A system includes an interface and a processor. The interface is configured to receive, at an application routing platform, an API call for an application platform comprising a signed tenant token. The processor is configured to determine that the signed tenant token is valid; determine an application platform token for the application platform; associate a root certificate with the application platform token; determine routing information to the application platform based at least in part on the API call; and provide the application platform the API call and the application platform token using the routing information to enable access to the application platform, wherein the application platform determines whether the application platform token is valid using the root certificate and executes the API call in response to a determination that the application platform token is valid.
