Hi Guirgis,
This could be caused by variables not being properly defined in an application resulting in undefined. Possible that they are defined in the 3rd party app and not
the Composer app or vice-versa.
Composer Help
http://docs.genesys.com/index.php?title=Documentation:Composer:Help:Welcome:8.1.4&action=pdfbookPage 49:
Web Service
Invokes Web Services. GET, POST and SOAP over HTTPS are supported.
Calling a Web services application. So if your third party is a WSDL you can configure the third party app that Composer app connects to (if I'm understanding you
correctly) to send a Notification via SOAP. So submit is not valid the information would have to be sent in a SOAP message or retrieved via GET.
Web Request
Invoke any supported HTTP web request or REST-style web Service.
In Web Request the Request Methods are GET, POST, PUT and Delete. Essentially you are requesting information not receiving a submit.
If further investigation is required beyond the Server-Side Web Service/Requets blocks discussion I would recommend opening a Support Case. We are unable to
provide a conclusive response without additional details and clarification.
Based on a very limited understanding of your goals and without having visiblity into your application(s) I don't believe using a submit tag is a valid flow.
I hope this provided additional insight and guidance.
Thank you,
