Request data

URL request format

1
https://{serviceURL}/getServiceNodeSystemReference?apiKey={Your_API_Key}

serviceURL is your Smart Layer Tile Service endpoint, without /openapi.json.
Your_API_Key is a My.TomTom API key with NDS.Live services enabled.

This method takes no request body.

This method needs no request headers.

On success, the body is a zserio-encoded NdsSystemToken object with one field:

Field	Description
`mapId`	The UUID of the NDS.Live system. All nodes of the same system return the same ID. Services for different products return different IDs: for example, the ADAS and ISA evaluation services.

This isn’t the service node’s own ID. The node ID is in the response of getServiceNodeLegalInfo.

This method doesn’t return an ETag, so it doesn’t support conditional requests.

Besides the codes below, any method can return the common errors, for example 401 for a missing API key.

Code	Meaning
`200`	OK. The response body holds the `NdsSystemToken`.
`404`	Not found.
`410`	Gone. The Smart Layer Tile Service is decommissioned. Ask the NDS.Live Registry for another service.
`500`	Internal server error.
