I recently signed up with Online Checkwriter to print my own checks on my printer.  Under the integrations tab in Online Checkwriter, it claims that it integrates with Zoho Books.  I even went through their process and "connected" it to my Zoho Books.

However, when I go into my Zoho Books, I do not see it under my Integrations and Zoho does not offer it under their apps.  How can I connect these two programs so I can log my checks in Zoho and print them using Online Checkwriter?
