Recommendations

• Set up a local database to store:
  • Received messages and their processing status
  • Settings cache
  • Message status events to be sent to the API
• Event reporting should first save events into the local database and then process the events queue until no unsent messages remain. On error, pause (for example, for 1 minute) and then try again.
• Run the actual messaging as a separate job that takes communication channel bandwidth constraints into account.
