DownloadZipWithHandler

# DownloadZipWithHandler API

Stages a zip archive of specified documents and folders on the server and returns a download handler GUID for subsequent chunked retrieval via DownloadFileChunk. Unlike DownloadZip, this API returns XML (not raw bytes), supports partial results, and provides log details when items cannot be included.

Endpoint¶

/srv.asmx/DownloadZipWithHandler

Methods¶

GET /srv.asmx/DownloadZipWithHandler?authenticationTicket=...&Paths=...&partialResult=...
POST /srv.asmx/DownloadZipWithHandler (form data)
SOAP Action: http://tempuri.org/DownloadZipWithHandler

Parameters¶

Parameter	Type	Required	Description
`authenticationTicket`	string	Yes	Authentication ticket obtained from `AuthenticateUser`.
`Paths`	string	Yes	Pipe-separated (`\\|`) list of infoRouter paths to include in the zip. Each entry can be a full path to a document or folder, or a short ID path (`~D{id}` for a document, `~F{id}` for a folder). Paths that cannot be resolved are silently skipped.
`partialResult`	bool	Yes	Controls behavior when some items cannot be included in the archive. `false` — fails if any errors occur during zip creation (strict mode). `true` — succeeds and returns a handler even if some items were skipped, as long as the archive was created (partial mode).

Paths Format¶

Multiple items are separated by a pipe character (|):

/MyLibrary/Reports/Report.pdf|/MyLibrary/Slides|/OtherLibrary/Notes/Note.docx

Response¶

Success Response¶

<Response success="true" downloadhandler="a1b2c3d4-e5f6-7890-abcd-ef1234567890" error="" />

If some items were skipped during a partial result zip, error is set to "[log]" and child log elements describe which items were excluded:

<Response success="true" downloadhandler="a1b2c3d4-e5f6-7890-abcd-ef1234567890" error="[log]">
  <!-- log entries describing skipped items -->
</Response>

Attribute	Description
`success`	`true` if the zip archive was created and the handler is ready.
`downloadhandler`	GUID identifying the staged zip file. Pass this to `DownloadFileChunk` to retrieve the archive in chunks, then to `DeleteDownloadHandler` to clean up.
`error`	Empty string if no errors occurred. `"[log]"` if child log elements are present describing items that could not be included.

Error Response¶

<Response success="false" error="[log]" downloadhandler="">
  <!-- log entries describing the failure -->
</Response>

Required Permissions¶

Any authenticated user with read access to the specified documents and folders may call this API.

Chunked Download Workflow¶

DownloadZipWithHandler (this API) — Stage the zip archive and obtain a downloadhandler GUID.
DownloadFileChunk — Download the archive in sequential chunks using the handler GUID, advancing StartOffset by chunklength after each call, until lastchunk="true".
DeleteDownloadHandler — Clean up the handler and the temporary zip file on the server.

Example¶

GET Request (strict mode)¶

GET /srv.asmx/DownloadZipWithHandler
  ?authenticationTicket=3f2504e0-4f89-11d3-9a0c-0305e82c3301
  &Paths=/MyLibrary/Reports/Report.pdf|/MyLibrary/Slides
  &partialResult=false
HTTP/1.1

GET Request (partial mode)¶

GET /srv.asmx/DownloadZipWithHandler
  ?authenticationTicket=3f2504e0-4f89-11d3-9a0c-0305e82c3301
  &Paths=/MyLibrary/Reports|/Archive/OldDocs
  &partialResult=true
HTTP/1.1

POST Request¶

POST /srv.asmx/DownloadZipWithHandler HTTP/1.1
Content-Type: application/x-www-form-urlencoded

authenticationTicket=3f2504e0-4f89-11d3-9a0c-0305e82c3301
&Paths=/MyLibrary/Reports/Report.pdf|/MyLibrary/Slides
&partialResult=false

SOAP Request¶

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:tns="http://tempuri.org/">
  <soap:Body>
    <tns:DownloadZipWithHandler>
      <tns:authenticationTicket>3f2504e0-4f89-11d3-9a0c-0305e82c3301</tns:authenticationTicket>
      <tns:Paths>/MyLibrary/Reports/Report.pdf|/MyLibrary/Slides</tns:Paths>
      <tns:partialResult>false</tns:partialResult>
    </tns:DownloadZipWithHandler>
  </soap:Body>
</soap:Envelope>

Notes¶

Unlike DownloadZip, this API returns XML — the zip archive is not returned directly. Use the downloadhandler GUID to retrieve the zip in chunks via DownloadFileChunk.
The error="[log]" value is a literal signal that child log elements are present in the response body describing which items were skipped or failed.
With partialResult=false (strict mode), if any document or folder cannot be added to the archive, the entire operation fails and no handler is returned.
With partialResult=true (partial mode), the operation succeeds as long as the zip file was created, even if some items were excluded. Check for error="[log]" and inspect log entries to see what was skipped.
System-configured zip restrictions apply: if the total document count or combined file size exceeds the configured limits, the operation fails.
When including a folder path, all documents within that folder and its sub-folders are included in the archive.
Always call DeleteDownloadHandler after finishing the chunked download to free temporary server storage.

DownloadFileChunk - Download chunks of the staged zip archive using the handler GUID
DeleteDownloadHandler - Clean up the download handler after all chunks are retrieved
DownloadZip - Download a zip of documents and folders as a raw byte array in one call (suitable for small archives)
GetDownloadQue - Get the list of items in the current user's download queue

Error Codes¶

Error	Description
`[900] Authentication failed`	Invalid or missing authentication ticket.
`[901] Session expired or Invalid ticket`	The ticket has expired or does not exist.
No valid paths	None of the provided paths resolved to a document or folder.
Zip size or count restriction exceeded	The selection exceeds system-configured zip limits.
`[log]` (with `success="false"`)	Zip creation failed; inspect child log elements for details.
`SystemError:...`	An unexpected server-side error occurred.
