Volt Authentication API is one of 12 APIs that [Volt](https://apis.io/providers/volt-io/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication. The published artifact set on APIs.io includes API documentation and an API reference.

The Authentication API issues OAuth2 access tokens for the Volt gateway. A POST to /oauth exchanges client_id, client_secret and username/password (resource-owner password grant) for a Bearer access_token used on all other API calls.
