Are my payment gateways (Klarna, Stripe, Adyen…) compatible with Hyvä?

Almost all major gateways have working Hyvä Checkout adaptors as of mid-2026. The current state:

• Klarna: official Hyvä Checkout module shipped by Klarna directly. Works for all Klarna products (Pay Now, Pay Later, Slice It). Free.
• Stripe: official Hyvä-compatible Stripe module from the Stripe team. Apple Pay, Google Pay, ACH, BNPL options all work.
• Adyen: official Adyen Hyvä Checkout adaptor. Drop-in supports all 100+ Adyen payment methods.
• PayPal Braintree: works via Hyvä Compatibility Module bridge + Magewire wrapper. Smooth integration.
• Mollie: community Hyvä Checkout module, well-maintained. Covers iDEAL, Bancontact, Sofort, SEPA.
• Affirm: community port available, used in production on 3 of my US-based migrations.
• Authorize.net: works through Hyvä Compatibility bridge. Stable on legacy implementations.
• Amazon Pay: official Hyvä module.
• Apple Pay direct (not via Stripe / Adyen): works through Magento Vault module + Hyvä Magewire wrapper.

The gateways that are not well-supported yet: a handful of regional payment providers (some Latin American + APAC processors), some legacy fraud-screening extensions, and a few exotic enterprise integrations. I check your specific gateway list in step 1 (Audit Luma) and flag any that need a custom port. Add 1-3 weeks per non-supported gateway.
