ATS webhook stopped firing intake empty

Not specified by the original author.

TL;DR: Monitor the webhook pipeline itself and keep a polling fallback. Alert when expected application events stop arriving, and reconcile the intake queue against the ATS daily. The queue sat empty for two days because the agent treated "no events" as "no applicants" and nothing watched the pipe.

ATS webhook for new applications stopped firing for 2 days  -  the agent's intake queue sat empty and nobody noticed

1. Check webhook delivery status in the ATS and your endpoint logs. Expected: deliveries failing, the subscription paused or expired, or the endpoint returning errors.

2. Fix the endpoint or re-subscribe, then backfill by querying the ATS for applications created during the gap. Expected: the missed applications land in the intake queue with their original timestamps.

3. Add a heartbeat alert: if no application events arrive within N hours on a business day, page the team. Expected: the alert fires during a simulated outage.

4. Add a daily reconciliation comparing the ATS application count against the intake queue count for the same window. Expected: the two counts match on a healthy day; a gap names the missing applications.

5. Write a short runbook for webhook outages: how to detect, how to backfill, who owns it. Expected: the next gap is a known procedure, not a discovery.

Use this when

• Application or event flow stops with no error surfacing in the agent.
• Intake depends entirely on webhooks with no fallback.
• Webhook subscriptions can silently pause or expire.

Not for this skill when

• Events arrive but the agent drops them (that is a processing bug, not a delivery outage).
• The ATS genuinely had no new applications (the heartbeat should account for real quiet periods).
• The queue is empty because a downstream worker is stuck, not because intake stopped.

Variant phrasings

• new application webhooks stopped and nobody noticed
• intake queue empty while applications piled up
• webhook subscription silently died
• agent missed two days of applicants

Why it happens

Webhooks are best-effort delivery over infrastructure nobody owns end to end: subscriptions expire, endpoints break on deploy, secrets rotate and signature checks start failing. The agent monitored the work the events carried but never the pipe itself, so a quiet pipe looked identical to a quiet hiring market. Absence of events is not evidence of absence of applicants.

Edge cases

• ATS maintenance windows: expect planned quiet periods and exclude them from the alert, or the heartbeat cries wolf.
• Secret rotation breaking signature verification: the endpoint returns errors and the ATS backs off. Rotate secrets with a dual-accept window.
• Endpoint deploy downtime: even minutes of downtime can lose events if the ATS does not retry long enough. The daily reconciliation catches what retries miss.
• Real quiet periods (holidays, weekends): tune the heartbeat threshold to business hours or it pages on Christmas.

TL;DR

Fix this in interview scheduling webhook by acting on the exact problem first: open the webhook delivery log for the booking confirmation, find the confirmed booking event that never reached the ATS, check the stage mapping for the confirmed state in the receiving workflow, correct the mapping, replay the missed event, and confirm the candidate stage in the ATS now advances to the booked stage. Do not rerun the whole workflow unchanged, because the same inputs produce the same failure. Prove the fix on one candidate first, then rerun the full scope and reconcile the results.

interview scheduling webhook error booking confirmed but ATS stage not updated

Use this when

• The operation in interview scheduling webhook fails with this exact problem: interview scheduling webhook error booking confirmed but ATS stage not updated.
• The same failure repeats on retry with unchanged inputs.
• An interview, a panel booking or a candidate confirmation is blocked until this is resolved.

Not for this skill when

• The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
• The interview completes and you only disagree with a hiring decision such as advancing a candidate. That is a hiring call, not this failure.

Steps

1. Reproduce the failure on one named candidate in interview scheduling webhook and record the full problem text plus the candidate, requisition or panel involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: open the webhook delivery log for the booking confirmation, find the confirmed booking event that never reached the ATS, check the stage mapping for the confirmed state in the receiving workflow, correct the mapping, replay the missed event, and confirm the candidate stage in the ATS now advances to the booked stage. Verify: the single failing candidate now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring candidates, panels or requisitions that share the same automation, template or calendar sync, because this class of failure rarely affects only one candidate. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in interview scheduling webhook on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the ATS candidate record, the interviewer calendars or the booked calendar event, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the candidate record so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

How to fix - interview scheduling webhook error booking confirmed but ATS stage not updated

The how to phrasing for the same failure in interview scheduling webhook. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

interview scheduling webhook troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

The booking and the stage advance live in different systems joined only by the webhook, so a delivery that fails or a stage value with no mapping leaves a confirmed booking beside an unmoved candidate record until the event is replayed.

Edge cases

• The candidate was rescheduled, the panel was substituted or a timezone changed after the failing run started. Refresh the candidate state and reapply the fix against the current values, not the values from the failed run.
• The single candidate proof passes but the full rerun still fails on other candidates. Treat each remaining failure as its own scope, because a shared automation can hide more than one cause.
• The source systems disagree on the correct value. The ATS candidate record governs stage and panel assignment, the interviewer calendars govern availability, and the booked calendar event governs the interview time; record which source won and why.

Compatibility: interview scheduling webhook at current versions, plus the ATS, calendar or video platform the query names; no extra tooling beyond access to the source records needed to verify results.

interview scheduling webhook troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

Receivers that answer booking events with errors train the sender to retry and eventually drop the event, so the stage gap grows with every booking until the endpoint answers successfully and the backlog is replayed.

Edge cases

• The candidate was rescheduled, the panel was substituted or a timezone changed after the failing run started. Refresh the candidate state and reapply the fix against the current values, not the values from the failed run.
• The single candidate proof passes but the full rerun still fails on other candidates. Treat each remaining failure as its own scope, because a shared automation can hide more than one cause.
