Anonymous JWT SDK Join External Meetings

[Riddhi (PHP Master)]

Question:
Is it possible for anonymous (no-login) users to join meetings hosted on another Zoom account using only an unlisted JWT-based Android Meeting SDK app, or is OAuth authentication (or a WebSDK workaround) required?

Environment

• Meeting SDK: Zoom Android SDK
• Version: 6.4.5.29521

Setup

1. Zoom Account One

   • Created a Meeting SDK (JWT) app in the Zoom Marketplace
   • Published the app as Unlisted
   • Using its SDK Key & Secret to generate JWT signatures server-side

2. Android Client App

   • Integrates the Zoom Android Meeting SDK
   • No user login or OAuth required in the client
   • Displays a list of meetings (Name + Meeting Number) fetched from our backend—these meetings belong to another Zoom account
   • On user tap:
     1. Retrieve the meeting password from our server
     2. Generate a JWT-based SDK signature on the server
     3. Call joinMeetingWithParams(...) in the Android SDK

---

Current Behavior

• Success: Joining meetings hosted by Account One ( Mine )
• Failure: Joining meetings owned by any other Zoom account always fails with error code : 63

---

Question

1. Can truly anonymous users (no login/OAuth) join external-account meetings via an unlisted JWT Meeting SDK?
2. If not, must I switch to an OAuth-based SDK app or embed the WebSDK (e.g., in a WebView) to support guest participants?

@Riddhi the application must be published and approved for cross account join.

Do ensure that you are using the production credentials after the application is approved.
