Need help with sharepoint flow to get attchements in mail

Abhijit12641,

Can you provide a little more detail about where the file you want to attach?  You can't attach files to the approval email as it exists today.  To include a URL, you can use the markdown syntax to define the URL easily.  In the start and wait for approval action, in the Detail box, you will add your instructions or whatever and wherever you want and use [text](link URL).  How you get the text and URL can be manually typed or gotten dynamically via get actions or variables, just depending on where the file is.  You can see more info on markdown https://aka.ms/approvaldetails.  Here's an example of an approval with a hyperlink that works.  In the example, the URL is the output of an expression formula to build a URL.
