### Setup your subscription and clients

Before you can get started and use the Energy Hub Alliance, you need to setup clients for the API and streaming clients.

<Note>
  Subscriptions, API keys and streaming clients can be created once you have
  access to the [Partner Portal](https://partner.energy-hub.io). To apply for
  access to the partner portal contact us at
  [info@energy-hub-alliance.com](mailto:info@energy-hub-alliance.com).
</Note>

<AccordionGroup>
  <Accordion icon="layer-group" title="Create new subscription">
    To add a new subscription, you need to provide a application name and a
    redirect URL. The redirect URL is needed for the connect flow, to direct the
    user back to your application.
  </Accordion>

  <Accordion icon="key" title="Create first API key">
    To authenticate to the Energy Hub API, you can create one or more API-keys.
    Make sure to store these API-keys safely, since they will be used to
    authenticate your application. The API keys are connected to your
    subscription.
  </Accordion>

  <Accordion icon="signal-stream" title="Create first streaming client">
    To recieve streaming data, create a streaming client in the partner portal
    and configure your Kafka Broker to recieve messages.
