Handle 997 and 999 acknowledgements

Understand 997 functional and 999 implementation acknowledgements — webhook delivery, status lifecycle, and remediation.

997 vs 999

A 997 confirms syntactic acceptance at the functional group level. A 999 reports richer implementation status — treat them as separate lifecycle checkpoints.

Webhook delivery

Subscribe to document.partner_ack for asynchronous delivery. Payloads include accepted, rejected, or pending states with segment context translated to plain-language hints.

  • Self-healing engine surfaces repeatable mapping fixes
  • Never reuse ISA/GS control numbers after a hard reject

Retry and exception handling

On reject, update partner mappings or payload fields, then resubmit with fresh control numbers. Keep sandbox and production partners isolated.
