Connect FME and map.apps

The ETL proxy servlet is an additional server component designed to handle various integration scenarios between map.apps and FME Server. This is the most versatile option and should be used in most scenarios. Using the proxy servlet, the map.apps authentication provided by ArcGIS Online/Portal, Keycloak or security.manager EE (deprecated) can be used to secure FME Server requests.

The security.manager EE generic URL protection is a default functionality of security.manager that doesn’t require any additional installations. However, it shouldn’t be used if you want to protect more than one FME Server URL or if you want to upload larger files to FME Server.

Using the map.apps proxy is often the easiest solution. However, it should only be used for apps that are publicly available and do not require any authentication.
