Hi,

please check the Redirect URL you entered during creating new client ID. The URL must be the same as is in the error message you got.

Hi, yes, you were right, the URL was not the same (the one in Google was "https...." instead of http (I don't know why).

Now I could go a little further but got another problem: teh following error message....

Hi,

you have to add this column "modified" into the table booking_google_calender in the database.

Hi, thanks for your help. It worked. But now the problem is that I make a reservation but the reservation will not be automatically written on my google calender. I have to click the button Synchronize Events. Otherwise it doesn't work. How does it functions?

Hello,

yes, it works exactly as you wrote. You have to click on the button Synchronize Events to synchronize reservation with your Google Calendar.

Oh, but that is not very useful at all !!
The users who make reservations want to see also an updated calender. The user doesn't have access to control panel to click the button Synchronize Events, let's say after a reservation is made. Only I have access to the control panel but I cannot access each day and click the button. The synchronization should occur automatically or at least there should be a button included when you confirm a reservation that says for example "update calender". So I could tell my users "after making a reservation don't forget to press the button update calender to see your reservation in calender" or something like that....
