These are the providers you can plug in. We list exactly what we offer. If a rail isn't on this page, the Cloud doesn't have it yet, and the open-source SDK is the way to wire it up on your own.
Connect one, two, or all four. Turn them on and off in the dashboard whenever your customer base changes. The buyer's picker shows only the ones you turned on.
Cards, Apple Pay, Google Pay.
Stripe's hosted checkout page, the one most buyers have already seen. Money lands in your own Stripe account; we never see your secret key.
PayPal balance, cards, Venmo, Pay Later.
PayPal's hosted approval flow. The buyer signs in on PayPal's own page; we never see their PayPal credentials. The money lands in your PayPal account.
Card processing with your own merchant account.
Older US card gateway, popular with merchants who came up before Stripe. If you already have a merchant account, or your bank or credit union is wired into Authorize.Net, this rail lets you keep that relationship.
Cards via Square Payment Links.
If your business already runs on Square at the counter, this rail lets your online buy buttons settle into the same Square balance and the same dashboard.
Crypto. Hundreds of coins. Monero included.
Crypto checkout that takes the coin your buyer wants and converts to the one you want to receive. US-friendly. NOWPayments holds the funds briefly during settlement, then forwards them to your wallet. As close to a custody-free rail as the list gets.
Cash. Check. Goldbacks. Whatever shows up in your envelope.
The dashboard mints a reference code, shows the buyer your mailing address, and waits. When the envelope arrives, you mark the transaction received. The buyer gets the same confirmation page as the card flow.
Four categories. The rails that cover each one. Use this to decide which providers your audience actually needs.
| Category | Stripe | PayPal | Authorize.Net | Square | NOWPayments | Pay by mail |
|---|---|---|---|---|---|---|
| Credit and debit cards | ✓ | ✓ | ✓ | ✓ | ||
| Wallet apps (Apple Pay, Google Pay, PayPal, Venmo) | ✓ | ✓ | ✓ | |||
| Crypto | ✓ | |||||
| Cash, check, Goldbacks, anything mailed | ✓ | |||||
| Subscriptions via the hosted buy button | ✓ | ✓ | ||||
| Subscriptions via your own checkout (using the webhook directly) | ✓ | ✓ | ✓ | ✓ |
Specific features inside each category (which BNPL options Stripe shows where, which coins NOWPayments accepts, and so on) live in the cards above. Region rules belong to the provider, not to us.
Two subscription rows, on purpose. The hosted buy button works for Stripe and PayPal because both have a redirect flow that sets up the subscription end-to-end. Square and Authorize.Net don't have that. Their subscription APIs need the merchant's page to collect the card itself (Square Web Payments SDK, Authorize.Net Accept.js). If you're willing to do that on your own page, our webhook + dashboard + status endpoint still handle the result like any other rail. See Use it without the buy button in the docs.
The Cloud's list is short on purpose. The open-source SDK is the way out, both for rails we haven't added yet and for the day you'd rather not depend on us at all.
The SDK has a few extra rails the Cloud doesn't surface yet, including Coinbase Business, self-hosted Monero, and Cryptomus. Point it at your own server and you get the same one-callback shape without going through us. If we ever shut down, that same setup keeps your site working.
Open the SDK on GitHubWe add Cloud rails on real demand, not guesses. If a provider would unblock you, send a note. Rails that already exist in the SDK usually take a couple of weeks to land in the Cloud.
Email the teamFree tier covers most sites. Sign in, paste your provider keys, and the buy button picks them up on next page load.
