How it works
- 1
Generate credentials
Open Settings → Integrations in the Business Portal. You’ll receive a Merchant ID, an API Secret and a Webhook Secret — one set that works for every integration path.
- 2
Create a payment session
Your server calls
https://api.scanandpay.com.auwith the order amount and receives a payment session with a QR Pass to display at checkout. - 3
Verify the webhook
When the customer pays, Scan & Pay sends a signed event to your endpoint. Verify the
X-Scanpay-Signatureheader with your Webhook Secret, then mark the order as paid.

Libraries for Node.js and PHP that handle session creation, webhook signature checks and retries for you. The Node.js package also includes a ready-made React checkout component.

Get your credentials
- 1Sign in to the Business Portal.
- 2Open Settings → Integrations to view your credentials.
- 3Copy Merchant ID, API Base URL, API Secret, and Webhook Secret.

Treat your secrets like passwords. Regenerate them only if they may have been exposed — every connected integration stops working until it has the new pair.
