Continuing the discussion from Managing Parameter Storage - SailPoint Identity Services:
I noticed in the Parameter Storage documentation that there is no mention as to WHAT the Token URL should be when setting up Parameter Storage. I understand that the Token URL could be ANYTHING as it is dependent on the SAAS product you are trying to make a call to, but I had hoped there would be SOMETHING there in regards to SailPoint ISC since it went through the effort of writing this doc in the first place. 
Some of you are super geniuses and either already knew what this meant or figured it out on your own, but for those of us with lesser brains, here is what the Token URL format should be like when setting up a Token URL for Identity Security Cloud:

Hopefully this note helps someone in the future.
