I`m trying to call a Nav 2013 R2 web service codeunit with a custom SOAP command and I get a response indicating that the parameters being passed are null, which they are not.

Now I've played about a lot with webservices but it's normally me calling them from NAV rather than calling a NAV one. On top of this, I don't really know JavaScript:-) Anyway, I have a simple NAV webservice which adds a record to a table. I am trying to call it as a SOAP web service but don't mind if there's a better option such as OData.

Does anyone have an answer as to why this is happening or could point me in a direction that could help solve this? Thanks!

Here is the SOAP request:

Check namespaces in wsdl definition and your request. Namespaces are case sensitive.

wsdl:

urn:microsoft-dynamics-schemas/codeunit/WebTestCodeunit

reqest:

urn:microsoft-dynamics-schemas/Codeunit/WebTestCodeunit

This could throw the exception you see.
