Operations: Lists and List Items API

Using the Lists and List Items API lets you create, retrieve, update, and delete SharePoint lists and list items.

To Create, Update, and Delete List Items

When creating or updating an item, specify the list ID. After you specify an ID, DataSense fetches the list’s metadata and the object builder shows each field that can be completed:


          
       
1
2
3
<sharepoint-online:list-create config-ref="Sharepoint_Online" doc:name="Sharepoint Online" baseTemplate="GENERIC_LIST" title="Title">
  <sharepoint-online:list ref="#[payload]"/>
</sharepoint-online:list-create>

Or define the attributes in the connector itself:


          
       
1
2
3
<sharepoint-online:list-create config-ref="Sharepoint_Online" doc:name="Sharepoint Online" baseTemplate="GENERIC_LIST" title="Title">
  <sharepoint-online:list contentTypesEnabled="true" description="Description"/>
</sharepoint-online:list-create>

For retrieving and deleting lists, only the list ID is necessary:

<sharepoint-online:list-delete config-ref="Sharepoint_Online" doc:name="Sharepoint Online" listId="LIST_ID" />

When creating or updating an item, specify a list ID. DataSense uses the list ID to fetch a list’s metadata. The Object Builder provides the fields you need to complete.

sharepoint-online-mssp-object-builder

To Query List Items

Using the query builder:

In the left panel, each visible list appears. In the right panel, the fields of a selected list appear. If the field is a Lookup Field, use either SharepointListReference or SharepointListMultiValueReference.

sharepoint-online-query-builder

If any of these fields are selected to be returned by the query, two types of return objects are available, depending on the value of the Retrieve Full Objects for Reference Fields checkbox:

  • Not Checked: A summary object containing the reference object’s ID and the reference object list’s ID:

    
                 
              
    1
    2

    {
        "Title": "A title",
        "LookupFieldId": {
            "id": "1",
            "lookupListId": "aaaa-1111-bbbb-2222"
        },
        "MultiValueLookupFieldId": {
            "ids": [
                1,
                2,
                3
            ],
            "lookupListId": "cccc-3333-dddd-4444"
        }
    }

    Use this object with other connectors to retrieve the referenced object and with a for each component:

    sharepoint-online-mssp-list-item-query 

  • Checked: Retrieves the full object graph. In case there is a cycle, the summary reference object displays:

    {
        "Title": "A title",
        "LookupFieldId": {
            "Title": "Another title",
            "Id": "1",
            "Property1": "A value"
        },
        "MultiValueLookupFieldId": [
            {
                "Title": "Another title",
                "Id": "1",
                "Property1": "A value"
            },
            {
                "Title": "Another title",
                "Id": "2",
                "Property1": "A value"
            }
        ]
    }

Example Query Text:

sharepoint-online-example-q-text

Note: Checking this option may cause large item lists with many reference fields to take a long time to retrieve.

You can use the internal or title field names in DSQL queries, as well as in other list’s operations that follow.

For example for the previous query:

SELECT AuthorId, Created, List3MultiId FROM <LIST_ID>

Replace <LIST_ID> with the list ID.

If titles follow Author, Date created, and Details, you can write the query using field names:

SELECT Author, 'Date created', Details FROM Inventory

You can mix internal and title fields:

SELECT AuthorId, 'Date created', List3MultiId FROM Inventory

Using internal and/or title fields is only supported within the following list operations:

  • Adding a new item to the list

  • Updating an existent item in the list

  • Querying items in the list

Note: To filter by a datetime field type, write the value using ISO-8601 format when specified in a DSQL clause, for example: Created > 2017-01-01T00:00:00-03:00.

Operations: File and Folder API

Using the File and Folder API allows you to create, retrieve, update, delete files and folders, check in, check out, publish, approve, deny, copy, and recycle files from Documents Lists.

When using the folders operations, the server’s relative URL refers to where the folder is or will be. The URL can be in the format /site/docList/innerFolder or in docList/innerFolder  format. In the second case, the site specified in the connector’s configuration site URL parameter is used.

When using the files operations, the file server relative URL refers to a folder server relative URL plus the filename: /site/docList/innerFolder/filename or docList/innerFolder/filename.

