Identify the set of GET endpoints you need per vehicle (for example, odometer, fuel level, location, battery charge) to bundle into one batch call
Construct a batch request body listing the desired endpoint paths and send it to the Smartcar batch endpoint with the vehicle's access token
Parse the response array, which returns an individual status code and body for each requested endpoint, handling per-item errors without aborting the whole batch
Implement retry logic only for the failed sub-requests rather than re-issuing the entire batch to avoid redundant data pulls
Cache the successful sub-responses with their timestamps to respect rate limits before the next scheduled batch poll
Log per-endpoint latency from batch responses to identify slow OEM data paths and adjust polling cadence accordingly
Known gotchas
A batch request counts against your rate limit for each sub-endpoint included, not as a single call — size batches accordingly
Individual endpoints within a batch can return errors (for example, a vehicle asleep or a permission not granted) while others succeed; always check per-item status codes
Not all endpoints are available in batch mode; verify the current list in the Smartcar API reference before building your request payload
