The Business Key is a code stored in Punchh that is intended to be used for the purpose of integrating with your POS system. This code is the same for all admins of the same brand, and is only viewable to Punch internal accounts.
If you require a business key for your business, please contact your CSM or open a ticket with Punchh support so that this may be provided to you.
