</span>The bare minimum is the endpoint, if the implementation is broken and doesn't check Audience conditions. That's not per se a security hole unless they also don't check the Recipient attribute, but that takes some dedicated pen-testing to determine. I have done integrations that did not have an entityID and worked like that, though after reporting it I was able to get them to configure one (in their view, the audience to check for).<br>
<br>
When in doubt, stick whatever the user identifier has to be in the NameID and see if it works, assuming you know the endpoint to create the metadata around.<br>
<br>
It is less work to just experiment, which takes a few minutes, than worry about getting all the details right.<br>
