Fixed processing fees can make small purchases difficult to price profitably.
PAYMENT PROVIDERS
Lightning payments for payment providers.
Add a self-custodial crypto payment rail to your platform. Send, receive, and settle BTC, USDT, and USDC through one Amboss Payments API.
Build beyond traditional payment constraints.
Batch settlement and banking schedules can delay access to funds and complicate reconciliation.
Cross-border payments add FX fees, correspondent banking costs, and compliance complexity.
WHY PAYMENT PROVIDERS CHOOSE AMBOSS
How Amboss Payments helps.
Predictable pricing
Pricing tailored to your payment volume and business requirements. Talk to our team.
Instant settlement
Payments settle in seconds, not days. No batch windows, no banking hours, no weekend delays.
Cash App compatible
Customers pay Lightning invoices from their Cash App dollar balance. No bitcoin balance needed. Learn more.
Multi-asset support
Accept and settle in Bitcoin and stablecoins. Give your merchants the flexibility they need.
Built for micropayments
Enable small, usage-based payments over Lightning—for content, API calls, and digital services. Validate transaction economics with your pricing proposal.
Screening infrastructure
IP node screening and OFAC channel checks via Reflex support your risk controls. Your business remains responsible for its compliance obligations.
Cash App reported 59 million US monthly transacting accounts in December 2025—not all are eligible for Lightning. Eligibility and limits apply; unavailable in New York. Lightning compatibility, not Cash App Pay or a partnership. Sources: Block annual report and Cash App disclosures.
CHOOSING A PAYMENT RAIL
What to compare in a Lightning payment provider.
A crypto payment provider should fit your product, not force you into a separate checkout. Compare the payment experience and the operational model behind it before choosing infrastructure.
Assets and wallets
Check which assets your merchants can accept and which wallets their customers can use. Amboss Payments supports BTC, USDT, and USDC over Lightning, including compatible Cash App payments.
Custody and settlement
Understand who controls the keys, where funds settle, and when they become available. Amboss Payments is self-custodial software: funds settle to infrastructure you control.
Integration and operations
Evaluate API coverage, signed webhooks, sandbox access, reconciliation data, support, and the payment limits required by your product.
Commercial and compliance fit
Compare pricing at your expected volume and ticket size. Review supported regions and your own licensing, sanctions, and customer-protection obligations before launch.
BUILT FOR YOUR CHECKOUT
A Lightning payment flow for your platform.
Add a crypto payment option inside the checkout your merchants already use. Start with a sandbox integration, then test payment outcomes and operational requirements before accepting live payments.
- 1
Create an invoice
Your backend requests a payment for the selected wallet and amount. Show the returned Lightning invoice as a QR code or payment link in your checkout.
- 2
Let the customer pay
The customer approves payment in a compatible wallet. Keep the order pending until your backend confirms the transaction outcome.
- 3
Confirm securely
Verify webhook signatures before updating an order. Handle completed, failed, and expired payments, and deduplicate repeat deliveries.
- 4
Reconcile the order
Associate your order with the transaction ID and retrieve transaction history for reconciliation. Treat payouts as a separate integration flow.
Implementation references: receive payments, webhook handling, and sandbox setup. Keep API keys on your server, never in the browser.
SMALL PAYMENTS. MORE POSSIBILITIES.
Micropayments unlock new ways to charge.
Not every purchase needs a subscription or a large prepaid balance. Lightning gives payment providers a rail for small, individual payments—opening up pay-per-use models for their merchants.
Potential use cases include a paid article, a digital download, or metered API access. These are integration scenarios, not claims about existing customer deployments or guaranteed savings.
Example: pay-per-content checkout
A publishing platform creates an invoice for a single purchase. After verifying a completed payment, its backend unlocks the content and records the transaction against the order.
Before launching, test small amounts, invoice expiry, duplicate notifications, and customer support flows. Confirm practical payment limits and pricing with Amboss Payments; base-unit precision alone does not establish an economical minimum payment.
PAYMENT PROVIDERS FAQ
Before choosing a Lightning payment provider.
Who is this integration for?
Payment service providers, processors, and platforms that want to add Lightning to their own checkout or payment product. Your team owns the customer experience and order lifecycle; Amboss Payments supplies the payments API.
Who controls the funds?
You do. Amboss Payments provides a pure-software, self-custodial payment rail: you retain control of your keys and funds. Amboss Payments never takes custody.
Is the payment rail built for international businesses?
Yes. A software-based payment rail lets you build for customers across borders without relying on local banking hours. Availability and regulatory obligations depend on your activity and jurisdiction; self-custody is not a blanket exemption from licensing or sanctions requirements.
What does processing cost?
Pricing is tailored to payment volume and business requirements. Request a commercial proposal and assess the total cost at your expected ticket sizes, especially for micropayments. The sandbox is free to explore.
