415 Unsupported Media Type

[ReneeJ39]

I am trying to update a users List Subscriptions from a form on our website..

I first do a Get to get the ContactID then do the PUT to this address and update Lists:

https://api.constantcontact.com/ws/customers/rplibrary/contacts/8365

Why would I be getting this error? Does my xml look ok?

I have tried both "ACTION_BY_CONTACT" and "ACTION_BY_CUSTOMER"

Sorry.. I found my own solution to the issue.. It was the Content-type not being set correctly..

I'm using ASP and I was checking for a POST and not a PUT to include the Content-type

I HAD:

If strMethod = "POST" Then
     objWinHttp.setRequestHeader "Content-type", "application/atom+xml"
End If

Changed TO:

If strMethod = "POST" OR strMethod = "PUT" Then
     objWinHttp.setRequestHeader "Content-type", "application/atom+xml"
End If

Ah, you beat me to the punch. Your XML seemed to be right, but I recreated the issue in RESTClient by submitted the request without the Content-type set in the request header.  I was just about to suggest you verify that this header was corrected set. Since you've already discovered that, however.  Let us know if you have any other questions.

Cheers,
