Payments
Zyntra OS + Mastercard
Customers pay invoices by card through Mastercard's payment gateway.
What is Mastercard?
Mastercard Payment Gateway Services is the card gateway many banks give their merchants; the customer pays on Mastercard's own checkout page.
What you gain when you connect it
- Your bank's gateway. It works with the merchant account and gateway address your bank gave you.
- 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.
- Read from Mastercard. Every result is read from Mastercard itself before it is recorded.
- Tried safely. In test mode the provider's sandbox is used and no test payment ever reaches your books.
Who it suits
A business whose bank gave it a Mastercard gateway merchant account.
How to switch it on

- Enter your own accountEnter the merchant ID, API password and gateway address your bank gave you — 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.
