# Create your first embedded WebEx app
First, create an account in the [Aurinko portal](https://app.aurinko.io/).
Create your app, check 'End user sessions' and 'Messaging' feature for your new app. Besides 'User sessions' your app may need to access CRM or Mailbox APIs.
\
\
Next, log into your WebEx developer account (). If you don't have an account yet request a sandbox, then log in with the sandbox credentials, you will need a sandbox to run your new app in:
Create a new embedded app:
Select both modes: Meeting and Messaging. Then fill out all required fields.
Then specify a valid domain 'example.aurinko.io', start page url '', and space start page url ''. Now you can create your app.
On the next page submit your new app for admin approval, so that you could test it in your own organization.
Go to your sandbox admin site () and approve your new embedded app:
Now you can open your WebEx desktop app and run your app in a room/space
Or when you're in a meeting
