John,

I think you should be able to get this to work. You can actually set any conditions on your REST model that the REST API allows you to. For example, let’s say that I have a table of Accounts with their billing country codes, and I want to get the name of the country to show in a drawer (an admittedly contrived example, but it somewhat parallels your use case). I can use a REST connection to https://restcountries.eu/ to look up the name of a country based on it’s two letter code. To do that, I added a DrawerCountry model, and it’s Data Source URL is /rest/v2/alpha/{{code}}. Because I’ve added {{code}} to the URL, I can then go to the URL Merge Conditions section of that model, hit the plus, and then select code to add a filterable condition on it. The URL Merge Parameters only show as options what you’ve put in the URL. I then added a drawer action to my table, and added two actions to the before load actions of the drawer - activate and set value of model condition (set the {{code}} parameter to {{BillingCountry}}) and then queried the DrawerCountry model (query behavior is get more - merge in new rows with old). In your situation, you’ll need to check that Zoho allows you to pull results back based on your criteria, but if it does you should be good to go. Let me know if any of that was unclear or if you run into problems.
