How can I send document data to a web service from a nintex

[#1]

Hi,
I have a SharePoint Nintex 2010 workflow activity on a item in a document library that send a metadata and document data to a web service. The metadata is going through correctly, but I am having problem sending the document data/content. Any help will be greatly appreciated

Web method: UploadDocument

Soap editior (content):

<?xml version="1.0" encoding="utf-8"?>

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

    <soap:Body>

        <UploadDocument xmlns="http://WebService/1.0.0

           <request>

                 <Id>{ItemProperty:ID}</Id>

                 <Name>{ItemProperty:FileLeafRef}</Name>

                 <Modified>{ItemProperty:Modified}</Modified>

                <Metadata>

                   <Attribute>

                     <Key>Title</Key>

                     <Value>{ItemProperty:Title}</Value>

                  </Attribute>

                  <Attribute>

                     <Key>Group</Key>

                     <Value>{ItemProperty:Group}</Value>

                  </Attribute>

                   <Attribute>

                     <Key>Document Type</Key>

                     <Value>Other</Value>

                  </Attribute>

                  </Metadata>

                  <Data>[FileData]</Data>

            </request>

        </UploadDocument>

    </soap:Body>

</soap:Envelope>

I am not sure how to include file content between the tags <Data></Data>.

Thanks,

Abraham

Where is the FileData coming from? How is it retrieved? Is this the entire file contents, or just data fields within the file?

[#3]

FileData is the entire content of the file. I need to retrieve the file content and assign it to a variable FileData.

Well from the userguide documentation, To pass the byte array of the document under workflow, type [FileData] into any input field. At runtime Nintex Workflow will base64 encode the file and pass that as the value.

This can be used in Call a Web Service or Web Request actions. Can your webservice take the base64 encoding? This may be were your issue lies.

There is a previous post similar to this, Is it possible to use a Nintex workflow in SharePoint to copy/move an attachment from an item in lis...​

And Vadim's answer seemed to make the difference using a combination of actions. I was unable to check on his website to summarize the solution here, but was unable to see the site at the moment.

The web service that I wrote accept a byte [] for the file as argument.

I use the [FileData] in the workflow;  the Nintex workflow will convert the file to base64 and send it to the web service. Now my web service accept the file as a byte[]. Do you think this is the problem? Do I need to change the byte[] to string?

Thanks

[andrewg]

I don't believe it is a byte array, have you tried as an encoded string? I wasn't able to find the detail specs though. Vadim Tabakman​, do you know if it is a byte array?

It is working now. The problem was with the back end web service. I use a byte array for the document content in the web service and [FileData] in the workflow. Thanks for your reply.

That's great! Thank you for the response. Mark my response as an answer if it was a help.
