title: Getting transactions using plaid on a mortgage account
body: <p>I'm using plaid to get my bank transactions. I have a mortgage account for which I have working access tokens. I'm able to make an API call to that bank account using the python SDK:</p>
  
  <pre><code>retDict = self.client.Transactions.get(self.tokens[bank_name], start_date.strftime('%Y-%m-%d'), today.strftime('%Y-%m-%d'))
  </code></pre>
  
  <p>I get a valid response with the right bank info, the right balance, but no transactions no matter the start_date and today values. This code works just fine with other institutions (checking account, credit card account). Is there something that needs to be done differently for a mortgage account?
  Is this behavior expected?</p>
