Re: C# Update Contact using API

Hi @RivkyH8,


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


In order to fully troubleshoot we would need some information that is best kept off of a public forum. Would you please send us an email at with your API Key and the endpoint that you are trying to use along with any JSON data that you are sending if applicable?
