+
+PDF Watermark is currently accessible through the REST API only.
+
+# PDF Watermark
+
+A watermark in a document is usually semi-translucent or faded text, a logo, or a pattern placed in the background or foreground of the page for security, authenticity, and branding.
+
+PDF Watermark API is a cloud based solution to apply watermark on specified pages of a PDF document using a source file.
+
+![PDF Watermark](../watermark_overview.png)
+
+## Input Documents : **Required**
+
+Supported format is PDF (application/pdf). Input PDF with version 1.6 and above is supported.
+
+### Input Document
+
+A PDF document to which a watermark will be applied.
+
+### Watermark Document
+
+A PDF document whose first page will be used as a watermark for the input document.
+The output generated will retain the content along with the watermark from the first page.
+
+## Watermark Parameters
+
+### Page ranges (_pageRanges_)
+
+Specifies the number of pages on which the watermark will be applied. Page numbers are indexed from 1 to N.
+The page ranges are specified as an array of objects whose length cannot exceed beyond 20. Each object has the following properties:
+* **Start Page**  (*start*) : The first page number of the range. Default value is 1.
+* **End Page**  (*end*) : The last page number of the range. Default value is the last page of the document.
+:
+### Appearance (_appearance_)
+
+* **Foreground**  (*appearOnForeground*) : Specifies the placement of the watermark on the page. It can appear in the foreground or background. The default value is true, placing the watermark in the foreground.
+* **Opacity**  (*opacity*) : Specifies the opacity of the watermark, represented as an integer percentage value ranging from 0 to 100. The default value is 100.
+
+## REST API
+
+See our public API Reference for [PDF Watermark API](../../../apis/#tag/PDF-Watermark).
+
+## Apply Watermark on specified pages
+
+The sample below performs watermark operation applying watermark in foreground on specified pages of a given PDF.
+
