For a POS to properly communicate with Punchh, the following endpoints must be whitelisted/allowed through a firewall.
pos.punchh.com
isl.punchh.com
To test these, on your Back of House computer, where your POS is installed, open up an internet browser and go to:
pos.punchh.com/ping
isl.punchh.com/ping
If you receive an "OK" message - all good!
If you receive a message that the connection failed - please refer to the following whitelisting documentation.
Network Firewall and Anti-Virus Setup
PUNCHH Firewall rules. Confirm that the following FQDN (Fully Qualified Domain Names) endpoints are properly whitelisted in the site's firewall/router
