Subscribe to events: invoice.paid, invoice.expired

Test mode

Use sk_test_* keys to test the full checkout flow without real funds. Flip to sk_live_* when you're ready for production.

How it works

1. Member selects a membership and chooses "NakoPay (Bitcoin)" as payment method
2. Plugin creates a NakoPay invoice via the API
3. Member is redirected to NakoPay's hosted checkout page (QR code + pay address)
4. On payment confirmation, NakoPay sends a webhook to your site
5. Plugin verifies the HMAC-SHA256 signature and activates the membership
6. Member gets immediate access to protected content

Subscription Webhooks

NakoPay supports recurring crypto subscriptions. When enabled, your webhook endpoint receives these additional events:

Each event payload includes the subscription id, amount, coin, interval, status, and metadata (plan name, plan ID). Renewal and past-due events also include the invoice_id.

To enable subscription webhooks, add subscription.* to your webhook endpoint's enabled events in your NakoPay dashboard at nakopay.com/dashboard/settings.
