Hello bubblers  
I have been trying to set up a post request with dynamic values within the body from this api url

> **[Data-uri-to-img-url](http://aminariana.github.io/data-uri-to-img-url/)**
>
> This service takes a Base64 encoded DataURI via a POST request, and responds with a URL representing the decoded image.

but whatever combination of try returns the value field empty

Few issues:

1. see screenshot for the proper formatting of the JSON, the “\< \>” don’t go in the key, they go in the value. For instance:  
{  
“key” : “”  
}  
and don’t forget the quotation marks before and after 🙂

2. I don’t think your Heroku app is deployed live, which could be an issue if you’re trying to post to it. I got a 404 when trying to test.

Is there anyway to use the dynamic variables for inserting the subdomain of the POST URL?
