## Sideload Extension App for Development or Testing

{% hint style="info" %}
Note that this method does not support obtaining user identity as app authentication is not supported. If you wish to test an app that requires user identity, you will have to create an actual app using the steps above with the assistance of your pod administrator
{% endhint %}

1. Host the extension app on a TLS-enabled server together with the application manifest (`bundle.json` file)
2. Visit `https://my-company-pod.symphony.com/?bundle=https://localhost:4000/bundle.json` assuming your app is running on localhost on port 4000 and you have a bundle.json served on the root
3. Acknowledge the developer mode warning and proceed
