# Forbidden

> Error

## What Happened

The requested resource exists and the API key is valid, but the API key does not have permission to access it.

<Tip>The response includes a `detail` property with more information about this error.</Tip>

## How to Fix

* If you are using multiple accounts, ensure the API key corresponds to the correct account where the resource is located.
* Verify you are not using a test API key to access a resource that belongs to a different account. For test/live mode mismatches, see [Test/Live Mode Error](/docs/v1/errors/mode-error).
