What usually breaks in USPS integrations
Real failure modes APIWORX sees in production and how the managed service handles them.
Webhook drops during peak traffic
Source platforms drop a small but non-zero share of webhooks under load. APIWORX backs every event stream with reconciliation polling so nothing is silently lost.
Schema changes break field mappings
Vendors ship API changes without notice. APIWORX monitors for shape drift and updates mappings before downstream systems break.
Auth token expiry during off-hours
OAuth refresh failures usually surface as silent sync stalls. APIWORX alerts on token expiry and re-auths automatically wherever possible.
