VPC connections are required only for FIX API access. REST and gRPC APIs use the public endpoints listed above and do not require VPC setup.
For secure, private connectivity from your AWS VPC for the FIX API, use AWS PrivateLink. This routes traffic over AWS’s private network instead of the public internet.

The PrivateLink connection is used exclusively for FIX API access. The load balancer terminates TLS on port 443.
