Accept card payments through the provider’s hosted checkout.
Before you start
A K&H merchant agreement, merchant identifier, your signing private key and the gateway public key.
Set up
Open the App Store, install K&H, and open its settings. Save the merchant settings and validate them. Validation checks that the settings are complete; only a test payment proves the account works. Complete successful, declined and canceled test payments, then confirm the order outcome in Poltura and the provider account before using live credentials.
Settings
Use the account identifiers and credentials issued for this connection. Save secret values only in the app’s credential fields. Keep test and production account details together.
Scope and limits
Use matching environment credentials and keys. Complete the bank’s acceptance checks before production.
Forint payments are charged in whole forints. A full refund before settlement reverses the payment. After settlement, refunds can be full or partial, and can repeat up to the paid amount.
K&H reports a payment only when the shopper returns to the store. If a shopper pays and closes the browser before returning, no order is created: check the K&H account and contact the shopper.
Troubleshooting
Check that the app is enabled, required settings are saved and the external account has the necessary access. If an operation has an uncertain outcome, check the external account before repeating it.
