To test simply configure the dataResource name in the manifest and then its endpoint in the URL meta parameter that goes in the create request. The manifest would look like:

{
  // ...rest of manifest configuration
  "remoteDataSources": [
      {
          "name": "allUsers",
          "url": "${meta_pluginSettingsUserInformation}",
          "fetchMode": "onMeetingCreate",
          "permissions": ["moderator", "viewer"]
      }
  ]
}

Then when creating the meeting send the following parameters along, adjusting to your needs and resources:

meta_pluginSettingsUserInformation=https://<your-external-source-with-your-authentication>/api/users
pluginsManifests=[{"url": "http://<domain-of-your-manifest>/your-plugin/manifest.json"}]
