Twitter Filter Rules

Twitter Filter Rules can be created using JSON sent as an HTTP POST to the Twitter REST API Version 2.

The Languages property in GetTwitter can be applied to a Filter Rule using the lang operator in a Filter value definition.

{
  "add": [
    {
      "value": "Apache lang:en",
      "tag": "English Language Filter"
    }
  ]
}

The Terms to Filter On property in GetTwitter can be applied to a Filter Rule using the Filter value definition with optional Boolean operators.

{
  "add": [
    {
      "value": "Apache AND NiFi",
      "tag": "Boolean Terms Filter"
    }
  ]
}

{
  "add": [
    {
      "value": "from:1625695877326340102",
      "tag": "Twitter User ID Filter"
    }
  ]
}
