We have a Zoho one account which we have integrated with an SAS educational product, sold on a subscription model, using webhooks and API calls. We make some use of custom fields and cross module lookups and relationships. We utilize CRM, Books and billing and also make use of Zapier.

We are trying to improve our devops processes and currently don't really have a dev environment on the Zoho side. How can we achieve this in a cost effective manner, creating pretty much a duplicate of our current live Zoho environment?
