Timeout-Retry Sequence

API latency is < 1s in available regions (excluding any network dependency)

We suggest setting:

  • Timeout = 2.5s

This will happen rarely and will be a good indication of a fault.

Offline mode

If the API fails/timeout more than twice in a 15min period, enter “Offline Mode” until reboot.

  1. Cease API calls.
  2. Report error – on screen without preventing usage and/or notify staff.
  3. Default to lookup menu for usage.
