Error during Authorization on Zoom for Lightning Salesforce APp

Zoom Apps
1

Hello All,

I’m Facing below issue when Authorizing to my account from salesforce.

After successfully authorizing Zoom managed package in one Salesforce org, I’m unable to authorize the same package in a different org. Previously, this worked fine.
I would cancel the authorization in Org A, switch to Org B, and authorize successfully. Now I’m getting an OAuth error.

Error : OAUTH_AUTHORIZATION_BLOCKED
error_description=Cross-org+OAuth+flows+are+not+supported+for+this+external+client+app
Internal Server Error

Steps to Reproduce:

  1. Install Zoom managed package in Org A
  2. Authorize via OAuth (successful)
  3. Cancel authorization in Org A (via Zoom admin or Connected App settings)
  4. Switch to Org B (different Salesforce org)
  5. Attempt to authorize Zoom package in Org B
  6. Receive the above error; authorization fails

What I’ve Tried:

  • Cancelled authorization in the original org
  • Cleared browser cookies/cache

We have a customer having the exact same issue.

OAUTH_AUTHORIZATION_BLOCKED

Cross-org OAuth flows are not supported for this external client app

Salesforce Connected App: Zoom Contact Center OAuth
Salesforce environment: Sandbox
Connected App status: Installed/Allowed
User: Salesforce System Administrator
OAuth app: Successfully visible in Connected Apps OAuth Usage
Browser: Also reproduced in Incognito

We have tried with incognito. We also checked the role of the integration account, and it has all the right permissions. Again, this worked and just stopped working. We cannot reauthorize. We also deleted the app and tried to reauthorize again, and we also noticed that the same problem is happening with Zapier and other customers. Can someone look at this ASAP?

Same here Waiting for a response,

The issue is that Zoom for Salesforce is working in Production, but we are unable to authorize/connect Zoom with any Salesforce Sandbox org. I tested this in both our existing QA Sandbox and a brand-new Sandbox, and both return the same error:
OAUTH_AUTHORIZATION_BLOCKED: Cross-org OAuth flows are not supported for this external client app
Since we are using the standard Zoom managed package, and the same error occurs for multiple users and multiple Sandbox orgs, it does not appear to be user-specific.
I also found a recent post on the Zoom Developer Forum where another user reported the same error when trying to authorize the Zoom managed package in a different Salesforce org

We just started experiencing this exact same issue in our sandbox org. Was successfully connected, now refuses to reconnect. If anyone has a solution please post it here
