A safe overview of the digital receipt integration
Approved POS companies can connect after business review, receipt-plan activation and controlled connection setup.
Integration flow
From approval to Wallet claim
- 1
Business approval
TerraGridTech reviews the business and intended receipt use.
- 2
Receipt setup
An approved receipt plan and POS access are prepared manually.
- 3
Receipt and QR
The approved POS creates a digital receipt and customer QR.
- 4
Wallet claim
The customer scans or enters the code to save the receipt.
- Connection key creationAn authorised administrator creates a POS connection key and handles it securely.
- Connection testVerify the connection without consuming a receipt credit.
- Receipt creationCreate the receipt with a stable external reference so a safe retry does not create a duplicate.
- QR and Wallet claimDisplay the customer QR; claiming the receipt uses no additional receipt credit.
Authentication and retries
Controlled access, clear retry behaviour
Authentication overview
Approved integrations use a POS connection credential. Keep it out of source code, screenshots, URLs and support messages.
Idempotent retry
Reuse the same request reference when retrying the same receipt operation so the platform can reject unintended duplicates.
