# Streaming Schema V2

We are sending multiple vehicle data points in a single message. You may find the full JSON Schema at :

* Root object spec: [json-schema/janus/0002/spec.json](https://raw.githubusercontent.com/highmobility/open-api-specifications/refs/heads/main/json-schema/janus/0002/spec.json)
* Data object spec: [json-schema/auto-api/0002/spec.json](https://raw.githubusercontent.com/highmobility/open-api-specifications/refs/heads/main/json-schema/auto-api/0002/spec.json)

Here is an example of a single message.
