## New Workers bulk secrets API endpoint

[Workers](https://developers.cloudflare.com/workers/)

Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/changelog/post/2026-06-03-bulk-secrets-api/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

You can now create, update, or delete multiple secrets for your Worker in a single request using the [bulk secrets endpoint](https://developers.cloudflare.com/api/resources/workers/subresources/scripts/subresources/secrets/methods/bulk_update/).

- Include a secret with a value to create or update.
- Set a secret to `null` to delete.
- Secrets not included in the request are left unchanged.

The following example creates `API_KEY`, updates the already existing `DB_PASSWORD`, and deletes `OLD_SECRET`:

```json
{
  "secrets": {
    "API_KEY": { "type": "secret_text", "name": "API_KEY", "text": "my-api-key" },
    "DB_PASSWORD": { "type": "secret_text", "name": "DB_PASSWORD", "text": "my-db-password" },
    "OLD_SECRET": null
  }
}
```

You can do the same from the command line using [`wrangler secret bulk`](https://developers.cloudflare.com/workers/wrangler/commands/workers/#secret-bulk):

```sh
npx wrangler secret bulk < secrets.json
```

To delete a key, set its value to `null` in the JSON file. Deletion is not supported with `.env` files.

Each request supports up to **100 total operations** (creates, updates, and deletes combined).
