Payment Button

Accepting payments on websites

Suggest Edits

You can facilitate payment on your site and receive payment globally using our API, our JS script, SDKs or WordPress and Wix plugins.

Embedding a payment button connected to the API via these means generates a payment checkout popup and allows customers to scan the QR code to make payment on any crypto wallet available to them.

Checkout Pop Up

After a checkout has been created using the button, it generates a pop up on the website without redirecting the user to another site. The payment checkout is consist of a bip21 QR that has both a lightning and on-chain address added to it. It also has then displayed so users can copy them.

Minimum on-chain Amount

Onchain addresses are only generated for payments above $5. Payments less than $5 will only generate a lightning invoice.

Callback

After successful payment of a checkout payment, a webhook event is sent. Either checkout.received.paid for full payment or checkout.received.underpaid or partial payment. This event can be used to change the status of a payment order on your platform or credit a customer's account.

🚧

Verification of Webhooks

All webhook events should be verified to ensure that these webhooks are from Bitnob before performing any action.

Redirect to Success URL

When creating a checkout, a successUrl, after successful payment, Bitnob redirects users back to your site, using the set successUrl. A successUrl should always be set so as to allow the user to continue the transaction on your platform.
