Connect your account
1
Copy your credentials
Log in to your Platega account and open Settings. Copy your merchant ID and API key.
2
Add them in SellAuth
Add Platega as a payment method in SellAuth, put the values in Merchant ID and API Key, and save.
3
Add the callback URL
Copy the webhook URL shown on the SellAuth payment method page. In Platega, open Settings, then Callback URLs, and add it.
Without the callback URL, orders stay pending after the buyer pays. Changing your API key in Platega also breaks callbacks until you update it in SellAuth.
Test it
Buy something cheap from your own shop and pay it on the Platega page. The order should complete within a few seconds of the payment confirming.Fees and limits
All of the shared method settings apply, including a percentage or fixed fee or discount for choosing Platega, a minimum and maximum order amount, and a custom checkout button label and icon. Platega applies its own minimum amounts. An order outside them shows Platega’s error at checkout. A Platega payment link lasts about 15 minutes. If the buyer doesn’t pay in time, or Platega rejects the payment, the order is marked as failed and the buyer can place a new one. If Platega confirms that payment afterwards, SellAuth records it as a late payment for you to resolve rather than delivering it automatically.Refunds and disputes
Refunds are issued at Platega. SellAuth does not send them and does not change the invoice when one happens. When Platega reports a refund or a dispute on a payment, SellAuth sends you a shop error notification and leaves the invoice as it is. Record the outcome yourself with Mark as on the invoice. See Refunds and Chargebacks. Platega disputes don’t appear under Disputes in your dashboard.Troubleshooting
Payments succeed but orders stay pending. The callback URL is missing in Platega, or the merchant ID or API key in SellAuth doesn’t match your Platega account. Check both, then resend the callback from your Platega dashboard. You got a notification saying a payment could not be confirmed. Platega’s API didn’t back up the callback, or the paid amount differs from the amount requested. The order was not delivered. Check the transaction in your Platega dashboard, then complete the invoice by hand if the payment is good. The amount on the Platega page differs from the store. The order was converted to RUB, which is expected.Next steps
