Parallax

Live vehicle data and many remote commands in the Rivian app use Parallax: protobuf payloads keyed by RVM (remote vehicle message) strings, delivered over GraphQL WebSocket or sent via gateway mutations.

Transport

Direction	Endpoint	Mechanism
Subscribe (read)	`wss://api.rivian.com/gql-consumer-subscriptions/graphql`	`ParallaxMessages`
Command status	same WebSocket URL	`vehicleCommandStatePx`
Write / commands	`POST https://rivian.com/api/gql/gateway/graphql`	`sendParallaxPayload`

Every read update looks like { rvm, payload, timestamp } where payload is base64 protobuf.

Feature flags

Flag / feature	Effect
`parallaxVehicleState` + `PX_STATE_ALL`	Adds vehicle-state RVMs to the subscription
`parallaxCommand` + `PVS_*_CMD`	Routes remote commands through `sendParallaxPayload`

Full gating model and flag catalogs: Feature flags.

When flags are off, the app falls back to Legacy APIs (vehicleState, sendVehicleCommand, etc.).
