When retrieving the response containing the incorporation number after an incorporation filing, the document link should then be a link with that incorporation number.  Instead, it contains the temporary  (Txxxxxx) number.  So, you canāt use it to get the list of documents.
Here is an example. Note the documentsLink contains the temporary id. At this point it should contain the incorporation number so that it can be used to obtain the documents. Perhaps the commentsLink is incorrect as well, but I have not been using that.
