# SmartRecruiters 422 "candidate email already exists" on the agent's bulk import

## TL;DR

The bulk import creates candidates that already exist, and SmartRecruiters 422s the duplicates. Check by email before creating, and treat 'already exists' as 'update the existing record'. Bulk imports are mostly updates wearing an import costume.

```text
422 Unprocessable Entity: "candidate email already exists" (SmartRecruiters bulk import)
```

## Steps

1. Pre-check the import list against existing candidates by email.
   Expected: The duplicates are identified up front.

2. Split the batch: creates for the new, updates for the existing.
   Expected: Each record gets the right verb.

3. Handle the 422 as a backstop: on 'already exists', fetch and update instead of failing.
   Expected: Races and misses are absorbed.

4. Normalize emails before comparing (case, whitespace, plus-addressing).
   Expected: The dedup actually dedupes.

5. Log the create/update split per import for visibility.
   Expected: The import's behavior is observable.

## When to use

- SmartRecruiters bulk imports 422 on existing emails
- the import is create-only
- re-imports are common

## When not to use

- the emails are genuinely new (check normalization first)
- the 422 is for a different field (read the message)
- duplicates should be rejected (then the 422 is correct behavior)

## Tool compatibility

- SmartRecruiters API
- bulk import workflows

## Variant phrasings

- "smartrecruiters 422 candidate email exists"
- "smartrecruiters bulk import duplicate"
- "candidate email already exists smartrecruiters"

## Why it happens

Bulk imports usually re-run over overlapping data URIs the same sourcing list, the monthly refresh. Without a pre-check, every re-import 422s on the candidates it already created. The import needs to be an upsert in spirit: new records create, existing records update.

## Edge cases

- email normalization decides the dedup's accuracy; get it right once
- the update path needs a field-merge policy; blind overwrites destroy data
- the 422 backstop still races; serialize per email for the paranoid
