I haven't run into this before, but I have a system that I need to Post data to and they are telling me that they don't use any level of authentication. Specifically, they said in their email to me that:
"Usually we just had a hash that you pass and/or we restrict the IP the posts come from."
My question is, is it possible to build a connection to this system if no authentication is being used on their side? Is so, what option do I select when building the authentication for the connection in Celigo?
