# Import Companies

> Bulk-import companies from a JSON array or CSV payload

## Request

Supply either a `rows` array or a raw `csv` string. Imports up to 500 rows are synchronous; larger payloads are queued and tracked via `job_id`.

### Headers

```
Authorization: Bearer wbk_your_api_key_here
Content-Type: application/json
```

<ParamField header="Idempotency-Key" type="string">
  Strongly recommended. Returns the original result (including `job_id`) within 24 hours when replayed.
</ParamField>

### Body Parameters

<ParamField body="rows" type="array">
  Array of company objects with the same fields accepted by `POST /v1/companies`.
</ParamField>

<ParamField body="csv" type="string">
  Raw CSV string. Provide either `rows` or `csv`.
</ParamField>

<ParamField body="has_header" type="boolean" default="true">
  Applies only to CSV imports.
</ParamField>

<ParamField body="mapping" type="object">
  CSV-only. Maps CSV header names to company fields (e.g. `{ "Company": "name", "Website": "domain" }`).
</ParamField>

<ParamField body="update_existing" type="boolean" default="false">
  When `true`, rows with matching `domain` are updated; when `false`, they are skipped.
</ParamField>

<ParamField body="tags" type="array">
  Optional array of tag strings applied to every imported company.
