Due to the intricate nature of the API, errors can happen; whether it be from Access Collins' side or from Zonal's side. Things to check before contacting Collins support:
If there's a date against the booking.
If the payment is completed and not pending.
If it's definitely a payment and not a card authentication.
If you checking for it on the till only on the date of the booking, because payments get pushed to the till on the date of the booking.
If the booking date passed, because If the booking date has passed it won't push to till.
If everything should be in order, please contact Zonal first to see if there is an error with the connection, if not, reach out to us, and mention your site name and booking reference and our team can check if a push to the till failed, and why.
For more information on Zonal integration please see the Design My Night Developers guide under the Zonal Integration EPOS Integration session.
