# Bulk Delete by Filters

> Delete all employees matching filter criteria

# Bulk Delete by Filters

Delete all employees that match the given filter criteria. Uses the same filters as the list endpoint. Requires a `filter_hash` for optimistic concurrency — the hash must match what the server computes for the same filters, ensuring the user deletes exactly what they saw.

  import requests
  import os

  response = requests.post(
      "https://api.dcycle.io/v2/employees/bulk-delete-by-filters",
      headers={
          "x-api-key": os.getenv("DCYCLE_API_KEY"),

  result = response.json()
  print(f"Deleted {result['success']}/{result['total']} employees from file")
  ```

  ```javascript JavaScript theme={"theme":{"light":"github-light","dark":"github-dark"}}
  const axios = require('axios');

  const { data } = await axios.post(
    'https://api.dcycle.io/v2/employees/bulk-delete-by-filters',
    { filter_hash: 'abc123def456' },
    {
      headers: {
        'x-api-key': process.env.DCYCLE_API_KEY,
        'x-organization-id': process.env.DCYCLE_ORG_ID,
        'Content-Type': 'application/json',
      },
      params: { 'file_id[]': 'file-uuid-1' },
    }
  );

  console.log(`Deleted ${data.success}/${data.total} employees from file`);
  ```

### Successful Response

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "total": 85,
  "success": 85,
  "failed": 0,
  "errors": []

## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Invalid API key for organization", "code": "INVALID_API_KEY"}
```

### 403 Forbidden

**Cause:** The authenticated user is not a member of the organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Logged User is not Member of Organization", "code": "LOGGED_USER_NOT_MEMBER"}
```

### 409 Conflict

**Cause:** The `filter_hash` doesn't match the current filter state — data changed since the list was loaded

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Filter hash mismatch. The filters have changed since the list was loaded. Please refresh and try again."
}
```

### 422 Unprocessable Entity

**Cause:** No filter parameters provided (safety check to prevent accidental mass deletion)

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "At least one filter parameter is required for bulk delete by filters."
}
```
