I am sharing the response here too for anyone running into this issue: The endpoint URL needs to be publicly accessible, otherwise Zoom won’t be able to reach your server to send the chatbot slash commands / actions / webhooks. ---

Hi @elisa.zoom @tommy , the endpoint URL is now publicly accessible. But the public url needs to have correct authentication to access. May I know do you provide solution about this case? Where can I config the authentication header in your developer portal? ---

Hey @boting.ding Here is a link to our docs on Webhook Endpoint URL requirements [https://developers.zoom.us/docs/api/rest/webhook-reference/#webhook-endpoint-url-requirements](https://developers.zoom.us/docs/api/rest/webhook-reference/#webhook-endpoint-url-requirements) If you want to verify events with your own headers, you can do that: [https://developers.zoom.us/docs/api/rest/webhook-reference/#verify-with-your-own-header](https://developers.zoom.us/docs/api/rest/webhook-reference/#verify-with-your-own-header) ---

Hi @elisa.zoom , please specify where can I config it in my developer portal regarding my chat bot application. My problem is the post api regarding behavior of sending messages in the chat room. What you post is about event notification. I don’t get the point of the relation between my problem and the solution you provided. Could you explain more? ---

Hi @boting.ding I see, sorry about that, I am having a little bit of a problem understanding your queries. So to send messages in a chat channel or to a user, using a Team Chat app you will have to make a post request to the [Send messages endpoint](https://developers.zoom.us/docs/team-chat-apps/apis/#operation/sendaChatMessage) and pass the chatbot\_token in the authorization headers (generated making a post request to our oauth endpoint using the credentials associated with your app) [https://developers.zoom.us/docs/team-chat-apps/send-edit-and-delete-messages/](https://developers.zoom.us/docs/team-chat-apps/send-edit-and-delete-messages/) ---

Hi @elisa.zoom, I mean sending message in the chat bot chat room. The solutions you provided still didn’t answer my questions. ---

Hi @elisa.zoom , the problem is occurred in Feature → Zoom Client Feature → Team Chat Subscription → Bot endpoint URL[development]. That URL has been publicly accessible but need authentication. Your developer portal didn’t provide custom fields for this situation. May I know how to deal with it?
