Separate the lifecycle steps
A typical transaction path may include entry, review, submit or post, completion, receipt, and final UI status. The exact names vary by platform, but the support question stays the same: which step failed first?
If the post request failed, the ticket should lead with posting. If post and completion succeeded but receipt failed, the ticket should lead with finalization or receipt handling. If a search request failed before any transaction post, the ticket should not describe a posting failure.
First failure beats nearby success
Nearby successful calls are useful context, but they should not override the selected failed request. A PM summary should say what failed first, then mention later success as recovery context.
This is especially important when the HAR contains multiple workflows in the same time window. Search, login, account lookup, and transaction posting can sit close together in the network timeline.
Write the handoff in two layers
The PM layer should explain the likely part of the workflow: customer search, account lookup, posting, completion, receipt, or session recovery. The engineering layer should include endpoint shape, HTTP status, failure signal, and correlation ID.
This keeps the ticket readable without hiding the technical signal that Engineering needs.
