PEPPOL Document Validation

See more HTTP Misc Examples

Demonstrates how to call a Web service to validate your PEPPOL documents according to the latest PEPPOL rules. The validation service requires UBL files. Rust

// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// --------------------------------------------------------------------------------
// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.

// We are sending the following POST:

// POST /wsdvs HTTP/1.1
// Host: peppol.helger.com
// Content-Type: application/soap+xml; charset=utf-8
// Content-Length: <length>
// 
// <?xml version="1.0"?>
// <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

// </validateRequestInput>
// </S:Body>
// </S:Envelope>

// Build the SOAP XML shown above.
// First load the PEPPOL invoice that will be the data contained in the <XML>...</XML> SOAP element.
// We are using the XML invoice obtained from https://github.com/austriapro/ebinterface-standards/blob/master/schemas/ebInterface5p0/samples/ebinterface_5p0_sample_ecosio.xml
