  @DorisMendez We disabled TLS 1.0 yesterday. See this post:

  I don't know a lot about C#, but I believe you need to either update .Net to a more recent version or set up your integration to use TLS 1.2.

  I ran into similar situations the past few months with other providers' various API endpoints. So I recently upgraded my LS Retail code to use TLS 1.2.
  
  If you upgrade to .NET 4.7.1 then TLS 1.2 should be enabled by default without doing anything. Otherwise in your C# code you can specify TLS 1.2 for any classes by including this line where your classes are instantiated or methods are called:
  
  System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
  
  Hope this helps!
