Wix Bookings: paymentTypes (Corvid) "wix-online" and in person?

I allow my clients to pay both online and in person when booking my services online. When coding my paymentTypes, should I just use the following?

let options = {
“paymentType”: “wixPay_Online”,
“couponCode”: “thecouponcode”
};

or, should “wixPay_Offline” be included?

Have a read of the Wix Bookings API reference as it will explain it there.

Plus this Wix Bookings support page which you can add additional code to it to indicate which payment is to be made.

Although note that you can already set your prices to be online, in person or both.

Also, you’ve probably already done this, however just checking, to setup payments first.
