Accessing "Developer Edition - Zoho CRM" over CRM API

Accessing "Developer Edition - Zoho CRM" over CRM API

Hello!

Like the title says I want to access the developer edition of the CRM over the API. It that even possible? And if yes, how? The problem is, that I created custom modules and cannot see them when querying the API. I suppose that the CRM API only connects to the production environment. I also could find any specific URLs for the developer edition to access over API, like:

production: http://www.zohoapis.eu...
developer: https://developer.zohoapis.eu...

Thanks in advance!
