Version
Description
PingFederate
* 
The Experience Service supports all subsequent builds within the same minor version (for example, 9.3.x).
9.3.3 (Patch 5) or later
* 
We recommend that you are running PingFederate 11 or later. While the Experience Service will work with PingFederate 9.3.3, we do no recommend it, as PingFederate has discontinued security support for it as of June 2022.
PingFederate acts as the OpenID provider and authorization server for SSO-enabled ThingWorx and Experience Service. PingFederate is installed when ThingWorx is configured for SSO.
Postman
Latest
Postman is used to acquire an OAuth access token from the PingFederate authorization server. This access token is used during the Experience Service installation process.
