What are you suggesting? 

I have posted in my previous email the script that works.  However,…
- assuming that I would like to keep in script this line:

        resp = requests.post(url=URL,data=request, auth=(USERNAME,PASSORD))

How do I trap the "data stuff" in Omnis?  
Let's assume that "request" is simply XML formatted string.

What would be the purpose of "auth=(USERNAME,PASSORD)" since I only want to run method in the library?  
(there is no database connection needed, just run test method in the instantiated object class)

Can you elaborate on this?
I am sure this may be helpful for not just for me.

Thanks,
Greg
