Google Contacts Carddav Url
google-app-engine
Solution
The URL at this moment is:
https://www.googleapis.com/carddav/v1/principals/YOUR@gmail.com/lists/default
But the client you're trying to connect from should not be using this permanently, but instead discover the correct URL by sending a `PROPFIND` to `https://www.googleapis.com/.well-known/carddav` as described in the Developer's Guide.
Anyway, Roundcube would have to support OAuth2 authentication, not user and password, to be able to connect properly, which I don't believe it does.
Problem
I would like to sync my google contacts into roundcube. I already installed 2 plugins (calendar sync with caldav is working like a charm with url, user and password) but I cant find the correct url for the carddav service. Does anyone knows it? Thank you Moritz
