Response Codes

All API requests will respond with an appropriate HTTP status code.

Your API client should handle each response class differently:

  • 2XX codes are successful responses.
  • 4XX codes are client error responses, meaning there was an error with the way the request was submitted, such as a missing parameter or invalid value. You should modify requests before retrying.
  • 5XX codes are server error responses. There may be a temporary issue on the Samsara side, so you may want to retry after some delay. Please use exponential backoff as a retry model - see here for an example algorithm.

Error Codes

Here is a table of error codes that may help you debug. The error response body may include an error message, but do not hard-code against this message. We reserve the right to change the error message without auto-incrementing the API version. Only use error messages for debugging purposes.

Status CodeDescription
400Bad Request - General client error, possibly malformed data.
401Unauthenticated - The API key is missing or invalid.
404Not Found - The API endpoint is invalid or a path parameter is missing or invalid (e.g. id in /fleet/drivers/{id})).
405Method Not Allowed - The API endpoint does not accept that HTTP method.
429Too Many Requests - The client has reached or exceeded a rate limit, or the server is overloaded. See Rate Limits for suggestions on retry patterns.
5XXInternal Server errors - something went wrong with Samsara's servers. These responses are likely momentary errors (e.g., temporary unavailability), and as a result, requests should be retried using exponential backoff. Note that the body of these responses will be strings and not JSON encoded.


The API has a global timeout of 90 seconds.
