ReST integration scheme
Identity Governance and Intelligence includes a ReST (Representational State Transfer) web service layer that can use HTTP to exchange data with an external target system.
The basic common scheme of integration is shown below:

- 1 - A request is sent from the ReST layer of Identity Governance and Intelligence to the ReST interface of the target system.
- 1* - The ReST interface of the target system converts the request to a consistent target system format.
- 2* - The target system returns the requested data to the ReST interface.
- 2 - The ReST interface converts the data provided in step 2* to a consistent Identity Governance and Intelligence format.
