Square and MassageBook Pay (powered by Stripe) are separate credit card processing accounts. While you are able to connect to both Square and MassageBook Pay at the same time, only one can be used as your default payment processor to record both online and in person payments from clients.
If you are connected with Square and wish to switch to MassageBook Pay as your default payment processor, you can find more information on the MassageBook Pay processor here: MassageBook Pay Overview + FAQs.
If you are connected with Square and wish to connect MassageBook Pay to receive money transfers, you can do so without interrupting your Square connection. All payments made by clients will continue to process through your connected Square account, and the MassageBook Pay connection will be used in the event MassageBook owes money to your business (i.e. MassageBook Gift Card redemption).
Connecting with MassageBook Pay
Once connected, ensure that the "Set as default" button displays next to the MassageBook Pay connection. This option must remain unselected in order to maintain Square as the default payment processor.
