GET
Get retry history for a call
Returns the complete retry history for a single call. When a campaign is configured with retry logic, calls that fail or are not answered are automatically redialled after a configured interval. This endpoint returns every dial attempt linked to the parent call, the attempt number, the outcome (
completed, no-answer, busy, failed), the duration, and the timestamp of each attempt, so you can reconstruct exactly what happened before the lead was reached (or finally written off).
When to use this
- Why didn’t we reach this lead?: inspect the retry history to see whether the lead was repeatedly busy, never answered, or only failed on the first attempt.
- Tuning retry policy: if many leads reach the maximum retry count without ever being answered, consider extending the interval or shifting it to a different time of day. See Auto-retry.
- Compliance review: produce a per-call dial log to demonstrate the number of contact attempts made.
- Cost attribution: confirm how many billable minutes a difficult-to-reach lead consumed across attempts.
