XML Namespace Error

TOPIC

If the XML namespace in the SOAP message does not match the namespace expected for the API, the SOAP server may return a "Server did not recognize the value of HTTP Header SOAPAction" or similar error.

DISCUSSION

The XML namespace URI for web services powered by Currency Server is:

• http://webservices.currencysystem.com/currencyserver/ (from version 5)
• http://webservices.cloanto.com/currencyserver/ (before version 5)

This URI does normally not need to be entered manually, as it is generally autoconfigured by the development environment after the web service access point URL is set up.

The Simple Object Access Protocol (SOAP) specification states that "A SOAP application... MUST discard messages that have incorrect namespaces". Accordingly, if the SOAPAction parameter in the HTTP request does not fall under the expected namespace, then an error like "Server did not recognize the value of HTTP Header SOAPAction" may be returned.

If you receive this error, double-check the XML namespace URI to confirm that it matches the web service URI. Note that this URI only defines the XML namespace. It has no relationship with the actual URL used to access the service.
