DevicesIdCallbacksNotDelivered extends Request
Retrieve a list of undelivered callbacks and errors for a given device, in reverse chronological order (most recent message first). SNR will be deprecated (see [Newsletter](https://backend.sigfox.com/welcome/news) for details). To monitor radio link quality, please use the [Link Quality Indicator (LQI)](https://support.sigfox.com/docs/link-quality:-general-knowledge) which is more relevant than SNR in Sigfox network.
