[CENTER] The gateway is designed to be configured from the Paymenter admin panel and the Polar dashboard.
Create one base Polar product.
Connect it to the gateway.
Add your Organization Access Token.
Configure the webhook endpoint.
Let Paymenter dynamically send the correct invoice details and checkout price every time.
The setup stays simple because Polar does not need a separate product for every Paymenter package, service, addon, or invoice.
────────────────────────────────────────[/CENTER]

[CENTER]🔐 Webhook Support[/CENTER]

[CENTER] The gateway only needs the essential Polar webhook events:
checkout.created
order.paid
order.refunded
checkout.created is accepted for clean webhook delivery.
order.paid marks the Paymenter invoice as paid.
order.refunded records the refund inside Paymenter and can return the invoice to pending if money is owed again.
Webhooks are verified before any invoice is updated.
────────────────────────────────────────[/CENTER]

[CENTER]🔁 Billing Cycle Support[/CENTER]

[CENTER] Paymenter remains responsible for billing cycles and recurring invoices.
When Paymenter creates a renewal invoice, the customer can pay it through Polar just like any other invoice.
The customer returns to the Paymenter invoice page, keeping your service lifecycle clean, predictable, and easy to manage.
This extension does not create Polar subscriptions.
Every renewal payment is handled as a new one-time checkout.
