We are submitting a recurring payment and the output response is NULL rather than an error code. We're not sure how to handle this as we can't tell where the break is.

This sounds like a problem in whatever code you are using. The API itself does not return "NULL" and will always return an XML response. I would recommend figuring out where the NULL value is actually originating.
