I have a large product database on the website and want Zoho to read the products from it into the the Zoho Products module. I would want this to run as a timed function once per day that is initiated by Zoho. 

I want to avoid having the website push updates to Zoho because their OAuth is so painfully difficult. What would be nice is to have Zoho submit a request for all products updated or added in the last 24 hours and then process the JSON generated by the website, upserting the records as appropriate.
