Payment Links — no code, fastest to launch

Create once from the Dashboard or with one API call. Customer opens the link, pays, and is redirected to your successUrl.

• Email, Slack, social, QR code — any channel works.
• Supports all payment methods: cards, Apple Pay, Google Pay, local bank transfer.
• Minimal setup: product name + price + currency.

Create a subscription offer, share a link. Inflow handles retries, trial periods, entry fees, and waitlists.

• Discord role assignment on active subscription.
• Customize billing interval, trial period, entry fee.

SDK (iframe card form) — embedded checkout on your site

Mount a PCI-compliant card form in your page. The customer never leaves your domain.

• React: <CardElement /> component.
• Vanilla JS: provider.createCardElement().mount().
• 3DS modal opens automatically when required.
• Cards only — Apple Pay, Google Pay, and local bank transfer are not available via SDK.

Server-to-Server — full API control

• Mobile apps, headless frontends, marketplaces.
• Save and reuse customer payment methods (savePaymentMethod, useCustomerPaymentMethod).
• All payment methods available: cards, Apple Pay, Google Pay, local bank transfer.
• Must be enabled for your account — contact [email protected].
