Answer
Webservice endpoint not working
Best answer by ruchikasharma23
In 23R2, Support Contract Versions 2 and 3, which supported the SOAP API, have been removed.
The removal of these contract versions affects endpoints as follows:
• System endpoints with Contract Versions 2 and 3, which are Default/17.200.001 and Default/18.200.001, respectively, do not work.
• Custom endpoints with Contract Version 2 and 3 are no longer supported.
