What the plugin does
Built so every invoice is paid exactly once
Verified payments
Signed webhook plus a server-to-server status check of amount and currency before the invoice is marked paid.
Automatic recovery
Scheduled status checks catch a missed webhook, and you can re-check any invoice from the admin.
USDC payouts
Payouts arrive as USDC on Polygon. Choose who pays the processing fee.
Settings
The same settings on every platform
Every PayLio plugin uses the same settings, so switching platforms or running several shops stays simple.

Paymenter FAQ
Which payment methods do customers get in Paymenter?
Customers pay by Visa or Mastercard, and with Apple Pay, Google Pay or local methods where the provider handling the payment supports them for the customer's country and amount. The PayLio checkout only shows the options that fit.
When is the invoice marked as paid?
Only after PayLio has confirmed the payment server-to-server. The plugin receives a signed webhook, asks the PayLio API for the payment status and checks amount and currency before it marks the invoice as paid. A lost webhook is caught by the plugin's scheduled status check.
What do I receive and when?
Your payout arrives as USDC on Polygon in the wallet from your PayLio dashboard, or in the payout wallet you set in the plugin. You can choose whether the processing fee is included in your price or added to the customer's total.
Does the customer come back to my shop after paying?
Yes. Once the payment is confirmed, the PayLio checkout shows a "Back to" button and returns the customer to the invoice page after a few seconds. That page checks the status itself, so arriving there never marks the invoice as paid.
Does card data touch my server?
No. The customer is redirected to the PayLio checkout and pays on the provider's page. Your shop only stores the PayLio payment id and status.
