 * __`ID_API_CONNECTION_API_URL`__ Optional url to use for OSM API calls aftern the initial authentication is complete when using a custom OAuth2 connection (see above). If unspecified, `ID_API_CONNECTION_URL` will be used for both the authentication and subsequent API calls.
 * __`ID_API_CONNECTION`__ - Either `live` or `dev`, if only either one should be made offered for editing.
 * __`ID_PRESETS_CDN_URL`__ - The URL where iD should fetch it's tagging presets from. Needs to point to a CORS enabled web server which is serving the `package.json` and `dist` folder of a repository built on [`@ideditor/schema-builder`](https://github.com/ideditor/schema-builder).
