Using the API gateway pattern, PingAuthorize processes JSON
requests and responses in two distinct phases according to a defined sequence.
The gateway handles proxied requests in the following phases:
Inbound phase – When a client submits an API request to PingAuthorize Server, the gateway forms a policy request
based on the API request and submits it to the policy decision point (PDP) for
evaluation. If the policy result allows it, PingAuthorize Server forwards the inbound request to the API server.
Outbound phase – After PingAuthorize Server
receives the upstream API server's response, the gateway again forms a policy request,
this time based on the API server response, and submits it to the PDP. If the policy
result is positive, PingAuthorize Server forwards
the outbound response to the client.
The API gateway supports only JSON requests and
