is difficult
✔ API-first approach — attracts modern businesses, SaaS tools, and fintechs
✔ Multiple revenue streams — diversified and recurring

By powering the backend for many major payment apps, Marqeta has built a foundation layer of the global fintech ecosystem.

Key Features That Make Marqeta Successful

Programmable Card Issuing (Physical + Virtual)

Marqeta’s core strength is that card issuing is fully programmable. Instead of forms and long bank timelines, businesses can:

• Create virtual cards on demand
• Order branded physical cards
• Issue single-use or multi-use cards
• Generate cards per user, per vendor, or per transaction
  All of this happens via API calls, so product teams can bake card issuing directly into their app flows.

Dynamic Spend Controls in Real Time

Every transaction can be checked against business-defined rules before approval. You can control:

• Where the card can be used (merchant category, country)
• When it can be used (time-based rules)
• How much can be spent (limits, per-transaction caps)
• What it can be used for (e.g., “fuel-only”, “online-only”)
  This is powerful for fleet cards, gig payouts, expense tools, and virtual card platforms.

Just-in-Time (JIT) Funding

With JIT funding, the card doesn’t hold a big static balance. Instead, when a user swipes the card, Marqeta:

1. Checks the request
2. Calls your app’s logic or ledger
3. Funds just enough for that transaction
4. Approves or declines in real time

That means better risk control, lower idle balance, and tighter cash management, especially for gig and B2B platforms.

Tokenization & Digital Wallet Support

Marqeta supports tokenization, letting cards work in:

• Apple Pay
• Google Pay
• Other digital wallets

This is crucial for mobile-first apps, subscription platforms, and contactless payments.

Global Network Connections

Marqeta integrates with major card networks and issuing banks, so clients get:

• Worldwide card acceptance (where networks are supported)
• Multi-region issuing capabilities (where available)
• Support for local regulations and compliance via partner banks

This helps fintechs go from local to global without rebuilding infrastructure.

Powerful Developer Experience (DX)

Marqeta is loved by engineering teams because it offers:

• Clean RESTful APIs
• Sandbox environments
• Detailed documentation
• Webhooks for transaction events
• Test card numbers and mock scenarios

This developer-first approach is one of the main reasons startups and large platforms choose Marqeta over legacy providers.

Advanced Data & Authorization Engine

Behind every swipe, Marqeta’s engine can:

• Enrich data with merchant info, category, region
• Apply risk checks and rules instantly
• Send real-time webhooks to client systems
• Support advanced logic like split payments or routing

This allows clients to build custom payment experiences (e.g., split fares, marketplace payouts, controlled employee cards).

Fraud, Risk & Compliance Tools

Marqeta also supports:

• Transaction monitoring
• Velocity checks
• Geo and MCC restrictions
• Dispute and chargeback workflows
  These features make it easier for clients to maintain regulatory and risk standards without building everything from scratch.

What Truly Sets Marqeta Apart

Marqeta’s biggest differentiation is that it turned card issuing into a programmable API layer. Instead of thinking “card + bank,” businesses think “card as code” — and that mindset is exactly what modern fintech, gig platforms, and embedded finance products need.
