I am trying to integrate SMSGlobal for sending SMS using SOAP but getting 404 error. I have tried using custom template request as well but still not working. Its giving this error: Caused by: org.apache.axiom.om.DeferredParsingException: com.ctc.wstx.exc.WstxParsingException: Illegal processing instruction target ("xml"); xml (case insensitive) is reserved by the specs. any idea how to see actual error or suggestion to resolve it? SMSGLobal SDK: https://www.smsglobal.com/ae/sdks/ REST integration needs custom header so unless I write JavaAction, i don't see any other way to integration.
