Hello @duncan Team checked all three.

- All three calls ended in under 2 seconds with an empty transcript (caller hung up before any conversation happened).
- On Retell’s side the post-call analysis for each call returned an empty custom\_analysis\_data object IsAppointmentBooked was not set to 1 by us on any of these calls.

So the “appointment booked” value your system is seeing isn’t coming from Retell’s analysis output on these calls. Two things worth checking on your side:

1. In your webhook/API consumer, confirm how you treat a missing/empty IsAppointmentBooked field. If absent values default to 1 or truthy, that would explain the false positives on zero-length calls.
2. The variable name in the agent’s post-call analysis config is literally "IsAppointmentBooked " (with a trailing space). If your parser looks up “IsAppointmentBooked” (no space), the lookup misses and could hit a default. Recommend removing the trailing space in the agent config.

If you can share the exact webhook body / API response you’re receiving for one of these call IDs where you see the false positive, we can pinpoint where the “1” is being introduced.

Thank You
