Clearbit API 429 hit during form enrichment surge website leads missing company data

TL;DR

Fix this in Clearbit by acting on the exact message first: queue form enrichments instead of calling synchronously at submit time, retry with backoff, cache results by company domain, and let the form submit succeed while enrichment completes after the surge. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one record, then rerun the full scope and reconcile the counts.

Use this when

• The operation in Clearbit fails with this exact message: Clearbit API returned 429 during a form enrichment surge, website leads were missing company data.
• The same failure repeats on retry with unchanged inputs.
• A run, import, export or alert is blocked until this item completes.

Not for this skill when

• The message is a permission or platform outage notice. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Clearbit, and copy the full message plus the record, account or list involved into the run notes. Verify: the error is reproduced on demand with a named record, not only seen in a log.
2. Apply the specific fix for this error: queue form enrichments instead of calling synchronously at submit time, retry with backoff, cache results by company domain, and let the form submit succeed while enrichment completes after the surge. Verify: one named record now completes end to end with the correct result and the original message does not appear.
3. Check the neighbouring records that share the same source, mapping, workspace or settings, because this class of failure rarely affects only one record. Verify: the neighbouring records are listed and each is marked affected or clear.
4. Compare the result counts, fields or alerts against the source in Clearbit so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Clearbit on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the record so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

A launch surge multiplied form calls past the limit, and because enrichment sat in the submit path, the failures landed on the leads themselves.

The verbatim form searchers paste from the terminal or console. Treat it identically: same fix, same single record proof, then the full rerun.

How to fix this failure in Clearbit

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

Troubleshooting this failure in Clearbit

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

Compatibility: Clearbit at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.
