I am searching solution related to email filed in workflow recipe integration

I am using Email field in workflow block to create recipe and integrate in a boad.
I got success to perform these activities but when I am trying to get the email template on by nodejs (backend) code it is giving me email template as raw instead it should fill the values and send it to the node js as I have selected which filed should come on which place while installing the recipe.
Please help me to resolve this issue.
