# Accessing the App

Installed Apps can be found under Data Products -> Apps\
Clicking on the installed Transfer app will bring up a screen that has the launch app button.\
Clicking this button will launch the app in a new browser tab, and prompt for the Snowflake login credentials.

The url from the launch app should be shared with any users that will need to access the application.

The same URL is the base address for the programmatic API (`/api/v1/...`). If the app is reinstalled or the service is recreated, the URL can change. See [Finding the URL](/transfer-app-docs/user-guide/administration/finding-the-url.md).

Typically, customers will create a referring link on a company site that directs to the url captured.\
Note that it is possible that the app url can change if the app is removed and reinstalled, or if database administrators make changes to the app, and need to create a new service for it. Having a referring link that can be updated removes the need to inform users of any changes.

You can also retrieve the app URL from SQL — see [Finding the URL](/transfer-app-docs/user-guide/administration/finding-the-url.md).

### Granting users access to the app

Access is controlled by three application roles: `TRANSFER_APP_ADMIN_ROLE`, `TRANSFER_APP_AUTHOR_ROLE`, and `TRANSFER_APP_USER_ROLE`. Grant the user role to uploaders, the author role to data engineers who configure transfers, and the admin role to administrators.

For the full grant examples and role guidance, see [User Access](/transfer-app-docs/user-guide/administration/user-access.md).
