# Overview

When it comes to building web applications with Alphi you will need an authentication/ membership service to:

* Identify the user executing the flow
* Limit feature access based on the users plan/ subscription
* Allow users to create, read, update and delete records associated with their account

Utilising our authentication integrations, you can connect popular nocode membership services like Outseta and Memberstack in minutes.

## Including a token in a request to Alphi

When running a flow with authentication enabled, you must include the authorisation token in the request.

```
-H "Authorization: Bearer eyJhbGci..."
```

### Javascript Example

```javascript
fetch('https://live.api-server.io/run/v1/YOUR_FLOW_ID', {
    headers: {
      'Authorization': 'Bearer ' + Outseta.getAccessToken()
      // 'Authorization': 'Bearer ' + $memberstackDom.getMemberCookie()
    }
  )
  .then((response) => response.json())
  .then((data) => console.log(data));
```

{% content-ref url="/pages/h7d9OWiHoVZido9eHV1I" %}
[Outseta](/authentication/outseta.md)
{% endcontent-ref %}

{% content-ref url="/pages/SloSqKCWkPf8dMD8EylZ" %}
[Memberstack](/authentication/memberstack.md)
{% endcontent-ref %}
