What information do I need to setup a Web Service add-in that can be invoked through a button press?

[gravanoc]

Hi. I'm pretty comfortable using VBA, but still learning certain concepts. I've been asked to setup an add-in that will invoke the Workday ERP web service. I'm familiar with setting up add-ins, and after reading a bit about web services, I'm pretty sure I can write the code to make the connection. I've also learned about SOAP from w3Schools, and know about HTTP headers and that stuff. Before I dive too deep into this, though, I need to know if I require user access to the actual service to be able to test and confirm that my code works. Do I?

Summary:
1) Create add-in to call web service of Workday (cloud ERP system)
2) Login/Validate credential (Button in excel)
3) Upload (button) to Workday
Here is the web service detail Import_Accounting_Journal Operation Details
