GetContacts is returning null. Why?


GetContacts is returning null. Why?

I'm using the C# support api's. Up until very recently specifying ResultSet<contact> rs = GetContact(<email address>, 1) returned a ResultSet<contact> in which I could retrieve a count of number of contacts retrieved (in this case either 1 or zero). If it retrieved 1 contact object, I could then gain access to it via rs.Results[0].


But very recently within the last couple of days invoking this api call returns null. What am I doing wrong?

Hello @Mike_Cravitz,


Thank you for reaching out to Constant Contact's API Support.


If this error just started recently then the most likely cause is Mashery is now blocking none TLS 1.2 traffic. We made an announcement back in August regarding this. Please check out the forum post we made regarding this change.
