How to retrieve wiki links attached to a Work Item

Question

I am trying to extract wiki links from Azure DevOps using the azure-devops python package. Is this something feasible to do using WIQL? Retrieving item-to-item links can be done like this:

        SELECT * FROM workitemLinks 
        WHERE (Source.[System.AreaPath] Under 'devOpsTesting\\testArea')
        AND ([System.Links.LinkType] = 'System.LinkTypes.Hierarchy-Forward')
        AND (Source.[System.Id] = 3)  
        ORDER BY [System.Id]
        MODE (Recursive)

Is there a similar solution for wiki links, if not how would one retrieve them?

We cannot list the work links for wiki links via WIQL query. If the link does not contain work items, we could not get the result we want.

As a test result, I found that if we link wiki to work item, the value of field External Link Count will be greater than 0.

As a workaround, we could use REST API to list all work items that External Link Count is greater than 0.

REST API

POST https://dev.azure.com/{Org name}/{Project name}/{Team name}/_apis/wit/wiql?api-version=6.0

Request Body:

 {"query": "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.TeamProject] = @project and [System.WorkItemType] = 'User Story' AND [External Link Count] > '0' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc"
}

Now, we could list work item IDs.

Result:

Then we check the work item detail info via REST API.

GET https://dev.azure.com/{Org name}/{Project name}/_apis/wit/workitems/{Work item ID}?$expand=all&api-version=6.1-preview.3

We need notice the field relations.attributes.name, If the work item links wiki, we could check it via this field.

Result:

List work item IDs via REST API and power shell.

Power shell script:

$connectionToken="{PAT}"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$WorkItemQueryURL = "https://dev.azure.com/{Org name}/{project}/{team name}/_apis/wit/wiql?api-version=6.0" 

$body =@"
{
  "query": "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.TeamProject] = @project and [System.WorkItemType] = 'User Story' AND [External Link Count] > '0' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc"
}
"@
$WorkItem = Invoke-RestMethod -Uri $WorkItemQueryURL -ContentType "application/json" -Body $body -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)} -Method POST

#Write-host $WorkItem.workItems.id



ForEach ($ID in $WorkItem.workItems.id)
{
 
 $WorkItemInfoURL = "https://dev.azure.com/{org name}/{project name}/_apis/wit/workitems/$($ID)?" + "$" + "expand=1&api-version=6.1-preview.3" 
 $WorkItemInfo = Invoke-RestMethod -Uri $WorkItemInfoURL -Headers @{authorization = "Basic $base64AuthInfo"} -Method Get

 #Write-host   $WorkItemInfo.relations.attributes.name

 if ($WorkItemInfo.relations.attributes.name -eq "Wiki Page"){  
  Write-host $ID
 }

}

Result:

Rest API:

GET https://dev.azure.com/{Org name}/{project name}/_apis/wit/workitems/{wok item ID}?$expand=all&api-version=6.1-preview.3

Result:

We could get the wiki name via the response url link.
