Ok It's finallly working, Thanks Dam for attending the support ticket!
For those out there who want this integration to work, This is what is required:
docs.joomdonation.com/osservicesbooking/...calendar-integration
Follow the above manual as much as you can with the following exceptions and additions:
Enable the OS Gcalendar plugin: System > Plugins > OS Services Booking - Google Calendar sync
Create a JSON KEY in Google, download it and upload it into your components -> com_osservicesbooking folder
Note the FULL name of the file including the extension, you'll need it later.
In google calendar make sure to add the google address as "Shared with":
for example: osbcalendar@YOURPROJECT-463807.iam.gserviceaccount.com
Employee settings look like this:
Google client ID
111108120327633551814
Get this from your Google App Credentials page. - a.k.a. "Unique ID"
App Name
osbcalendar
This is the name of the App you create on Google. You need to create a Google `App` so that OSB is allowed to talk to your calendar(s) - under Service account details and then "Name"
Service account email
XXXXXX@gmail.com
Get this from your Google App Credentials page. You will also need to share your calendar to this email address.
"Principals with access to this service account" tab
Google key
YOURPROJECT-163027-a532352a8sc2.json
Please enter your Google JSON file in full including the extension, which should be located in the folder components -> com_osservicesbooking
Google Calendar ID
XXXXXX@gmail.com
This is obtained on the Google Calendar 'Calendar Settings' screen, Calendar Address section. (Same as the other one above)
*If you get a weird bunch of characters like � ���� on your form then delete default.zip in folder: components -> com_osservicesbooking -> classes -(Don't rename, just delete!)
And there you go! Integeation works for new orders (Old bookings unfortunately will not be transferred to the calendar)
It wasn't easy but it's possible, it would be nice to update the outdated instructions, seek and you will find!
