Hello guys, I’d like to ask about [OAuth 2.0 Device Authorization Grant](https://tools.ietf.org/html/draft-ietf-oauth-device-flow-15#page-5), does Zoom OAuth 2.0 Server support it? If don’t, then do you plan to implement it? It is pretty hard to use OAuth 2.0 in embedded devices without this feature. Also has Zoom REST API method to check enabled/disabled SIP connectors feature in a metting/account? Thanks, Alex ---

Hey @olecsys, Have you considered using [JWT Tokens](https://marketplace.zoom.us/docs/guides/auth/jwt) for authentication? > [@olecsys](#): > > Also has Zoom REST API method to check enabled/disabled SIP connectors feature in a metting/account? Here are our SIP phone and device APIs: [https://marketplace.zoom.us/docs/api-reference/zoom-api/sip-phone/](https://marketplace.zoom.us/docs/api-reference/zoom-api/sip-phone/) [https://marketplace.zoom.us/docs/api-reference/zoom-api/devices/](https://marketplace.zoom.us/docs/api-reference/zoom-api/devices/) Thanks, Tommy ---

Hey @tommy, Thank you for your reply. Yes, I considered JWT Tokens, but we’d like to provide user permissions in our Zoom Marketplace App to make its using clear as possible for users. Thanks for links about SIP phones and SIP devices, but we need to check if meeting has a possibility to receive calls from any SIP clients, so it is something like [Cloud Room Connector (CRC) feature](https://support.zoom.us/hc/en-us/articles/201363273-Getting-Started-With-H-323-SIP-Room-Connector) that is enabled only for licensed users if I understand correctly. I’ve found [SIP dial strings docs](https://support.zoom.us/hc/en-us/articles/202405539-H-323-SIP-Room-Connector-Dial-Strings), but I’d like to ensure that our device can/cannot connect to a particular Zoom meeting. Sorry for bothering you. Thanks, Alex ---

Hey @tommy, We have a hardware encoder and we’d like to send/receive media stream to/from a particular meeting via SIP protocol. Also it would be great if you have a REST API methods to interact with a meeting chat(get/send messages). Thanks, Alex ---

Hey @olecsys, Thanks for the info, can you please add OAuth 2.0 Device Authorization Grant as a feature request here: #Feature Requests Currently we only support [OAuth 2.0](https://marketplace.zoom.us/docs/guides/auth/oauth), and [JWT](https://marketplace.zoom.us/docs/guides/auth/jwt). As for “In Meeting Chat” APIs, please see my post here: > [@Zoom meeting chat API](https://devforum.zoom.us/t/zoom-meeting-chat-api/23083/2): > > Hey @Imwebdev, Currently we do not have APIs for [In Meeting Chat.](https://support.zoom.us/hc/en-us/articles/203650445-In-meeting-chat) The [Chat APIs](https://marketplace.zoom.us/docs/api-reference/zoom-api/chat-channels/) we have are for [Zoom Chat](https://zoom.us/feature/messaging).
