# Authentication

Authentication is performed with every API call by sending a header with your unique Brandfolder API key.

- Find your API key at https://brandfolder.com/profile#integrations.
- Click the icon to the right of your key to copy it to your clipboard.
- Use the key in your code when making requests to our API.


The required header in each request is:

`Authorization: Bearer {BF_API_KEY}`

Each response to your API calls will only include the resources that you (or the User whose API key your application is using) can access based on your permissions.
