# POST - Authentication Token

Before you can do anything else with the Sypht API you will need to request a bearer token using your client id and secret available in the [app](https://app.sypht.com/credentials). Please note that bearer tokens are valid for one hour and we strongly advise you to securely cache them to reuse on subsequent API requests.
