Error in URL Validation for Event Subscription in Zoom Marketplace

[javi_]

Hello,

I am trying to integrate Zoom Webhooks with an external server using the n8n platform to validate a URL in the event subscription section of the Zoom App Marketplace, but I am continuously experiencing an error in the URL validation process.

1. Problem Description:

-When entering the webhook URL into the event subscription form in Zoom App Marketplace, I receive the message: "Error in URL validation. Please try again later."

-The URL I am using is: https://n8n-n8n.ap5gnp.easypanel.host/webhook/{WEBHOOK_ID}.

-I have successfully tested this URL using Postman. The webhook responds with the correct token (plainToken and encryptedToken), but the Zoom platform still fails to validate the URL.

2. Steps Taken:

-I have configured a workflow in n8n that handles Zoom URL validation.
-I manually tested the webhook with Postman to ensure the webhook response is correct (I receive a 200 OK status code and the tokens in the expected format).
-I reviewed the Zoom Marketplace documentation, but I couldn’t find additional information to resolve the issue.

3. Technical Setup:

-I am using an external n8n server with the URL mentioned above.
-The webhook response is set to return the encrypted token as per Zoom’s URL validation specifications.

4. Expected Outcome:

-I would like to confirm if there are any additional restrictions for URL validation or if there could be an issue on Zoom’s end preventing the webhook validation.

Thank you for any guidance on this matter to help resolve this issue as soon as possible.
