Hey Paul, yes, you can use the SCIM API to hook into your IDM platform. We are IDM nuetral, but like these two open source projects:
[Evolvium Midpoint](https://www.evolveum.com/midpoint/)
[Apache Syncope](http://syncope.apache.org/)
Please feel free to close this ticket or let us know if you have additional questions.
Thanks,
Will
