Zoho OAuth Connector Deprecation and Its Impact on Zoho Desk

Zoho OAuth Connector Deprecation and Its Impact on Zoho Desk

Hello everyone,

 

Zoho believes in continuously refining its integrations to uphold the highest standards of security, reliability, and compliance. As part of this ongoing improvement, the Zoho OAuth default connector will be deprecated for all Zoho services that support Deluge connections.

 

This change applies to Zoho Desk and will help create a more secure, consistent, and future-ready integration experience for you.


Overview of the change  

The Zoho OAuth default connector was designed to let users authenticate once and access multiple Zoho services with a single connection. The change will let us tackle the growing technical complexity and evolving security requirements, enabling a more stable and secure integration experience. This transition will begin from December 31, 2025. (UPDATE: The timeline has been revised to January 31, 2026).

Recommended approach going forward  

For Zoho Desk integrations, we recommend switching to service-specific connectors such as Zoho CRM, Zoho Books, and Zoho Projects. Dedicated connectors are now available for each service and are designed to provide a more controlled and secure authentication experience.

 

If your use case requires access to scopes from multiple Zoho services within a single connection, a custom connector can be created to support those requirements. 

Applicability   

This change applies to any Zoho Desk portal that currently uses the Zoho OAuth connector for:

  • Custom functions
  • Integrations
  • Extensions 

Timeline and next steps  

The transition will take place in stages:

 

Phase 1

Starting 
December 31, 2025, new Zoho OAuth connections cannot be created, and the connector will no longer appear in the default services list. (UPDATE: The timeline has been revised to January 31, 2026).

Phase 2

Existing Zoho OAuth connections will continue to work for a limited period to prevent disruption. These connections will later be deprecated, with advance communication sent to users who are still using them. Zoho currently estimates at least 
12 months before the connector is fully retired. 

Conclusion 

This change is being introduced to strengthen the security and reliability of the Zoho ecosystem. We encourage Zoho Desk users to review and plan the necessary updates. We understand that this transition may involve manual effort. Adequate notice will be provided before the connector is fully retired to allow sufficient time for making the smooth transitioning.

                                                                                                                  Our data table maintains two years of data. Management wants certain report to automatically filter the report to the latest calendar week. I know I can do this manually with filters but I want the report to automatically default to the latest calendar

                                                                                                                  My company upload lots of PDF files onto Zoho. But every time we open it, it downloads the file instead of viewing it on the web page. Does Zoho allow uploaded PDF files to be rendered to view on web page yet? I've been trying to use <embed> or <object> but it cannot be loaded.  (similar thread: https://help.zoho.com/portal/community/topic/how-to-open-a-pdf-file-of-a-view-in-preview-mode)

                                                                                                                  It's rare, but occasionally it would be a good feature if I were able to overlap reports, either fully or partially in the Dashboards. Also, then having the ability to move objects to the front or rear, or make them transparent/translucent would be good

Sometimes you are looking for a particular name that gets lost in a bunch of less important

We have found there is no support for Cisco Webex Calling however? Is there a way to enable this or are there any apps which can provide this? Thanks!
