# Bulk Delete Contacts

> Delete up to 500 contacts in a single call

## Request

Deletion is permanent for the contact row and its direct properties. Associated activities, notes, and tasks are preserved in the timeline but lose their contact back-reference. To merge rather than delete, use `POST /v1/contacts/merge`.

### Headers

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

<ParamField header="Idempotency-Key" type="string">
  Strongly recommended. The same key returns the original result within 24 hours.
</ParamField>

### Body Parameters

<ParamField body="contact_ids" type="array" required>
  Array of contact UUIDs to delete. Maximum 500.
</ParamField>

<ParamField body="dry_run" type="boolean" default="false">
  When `true`, the API validates input and returns counts but makes no changes.
</ParamField>

## Response

<ResponseField name="data" type="object">
  <Expandable title="properties">
    <ResponseField name="deleted_count" type="integer">Number of contacts successfully deleted</ResponseField>
    <ResponseField name="not_found_count" type="integer">Input IDs that did not exist in this workspace</ResponseField>
    <ResponseField name="errors" type="array">Array of `{ contact_id, code, message }` for rows that failed</ResponseField>
  </Expandable>
</ResponseField>

Responses include `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, and `X-Request-ID`. Each successful deletion emits a `contact.deleted` webhook event.
