I believe there was some Apigee incident today. But, this API is still breaking.

Solved! Go to Solution.
We're sorry about that disruption. It was due to an error on our end. We've corrected the problem. At this point GET /v1/organizations
should work now. And it will return the same results as GET /v1/organizations/
.
