Because ClassPass is in charge of the booking for your studio through the integration, they will not require customers to sign the studio's Terms & Conditions, Health Waivers, or any other required documentation.
The best solution for this, we suggest setting up a Booker icon for the ClassPass series so you can easily identify ClassPass customers in your zingfit account.
Once you have a Booker icon in place, you can use a paper waiver or a third-party solution to collect the required signatures to ensure the studio has all the required documentation prior to the class.
