Payments
Zyntra OS + Adyen
Customers pay an invoice on Adyen's payment page, and the payment is recorded once Adyen confirms it.
What is Adyen?
Adyen is a payment company that takes card and wallet payments for businesses in many countries.
What you gain when you connect it
- Adyen's own payment page. The invoice opens Adyen's Pay by Link page; the card is typed there, never on our pages.
- Paid where they already look. Your customer pays from the invoice's own link or in the client portal — only on an open invoice, in a currency the provider takes.
- Recorded on its own. Once the provider confirms the payment, it is recorded against the invoice and the invoice shows as paid — nobody types it in again.
- Signed notices only. Adyen's notices are checked by their HMAC key; one that fails the check is refused.
- Captured when you choose. With automatic capture off, the invoice is paid only when Adyen says the amount was captured — once.
Who it suits
A business that sends invoices and wants them paid online, recorded without typing.
How to switch it on
- Open Setup › Payment GatewaysAn administrator who may change settings opens it in Zyntra OS.
- Enter your own accountEnter your Adyen API key, merchant account and HMAC key — from your own account with the provider. Secret keys are kept sealed and never shown again.
- Try it in test modeIt starts in test mode: you try it, and nothing real is sent, charged or recorded.
- Switch it onTurn test mode off and switch it on — from then on it works by itself.
