Zoom Chatbot Webhook Not Receiving Event Messages (Validated App, No Data Received)

API and Webhooks
1

Hi everyone,

I’ve built a Webhook-only app (account-level) and I’m trying to receive Zoom Chat message events — specifically chat_message.sent.
The app is successfully validated and activated, but I’m not receiving any webhook payloads at my endpoint (Make webhook).

Setup Details

  • App type: Webhook-only (account-level)

  • Event Subscriptions:

    • :white_check_mark: chat_message.sent

    • :white_check_mark: chat_message.received

    • :white_check_mark: channel_message.sent

    • :white_check_mark: channel_message.received

  • Webhook endpoint: Make webhook (tested, returns 200 OK on manual POST)

  • Validation: :white_check_mark: Passed (Zoom displays “Validated successfully”)

  • Webhook URL uses HTTPS and is publicly accessible

What’s Working

  • App is activated in Marketplace (internal use)

  • Validation request succeeded

  • Test POST requests to the Make URL arrive successfully

What’s Not Working

  • No payloads are received from Zoom when messages are sent in Zoom Chat or in-meeting chat

  • No delivery attempts appear in Zoom’s developer logs

  • The webhook event subscriptions remain silent even with “Send test event”

I need the webhook to trigger automatically when any message is sent that contains specific keywords (like “me”) in Zoom Chat or webinar chat, so that Make can process those messages downstream. Other events work for detecting but this I am not recieving any payload for this

Hi @Ugentic
Thanks for reaching out to us and welcome to the Zoom Developer Forum
Have you tried testing with a Test url? I would suggest if you could try with soething like Svix, here is a blog on how to set it up

And try to see if the events are being received.
I will test on my end and will get back to you with an update
