I’m currently working on integrating Zoom Phone Smart Embed into my project. I would like to test this integration using a localhost domain. Is it possible to use localhost for this purpose? If so, could someone guide me on how to set it up correctly?

Hi @ayenal8684 , yes if you have have met [all the pre-reqs](https://developers.zoom.us/docs/zoom-phone/smart-embed-guide/#prerequisites), you should be able to test deploy.

See the video guide as well:

Hi.

I’m also trying to develop using Zoom Phone Smart Embed. Were you able to resolve this issue? I added `https://localhost` to the allowed domains and configured my dev server to use HTTPS, but I still can’t sign in.

Hi @user170  
Thanks for reaching out to us… You won’t be able to run the Zoom Smart Embed on your localhost, please make sure to use an HTTPS domain to serve your application