To Create and Delete a Folder

You can create or delete a folder by specifying the relative URL of the server where the folder is or where you plan to create the folder.

The resulting flow appears as:


          
       
1
2
3
4
5
<sharepoint-online:folder-create config-ref="Sharepoint_Online" 
url="/path/to/folder" doc:name="Sharepoint Online"/>

<sharepoint-online:folder-delete config-ref="Sharepoint_Online" 
url="/path/to/folder" doc:name="Sharepoint Online"/>

To Add a File

Upload a file by selecting a physical file or passing an input stream to the connector. A file is uploaded to a server using a relative URL. For example, you can use this example with a File Connector to upload files to a list. 

Using an input stream:


          
       
1
2
3
4
<sharepoint-online:file-add config-ref="Sharepoint_Online" 
fileServerRelativeUrl="/path/to/folder/filename" 
fileContentStream-ref="#[payload]" overwrite="true" 
doc:name="Sharepoint Online"/>

To upload large files, configure your SharePoint and IIS servers:

  • Set the Maximum Upload Size to 2047MB (max) at the SharePoint management console for the site.

  • Set the connection timeout for the IIS site to a high value.

  • Set the Maximum Allowed Content Length to 2147483647 for an IIS app at request filtering.

Note: The SharePoint REST API that the connector uses supports uploading files up to 2 GB. When working with large files, provide the system local path to the file in the localFilePath parameter value. This is the most efficient way to upload a file through the connector.

To Get File Contents

The file content is returned as a byte array. For example, you can use this as an input of a File connector to download files from a list:


          
       
1
2
3
<sharepoint-online:file-get-content config-ref="Sharepoint_Online" 
doc:name="Sharepoint Online" 
fileServerRelativeUrl="/path/to/folder/filename"/>

To Get File Metadata

This operation requires only the file relative path:


          
       
1
2
<sharepoint:file-get-metadata config-ref="Sharepoint_Online" fileServerRelativeUrl="/Shared Documents/My File.txt" doc:name="Sharepoint Online">
</sharepoint:file-get-metadata>

To Update File Metadata

This operation requires that the relative path of the file and its key-value properties be updated. The following example shows how to rename a file and its title:


          
       
1
2
3
4
5
6
7
8
9
<sharepoint:file-update-metadata config-ref="Sharepoint_Online"
  fileServerRelativeUrl="/Shared Documents/My File.txt" doc:name="Sharepoint Online">
        <sharepoint:updated-properties>
                <sharepoint:updated-property
                  key="Title">New Title Value</sharepoint:updated-property>
                <sharepoint:updated-property
                  key="FileLeafRef">NewFileName.txt</sharepoint:updated-property>
        </sharepoint:updated-properties>
</sharepoint:file-update-metadata>

To Query Files and Folders

Querying returns all the files and folders that match the specified criteria, starting from the specified folder.

Using the query builder:

  • In the left panel, a document list from the SharePoint instance appears. The selected instance is used as part of the starting path to query the files and folders.

  • In the right panel, for every document list, the same fields appear.

  • Specify an inner folder or folders in the Folder Path input to use as the starting path.

  • When selecting the recursive checkbox, files and folders are searched recursively in every folder of the starting path.

To set query builder options:

sharepoint-online-folder-path

Example:


          
       
1
2
3
<sharepoint-online:file-query config-ref="Sharepoint_Online" query="dsql:SELECT Author,ModifiedBy,Name,ServerRelativeUrl FROM #[header:inbound:documentListName]" recursive="true" doc:name="Sharepoint Online"/>
 
<sharepoint-online:folder-query config-ref="Sharepoint_Online" recursive="true" query="dsql:SELECT ItemCount,Name,ServerRelativeUrl FROM #[header:inbound:documentListName] WHERE ItemCount &gt; 0" doc:name="Sharepoint Online"/>

About Other File Operations

You can Approve, Check In, Check Out, Deny, Publish, Undo Checkout, and Unpublish. Specify the file URL, and if needed, pass an additional comment as a parameter.


