Add a Watermark to a PDF in Power Automate

In this example, we will add a Watermark to a PDF document in Microsoft Power Automate. Follow the same steps if using Azure Logic Apps.

Our first step in setting up our flow is getting the contents of a PDF file from Azure Blob (this could be retrieved many other possible file sources as well, such as OneDrive, SharePoint, Box, Google Drive, etc.). Then, we will pass the contents of this file into the Cloudmersive PDF connector with the “Add a text watermark to a PDF” action. If you are new to using one of our API Keys in Power Automate or Azure Logic Apps, you will be prompted to insert your API Key and a Connector Name. Once this has been completed, we will pass in the desired watermark text and file name, as well as the font family name, font size, font color, and font transparency for the watermark text. Finally, we will create a new file in your preferred file drive to store the output from this function.

You can see here how our flow should look once you have followed these steps:

Then, we can run it, and below, you will see the result:

Now, you have an easy to use template for adding watermarks to your PDF documents.
