The package: google-api-php-client-master.zip is included in OS Services Booking package, you just need to upload the package into folder: root -> components -> com_osservicesbooking and extract it.
unfortunately no, that's why I didn't get any further, unfortunately OS booking ... cannot be used without gcalender ... You can then also enter bookings via telephone if you have to transfer the OS b ... manually from the mails to the calendar
Ooooooooh. You're telling me that "GCalendar" is a separate component! I had no idea. JoomDonation refers to it in the OS Booking documentation but never explicitly states that it is a separate component. That's frustrating. After all this time I'm just now learning this.
I look and it "Easy GCalendar" was last updated in Dec 2018! It's old. The last blog entry is May 2017!!
So Does JoomDonation expect me to pay "Daniel" at GCalendar $15 per year so I can use JoomDonation's OS Booking component which I also pay $39 per year for?
