## Common causes

- The API key you used isn't correct.
- If the API key worked previously, it may have been revoked.
- The API key you specified is for another environment. For example, you're trying to work with sandbox using a live API key.

## Common solutions

- Check that the API key exists in your Paddle Dashboard.
- Create a new API key, or copy the existing key again from your Paddle Dashboard.
- Check that you're using the correct API key for the environment.
