QR Code

We have provided a new QR endpoint /v2/diamonds/{diamond_id}/qr (reference) which allows the grading lab to link the grading report and/or website to Tracr Diamond Experience.

The QR code is unique to each diamond.

Please note:

• Diamonds need to be unlocked by the participant prior to the grading lab retrieving the QR Code for a Tracr diamond.

Required Data:
