Meeting SDK Type and Version

  • SDK Version: v7.0.2.38969
  • App Name: LINKLET for THINKLET
  • App ID: uQVP1qdJQm6wo1vN1fQL_g

Description

Our application, LINKLET, uses the Zoom Meeting SDK to join Zoom meetings from a dedicated device.

The device itself does not have a Zoom account. Instead, it joins meetings hosted by our customers as an anonymous guest participant.

However, starting on July 7, 2026 (JST), the device suddenly became unable to join meetings as an anonymous guest participant. This issue is currently impacting our production service and our customers.

    • We continued operating our production service without making any changes to our implementation.

  • July 7, 2026 (JST)

    • Anonymous guest participants suddenly could no longer join meetings hosted by external Zoom organizations.
    • No changes had been made to our application before this issue occurred.

Error

Anonymous guest participants can no longer join meetings hosted by external Zoom organizations.

The issue started on July 7, 2026 (JST), without any changes to our application.

We would like to know how to resolve this issue.

During our investigation, we became aware of the “Anonymous Join Exception” request in the Marketplace.

We do not recall receiving prior guidance that this request would be required for our application. We would appreciate it if you could also advise whether this is related to our issue.

Thank you for bringing this to our attention. Please submit the anonymous join exception request, including your reasoning and a detailed description of the app’s use case.

Thank you for your prompt response and for your guidance.

Before seeing your reply, we had already submitted the Anonymous Join Exception request on July 7, 2026 (JST).

Since we submitted the request before receiving your guidance, our submission did not include our application description or a detailed explanation of our use case. We would therefore like to provide that information here.

We provide a service that enables video communication through Zoom using our self-developed neck-worn wearable device, THINKLET.

For more information about the wearable device, please see:

https://static-connected-worker.thinklet.fd.ai/support/en/index.html

Our use case is as follows:

  • A user with a Zoom account creates and starts a Zoom meeting.
  • A client application built with the Zoom Meeting SDK is installed on the THINKLET device, allowing the frontline worker wearing the device to join the meeting.
  • For security reasons, the THINKLET device itself does not have its own Zoom account.
  • Therefore, the device joins the meeting as an anonymous guest participant.

As described in our original post, we had previously contacted Zoom Support regarding the Meeting SDK authorization changes and were advised that our application would not be affected and that no additional action was required.

Because of that guidance, we were not aware that an Anonymous Join Exception request would be necessary.

This issue is currently affecting the service we provide to our customers. If possible, we would greatly appreciate it if the review of our Anonymous Join Exception request could be prioritized.

Please let us know if any further information is required.

Thank you very much for reviewing and approving our request.

We have confirmed that our application is now able to join external Zoom meetings successfully, and the issue has been resolved.

We appreciate your prompt support.
