# Forbidden

Returned as `application/problem+json` with `code` `forbidden` and HTTP status `403`.

The request is authenticated, but this key is not allowed to perform the action.

## Common causes

* The key lacks the permission required for this action.

## How to resolve

* Use a key for the account that is allowed to perform the action.
* If you believe you should have access, contact support with the `request_id`.

## Example

```json
{
  "type": "https://docs.usglobalmail.com/api/problems/forbidden",
  "title": "You are not permitted to perform this action.",
  "status": 403,
  "code": "forbidden",
  "request_id": "req_8f3c2a1b9d",
  "instance": "/v1/mails"
}
```

> Retrying without changing the request will not help — fix the request first.
