USDC Payment APIs

USDC Payment Integration Services

We integrate USDC payment APIs into checkout, invoicing, and treasury workflows. From payment-session creation and wallet funding logic to signed webhooks, reconciliation, and merchant settlement operations, we build the software layer teams need to run USDC as a serious payment rail.

What We Build

USDC Checkout APIs

Add USDC payment intents to your checkout flow with amount quoting, payment-session creation, wallet instructions, and confirmation handling that fits your existing product UX.

USDC Invoicing & Payment Links

Create payment links and invoice flows with fixed amounts, order references, and expiry logic for B2B collections, service billing, and merchant receivables.

Multi-Chain USDC Routing

Support USDC on Ethereum, Base, Polygon, Arbitrum, Solana, and other chains while routing funds into the treasury and settlement flows your operations team actually uses.

Confirmation Tracking

Monitor incoming transfers in real time, apply confirmation thresholds by risk profile, and surface payment status to buyers, operators, and downstream internal systems.

Invoice Matching & Reconciliation

Match incoming USDC transfers to invoices, orders, or virtual accounts and keep reconciliation logic synchronized with ledger, ERP, and merchant reporting workflows.

Signed Webhooks & Notifications

Emit structured webhook events when payments are detected, confirmed, reversed, or timed out so fulfillment, alerts, and finance automation stay reliable and idempotent.

Merchant Settlement Operations

Give operators a dashboard for settlement status, exception handling, transfer history, payout exports, and accounting-ready transaction records.

Treasury & Off-Ramp Integration

Connect custodians, banking partners, or off-ramp providers so received USDC can be routed into fiat settlement, treasury sweeps, or corridor-specific payout workflows.

Refunds & Controls

Build refund flows, operator approvals, wallet screening hooks, and audit trails so USDC payment operations remain safe as volume and counterparties grow.

Compliance & Regulatory Note

Financial products involving payments, cards, accounts, stablecoins, or tokenized assets may require legal, regulatory, banking, issuing, custody, or compliance partners depending on the jurisdiction and product structure. We do not provide legal or regulatory advice. Our role is to design and build the software layer, integrate third-party providers, and implement the technical controls for onboarding, transaction monitoring, reporting, and risk management. You should work with qualified legal counsel and compliance partners to define and meet your regulatory obligations.

Frequently Asked Questions

Can I accept USDC on multiple chains?

Yes. USDC is available on Ethereum, Base, Polygon, Arbitrum, Solana, Stellar, and other chains. We build multi-chain monitoring and routing so your product can accept payer-friendly chains while still feeding the settlement and treasury flows your team prefers.

Can USDC payments be automatically matched to invoices?

Yes. We build invoice matching logic that ties incoming USDC deposits to specific payment sessions, order IDs, invoice references, or virtual accounts so finance teams can reconcile collections with much less manual work.

Can users pay from any wallet?

Yes. USDC is a standard ERC-20 (and equivalent) token. Any wallet that supports the relevant chain can send USDC to your deposit address. No special wallet integration is required from the payer side.

How do webhooks stay reliable?

We usually add signed webhook payloads, retry logic, event ids for idempotency, and clear payment-state transitions so your backend can trust confirmation, timeout, refund, and settlement events.

Can USDC be converted to fiat?

With an off-ramp integration, yes. We integrate third-party off-ramp providers that convert USDC to fiat and settle to a bank account. The conversion and banking services are provided by the licensed partner.

How do refunds work with USDC?

Refunds require sending USDC back to the original sender wallet. We build admin-controlled refund workflows where a refund is initiated, approved, and executed on-chain, with matching ledger, reconciliation, and accounting entries.

Can this integrate with accounting software?

We build accounting export pipelines that produce transaction records compatible with tools like QuickBooks, Xero, or your internal finance systems. Export formats, settlement references, and reconciliation fields can be configured for your accounting requirements.
