# Wix Marketplace When submitting your app to the Wix marketplace, you'll need to provide 3 critical URLs if using the custom authentication option: ### 1. External URL The external URL extension allows you display an embedded instance of your installed app inside the Wix dashboard. {% code overflow="wrap" %} ``` https://exmart.pandium.io/v1/wix/dashboard// ``` {% endcode %} Replace `` and `` with your specific values. ### 2. App URL This App URL is used to initiate an integration install from the Wix Dashboard to kick off the Oauth flow: ``` https://exmart.pandium.io/v1/wix/auth// ``` The URL will most likely resemble the above, but simply use this URL for the 'Install' page of this App in your Marketplace. ### 3. Redirect URL When users authorize your app, Wix will redirect them to this URL with a temporary authorization code. **Sandbox** ``` https://api.sandbox.pandium.com/v0/author/callback/oauth2 ``` ``` https://exmart.sandbox.pandium.com/v1/wix/redirect// ``` **Production** ``` https://api.pandium.io/v0/author/callback/oauth2 ``` ``` https://exmart.pandium.io/v1/wix/redirect// ``` ### Need Help?
