Update quantities in Products

Update quantities in Products

Hello everyone.

Apart from Zoho CRM, I have a previous management system, where, among other things, the stock of the products was managed.

Also, I have an API where I bring the current quantities.

Has anyone already had success connecting with a function, so that Zoho can take that external information and update the quantities?

I've tried to do it with Flow or with a rule and a function, but I can't get it to work.

Best regards.
