//build URI to add watermark text
            string strURI = "http://api.saaspose.com/v1.0/words/input.docx/insertWatermarkText";
            string signedURI = Sign(strURI);
            //serialize the JSON request content
            WatermarkText watermark = new WatermarkText();
            watermark.Text = "Watermark Text Here";
            watermark.RotationAngle = 45.0;
            string strJSON = JsonConvert.SerializeObject(watermark);
            Stream responseStream = ProcessCommand(signedURI, "POST", strJSON);
            StreamReader reader = new StreamReader(responseStream);
            string strResponse = reader.ReadToEnd();
            //Parse the json string to JObject
            JObject pJSON = JObject.Parse(strResponse);
            BaseResponse baseResponse = JsonConvert.DeserializeObject<BaseResponse>(pJSON.ToString());
            if (baseResponse.Code == "200" && baseResponse.Status == "OK")
		Console.WriteLine("Watermark text has been added successfully");

	    //Here is the WatermarkText class    	    
            public class WatermarkText
            {
                public string Text { get; set; }
                public double RotationAngle { get; set; }
            }


            //Here is the BaseResponse class    	    
	    public class BaseResponse
            {
        	public BaseResponse() { }
	        public string Code { get; set; }
        	public string Status { get; set; }
    	    }
This technical tip allows developers to add watermark text to a Word document using Saaspose.Words REST API in your .NET applications. Some important steps for performing this task are to build URI to add watermark text and then serialize the JSON request content. After that, parse the json string to JObject. Developers can use the WatermarkText class and BaseResponse class for adding Watermark text.
