I want to send messages to Zoom chat (user and groups) from the backend windows service within a company’s Zoom setup. Is it possible with a JWT authentication token? Or if we need oAuth then does the app need its own Zoom account and/or redirect URL to generate the token? ---

Hi @suleman.khalid, Our Chat endpoints require OAuth. This means you will need to create an OAuth app under the account you wish to handle the Chat messages under, and you will need to provide a valid redirect url as part of our OAuth requirements: > **[OAuth - Build an App - Documentation](https://marketplace.zoom.us/docs/guides/build/oauth-app)** > > Create an OAuth App > > OAuth 2.0 is the industry-standard authorization protocol that allows applications to obtain requested access to user accounts over... Let me know if this helps to clarify. Thanks, Will ---

Thanks, Will Is there an alternative authentication method for WinForms applications or Windows services to avoid deploying/using redirect web URL? Our application runs as an unattended background service. Can we use the Zoom SDK for this? Regards Suleman ---

Hi @suleman.khalid, Unfortunately our Chat APIs are only accessible via our OAuth authentication method. While it’s a great suggestion to have an alternative for programs like yours, this is not currently supported. Our SDK does not support Zoom Chat Client actions either. If you’re so inclined, I might recommend submitting a feature request for this here as well: #feature-requests Thanks, Will ---

Thanks, Will It would be great to have such a feature, as now more businesses using Zoom may integrate it directly into existing applications. I have created the following feature request. > [@Zoom API Authentication For Unattended Background Windows Service](https://devforum.zoom.us/t/zoom-api-authentication-for-unattended-background-windows-service/48268): > > This is for developer-specific feature requests. For other requests please contact our customer support team. Is your feature request related to a problem? Please describe. I want to integrate Zoom API calls in (.NET) unattended background windows service but currently, Zoom API only provides OAuth to call the “send message” feature. OAuth requires a redirect URL and user interaction. (which is not fully automated authentication) Describe the solution you’d like Please allow all Zoom API cal… Regards Suleman ---
