There are many possible causes for this error, but most commonly
there is a problem with the structure or content of XML your application
provided. Carefully review your XML. One simple test approach is to
perform a GET on a URI and use the GET response as an input to a PUT for
the same resource. With minor modifications, the input can be used for
a POST as well.
This is an authentication problem. Primary reason is that the API call has either not provided a valid API Key, Account Owner Name
and Associated Password or the API call attempted to access a resource
(URI) which does not match the same as the Account Owner provided in the
URL Not Found
The URI which was provided was incorrect. Compare the URI you provided with the documented URIs. Start here.
There is a problem with the action you are trying to perform.
Commonly, you are trying to "Create" (POST) a resource which already
exists such as a Contact List or Email Address that
already exists. In general, if a resource already exists, an
application can "Update" the resource with a "PUT" request for that
Unsupported Media Type
The Media Type (Content Type) of the data you are sending does not
match the expected Content Type for the specific action you are
performing on the specific Resource you are acting on. Often this is
due to an error in the content-type you define for your HTTP invocation
(GET, PUT, POST). You will also get this error message if you are
invoking a method (PUT, POST, DELETE) which is not supported for the
Resource (URI) you are referencing.
To understand which methods are supported for each resource,
and which content-type is expected, see the documentation for that
There are many possible causes for this error. The problem may be
with the API itself, but most commonly there is a problem with the
structure or content of XML your application provided. Carefully review
your XML and the URL you are using.
