Generating an http URL for Radio App metadata

[South Coast FM Tech]

Hi Jan,

I'm looking to use various elements of Text Sources to build an https: URL that feeds a streaming Radio App by HTTP POST.

The App feed URL is in the form:
https://radioapp.com/abcd?title=SongTitle&artist=SongArtist&imageUrl=https://mysite.com/ProgramImage.jpg&key=yfgufg

TextSource1 uses an XML file from the Playlist Automation system
TextSource1 %1% is the Artist text
TextSource1 %2% is the Title text

I have Task Scheduler updating the N/A text in two text sources.
Text Source 2 N/A is the Program Name text
Text Source 7 N/A is the Program image filename

The RDS output text cycles through Text Source 1 to Text Source 6.
Text Source 7 is never displayed, but only used to hold the changing Program image filename in the N/A text.

I have created a connection "RadioApp" > Bridge > Internal Channel with Data Distribution something like:
sendhttp url":https://radioapp.com/abcd?title=SongTitle&artist=SongArtist&imageUrl=https://mysite.com/ProgramImage.jpg&key=yfgufg"

Is there a way that I can directly access Text Source 1 %1%, Text Source 1 %2% & Text Source 7 N/A & then use those to build the sendhttp URL?

thanks, Rod.
