Synchronizes (updates) the contacts in the account with the data from a list of contacts and returns a detailed report with stats and validation errors. This method is meant to update large sets of contacts while „Create Contact“ and „Update Contact“ are used to update single contatcs only. With this method, e.g. flags for contact filters can be updated to update the set of contacts that shall receive a certain mailing.

Duplicates (e.g. contacts with the same email address when the email address is the primary identificator) are nor allowed in one call and will be ignored as it is not defined which one should possibly override the other.
