404 Not Found

404 Not Found is returned in two cases:

No load with the given ID exists for your tenant.
A load record exists but has no associated trips (abandoned creation). These loads are treated as non-existent by the API.

On the right side, you can see examples of different error codes by clicking Example and selecting the response code.

Rate Limits

All endpoints are subject to rate limits to protect the API from traffic spikes. For detailed information, see the Rate Limits section.
