- Send the file config/twillo.properties.xml to the twillo.de administrators support.twillo@tib.eu . If they ask you to change the app-ID, you can do this in the system at Admin -> System -> Configuration by editing the config value OERCAMPUS_TWILLO_APPID.
- Leave the config/twillo-private.key file as it is in the config folder. This file is important for the API to work.
- You need to either have or create a datafield for users which contains the DFN-AAI-ID of a person. Without this ID in the datafield a user cannot upload to twillo.de due to technical restrictions.
- Copy the datafield_id of this datafield (you find this in the DB-table datafields). In Stud.IP go to Admin -> System -> Configuration and edit the config value OERCAMPUS_TWILLO_DFNAAIID_DATAFIELD. What you inserted, should look like 6a9ee3ca3685d2551698a3dc6f0f0eff.
- Once the twillo.de adminstrators received your file and registered your Stud.IP, you can enable the connection to twillo: Go to Admin -> System -> Configuration and edit the config value OERCAMPUS_ENABLE_TWILLO and switch it on.

There you go. From now on all your users with a given DFN-AAI-ID should be able to upload their OERs to twillo.de.
