**Description:** We are integrating Zoom meetings within Salesforce using a Visualforce (VF) page that hosts the Zoom Web Client ( [Zoom](https://zoom.us/wc/) `...`) inside an iFrame.

**Current Behavior:**

- The Zoom meeting successfully loads within the Salesforce Visualforce iFrame.

- Users can join the meeting and view the Zoom UI.

- Audio and video controls are visible, however:

**What We Tried:**

- Verified browser permissions for camera and microphone.

- Added iFrame attributes like `allow="camera; microphone; display-capture"`.

- Confirmed HTTPS on Salesforce and Zoom URLs. please find the below url for your reference.

**Additional Issue:** We also attempted to use the **Zoom Web SDK** for integration, but the SDK file size is **18 MB** , and Salesforce static resource limit is **5 MB** , so we cannot upload it directly.

### **Questions:**

1. Is embedding the Zoom Web Client ( [Zoom](http://zoom.us/wc/) …) inside an iFrame supported?

2. If not, is the **Zoom Meeting SDK for Web** the recommended approach for Salesforce integration?

3. How do we handle the **SDK file size limitation** in Salesforce? Any best practices for splitting or hosting externally?

4. What is the correct way to configure iFrame permissions (`allow` attributes) for camera/mic access?

5. Are there any additional steps for cross-origin isolation or SharedArrayBuffer when embedding the SDK page?

**Goal:**  
Enable camera and microphone access for users joining Zoom meetings from within Salesforce and resolve SDK size limitations.
