The project is to create a php script to synchronize Google contact and mysql table contacts with v3 API.
The user must have a choice before synchronize.
1/ Add, update and delete [url removed, login to view] contacts who are not in Google contacts.
2/ Add, update and delete Google contacts who are not in [url removed, login to view] contacts.
3/ Add just new contacts who are not in the two parts.
User is already connected to Google account and we have his token session in cache.
Thank you for you proposals.
