How are documents edits saved in host application servers?
Zoho Office Integrator allow partners and businesses to save the document content back to their storage servers through "webhook". Documents are saved in your storage servers from Editor when user click save button.
A webhook is a publicly accessible Web URL/Service that fetches the content of the updated document from Zoho Office Editors and saves it to partner's storage server.
In order to use the webhook/saveurl, partners should fulfill the below requirements:
Partner's remote storage servers need to expose one of their ports - port 443 (HTTPS) or port 80 (HTTP) - from their location, for Zoho to push the document content back.
