For basic access that grants access to all content included in the deployment, use an empty payload:

{}

For audience-based content filtering, add:

{
  "https://jorsek.com/content/audiences": [
    "your_audience_name"
  ]
}

Where your_audience_name is the value attribute in the data element referencing a DITAVAL file in the main sitemap associated with your deployment. For example, if your sitemap contains:

<data href="../filters/private.ditaval" name="content-api-audience" value="private"/>

Use:

{
  "https://jorsek.com/content/audiences": [
    "private"
  ]
}
