The WebService is accessible through the SOAP protocol
"Login" method was removed from this document and is to be considered deprecated starting from MailUp release 7.4. It was replaced by LoginFromId method. If you are still using Login, don't worry: Login method is still available, even if not recommended for new integrations, and returns a response that is equal to the one that is returned by LoginFromId. Signature of old Login method is string Login(string user, string pwd, string url), where URL is the console URL without http://
This method is available only from MailUp release 7.4 and it's very similar to the previous one (Login) but it allows to specify an account ID instead of a console URL. The main benefit lies in the fact that a URL limits the use of the infrastructure, whereas a fixed reference like the console ID makes it easier to move the administration console on a higher-performing hardware, if needed. There would be little or no malfunction, as the customer's applications would keep on working after the operation.
