Transaction Categories Type

You can specify whether you want the transactions returned in a connection to be categorised as personal or business categories. This is done below in the following:

{
  "id_token": {
    "sub": {
      "essential": true
    },
    "mh:cat_type": {
      "essential": true,
      "value": "business"
    }
  }
}
