To establish a connection, you first need to create an **ION API file**. The file is generated under **Authorized Apps** tab inside **Infor ION API** component of **Infor IOS**. 

* Click on **+** sign (Add New App) to add a new app to the repository.

* Make sure that the chosen M3 user ID for **Service Account** has proper security roles assigned inside IFS (Infor Federation Services). \
  Make sure that either '**GRID-Administrator**' or '**GRID-RunAsM3User**' is ticked. These enable an authenticated user to start jobs on behalf of other users.&#x20;
