Spot the symptoms fast
- Duplicate contacts or companies appearing shortly after an import or form submission.
- The same email or task being sent or created repeatedly, sometimes every few minutes.
- Spiralling tasks or API calls that push your task quotas higher than normal.
Ten 10–15 minute checks (HubSpot, Zapier and simple integrations)
1. Check workflow history in HubSpot for a sample record — note what property change or event time is triggering the workflow.
2. Look for "field-change" triggers (contact property updated): are small writes (timestamps, sync flags) causing retriggers? Add a specific value-change condition where possible.
3. In HubSpot, confirm dedupe settings and primary identifiers (email, company domain). Duplicate creation often starts at import or bad matching.
4. Search for a processed/handled flag or last-processed timestamp on the record. If none exists, add one so a workflow or Zap can set it before ending.
5. Inspect Zapier task history and path filters: are Zaps firing more than once for the same event because filters are too loose? Tighten filter steps to a single clear condition.
6. Check connector retry behaviour (Zapier, middleware, custom API): automatic retries on a 4xx/5xx can replay events — add idempotency by using a reference ID or processed flag.
7. Review overlapping automations: two workflows or a workflow plus a Zap both handling the same event will bounce updates between systems. Identify and disable one owner.
8. Confirm any time‑window or rate-limiting rules: some tasks should only run once per day/per hour — add a last‑run timestamp condition or use a short time window filter.
9. Inspect sources and ownership: unclear source fields (multiple systems writing "source") let integrations fight. Enforce a single source-of-truth rule per field.
10. Run a quick replay test: pause live automations, make one controlled change to a test contact, and watch logs through HubSpot workflow history and Zapier task detail to see the true sequence.
Safe testing and simple prevention steps
When you test, clone the workflow or Zap and use a single test record. Pause or turn off production automations first, then run the cloned flow against your test record while you watch logs; this avoids accidental live emails or repeated tasks.
Prevention is mostly small rules: add a processed flag or last-processed timestamp; use specific change filters ("property changed from X to Y"); assign single ownership for each integration; limit triggers with a short time window; and require a unique identifier for create/update actions. These changes are low-effort and usually stop loops quickly.
If you want a calm pair of hands to run through the checklist with you and tidy the most fragile rules, Optira can help run the checks and put simple fixes in place without overhauling your whole setup.
