Automation QA: Logs, Retries, and Dedupe

Output: A documented QA process covering execution log inspection, retry rule configuration, and deduplication, ready to apply across Make, n8n, or Zapier.

Time required: 45-90 minutes on first setup. 10-15 minutes per workflow thereafter once your checklist is in place.

1. Pull and inspect your execution logs

   Filter the last 7 days of execution history and flag every step showing "error" or "skipped." Each platform has its own path: n8n searches by data value, Make filters by scenario name and error status, Zapier uses Task History.

2. Classify each error by type before applying any fix

   Tag each failed step as one of four types: authentication failure, data format mismatch, rate limit hit, or timeout. Rate limit hits and timeouts are transient (recoverable with retry rules); authentication failures and format mismatches are structural (fix upstream before any retry).

3. Configure retry logic on transient error types only

   In n8n, enable "Retry on fail" with 3 retries and a 30-second wait on any rate-limit or timeout step. In Make, configure the error handler module per error route. In Zapier, retries are automatic and not configurable.

4. Build deduplication rules at the workflow entry point

   Place dedupe logic before any enrichment or write step runs. In Make, use a datastore lookup by email or domain. In n8n, use an IF node against a dedupe list. In Zapier, use a Filter step or Storage by Zapier.

5. Run a pre-launch QA test using a tracer record

   Run the workflow against a single tracer record and confirm every step logs "success." Force a retry failure to verify the delay fires correctly, then submit the same record twice to confirm dedupe blocks the second pass.