          
       
1
2
<sharepoint-online:file-publish config-ref="Sharepoint_Online" 
doc:name="Sharepoint Online" fileServerRelativeUrl="" comment=""/>

To Set File Metadata with the Update List Item Operation

You can get and set metadata on files to upload to document libraries by using the Update List Item operation.

To set the properties of the file in the list, you must know the List Item Id. This can be retrieved using the deferred ListItemAllFields property.

The following flow illustrates how a File Add may chain directly to an Update List Item operation to upload a file to a list and set the metadata immediately after:

       </sharepoint:updated-properties>
   </sharepoint:list-item-update>
   <set-payload value="OK" doc:name="Set Payload"/>
</flow>

To Resolve Deferred Properties

For performance reasons, many SharePoint operations return a basic set of data for an entity along with one or more deferred property references you can use to retrieve additional detail or related objects.

You can use the generic Resolve Object or Resolve Collection operations to resolve the deferred property set to a single Map<string,object> or a List<Map<string,object>> and access this information in the flow.

For example, this technique gets the full set of fields of a SharePoint File object:


         
      
1
2
3
4
<sharepoint:resolve-object config-ref="SharePoint" 
  url="#[payload.listItemAllFields.__deferred.url]" 
  doc:name="Microsoft SharePoint" >
</sharepoint:resolve-object>

Using the Mule Debugger or Logger component to log the payload, you can identify properties with a _deferred URL property.

To Attach a File to a List Item

To attach a file to a list item, use the ResolveObject operation:

    <sharepoint:list-item-query config-ref="Microsoft_SharePoint__Online_Connection"
     query="dsql:SELECT ID,Title FROM LIST_ID WHERE Title = 'test-list-item-1'" doc:name="Read List Item"/>
    <set-variable variableName="ListItemUrl" value="#[payload.next() .__metadata.uri]"

     resolveRequestType="Create" doc:name="create attachment"/>
    <json:object-to-json-transformer doc:name="Object to JSON"/>
</flow>

The flow shows how to:

  1. Get the list item URI by reading it from SharePoint. If you already have the list item because it’s being created in the same flow, you can use that one.

  2. Read a file into an input stream. Here it’s from c:\temp (find the path in the flow to replace it).

  3. Create the list item attachment with the file.

To Execute Direct Calls Using the REST API

SharePoint REST API allows a large number of commands that can be reached though Resolve Object and Resolve Collection actions. These operations provide an authenticated call to a specified URL, and resolves into a Map and a List<Map> respectively.

The Resolve Object operation accepts all the HTTP verbs (GET, POST, PUT/MERGE, DELETE) and allows sending a body in the request to the API. The body’s default value is the payload of the Mule message.

The body can be for API endpoints that accept a JSON:

  • Map<String, Object> converts to a JSON string.

  • String contains the JSON. This string is sent as-is.

For API endpoints that accept a file:

  • InputStream with the file. The stream closes after using it.

  • byte[] with the file. This byte arrays is sent as-is.

To Work with the Choice Column Type with Multiple Values

You can configure a Choice column type to allow multiple values. The metadata in Studio for columns accepting multiple values appears as follows:

sharepoint-online-choice-multi-select

Assuming that the target List in SharePoint has a Title property and a multi-select column called ChoiceMultiSelect that accepts values "one""two", or "three", the following Groovy script constructs a payload that sets the selection to "one", "three":

[Title: "foo", ChoiceMultiSelect: [results: ["one", "three"]]]

You can use any language that can construct a List<string> for the multi-select column results property.

The following pseudo code demonstrates how to set Choice #1 and Choice #2 as the values for the ChoiceMultiSelect column:


         
      
1
2
3
4
5
6
values = new List<String>
values.add("Choice #1")
values.add("Choice #2")
multiValuesMap = new Map<String, Object>
multiValuesMap["results"] = values
List-item["ChoiceMultiSelect"] = multiValuesMap

About Exception Handling

  • Exception When Connecting

    If the connector fails to connect with the SharePoint instance for any reason, an exception of type ConnectionException is thrown. The exception message helps debug the cause of the exception.

  • Exception in Operations

    If executing an operation an error occurs, a SharepointException is thrown with a message about the error.
