Code Sample in C#

Note: Your agreement with AssureSign may cap the number of documents that may be attached per envelope.  Regardless of any explicitly designated cap, abuse of envelope operations may be cause for limiting your account activity.  Documents submitted explicitly to a named EnvelopeId are not parsed or processed until the CloseEnvelope operation is invoked.  Because of the relationship of documents within an envelope and the need to maintain their presentation order, the CloseEnvelope operation executes synchronously on associated documents in order of submission.  Therefore, submitting large amounts of documents within an envelope will be self performance-limiting.  For best performance, we do not recommend submitting more than 10 documents within an envelope.

The CloseEnvelope operation allows a document envelope to be closed and the signing process to be started. When this operation is called, the signing process will be immediately started for one or more documents in the envelope (depending on whether the envelope is configured for parallel or sequential signing workflow).

In addition, it is not possible to add any additional documents to an envelope after the envelope has been closed.

The CloseEnvelope operation requires knowledge of the following:

  • The EnvelopeId of the envelope to close (this is returned as an element in the returned XML from an envelope creation operation)
  • The AuthToken of the envelope to close (this is returned as an element in the returned XML from an envelope creation operation)
  • The AssureSign account ContextIdentifier (this is exposed in the AssureSign administrative application account settings and serves to provide some security to the transaction)

Sample XML

<?xml version="1.0" encoding="utf-8"?> 
<CloseEnvelope xmlns=""> 
    <Request ContextIdentifier="06C4A84A-693C-46CB-8DF2-40A8215AA056" EnvelopeId="2CE11EF1-8938-DD11-8735-00065B8CE99B" AuthToken="8CC9A84B-693C-46CC-4342-40A8215AD76A" /> 

The SOAP Action Header is

A simple response is returned echoing the envelope information which will only contain an Exceptions node if some issue has occurred:

<?xml version="1.0" encoding="utf-8"?> 
<CloseEnvelopeResponse xmlns=""> 
    <CloseEnvelopeResult EnvelopeId="2CE11EF1-8938-DD11-8735-00065B8CE99B" /> 

The CloseEnvelopeResult should be checked for the presence of an Exceptions element, which may contain multiple EnvelopeException items.
