Attributes are added to a sentence using the POST request to <host>/Congree/api/AuthoringMemory/v1/Sentences/<sentenceID>/Attributes.

<sentenceID> is the ID of the sentence you want to assign an attribute to.

To be able to assign attributes to a sentence they must have been defined (Defining Attributes).

The body of the request contains a JSON object specififying the attribute(s) to be assigned. The attributes are items of an object array. The structure of the JSON object is shown below:

[
  {
    "Name": "string",
    "Values": [
      "string"
    ]
  }
]

Property	Description
Name	The name of the attribute
Values	An array of string values
string	the actual value(s)

Let's assume we want to assign the attribute "ProductGroup" with a value of "Authoring Memory" to a sentence. The body would contain this JSON object:

[
  {
    "Name": "ProductGroup",
    "Values": [
      "Authoring Memory"
    ]
  }
]

A method assigning attributes to a sentence could look like this:

private void AddAttribute(string host, string token, string sentenceId, string body){
	var client = new RestClient(host + "/Congree/api/AuthoringMemory/v1/Sentences/" + sentenceId + "/Attributes");
	client.Timeout = -1;
	var request = new RestRequest(Method.POST);
	request.AddHeader("Authorization", "Bearer " + token);
	request.AddHeader("Content-Type", "application/json");

	request.AddParameter("application/json", body,  ParameterType.RequestBody);
	IRestResponse response = client.Execute(request);
}
