You need to create a 'charge' to receive payments through OpenNode. A charge contains both a Lightning Network BOLT11 invoice, capable of accepting payments through the LN protocol, and a on-chain address for standard on-chain transactions.
Webhooks
In order to receive notifications when a 'charge' changes its status, you need to subscribe to the 'charge' events. You can subscribe by passing a 'callback_url' parameter on the charge payload.
Lightning Network limit
The API does not return a lightning invoice when creating a charge with an amount bigger than 4294967 sats (~ 0.0429 BTC).

}You can use OpenNode's native checkout experience by redirecting your user to the checkout endpoint:
Development - https://dev-checkout.opennode.co/ {id}Production - https://checkout.opennode.co/ {id}
If you want to build your own checkout experience you can create BIP21 + BOLT11 QR code using the uri field.
