I'm implementing a library to export/synchronize test cases into TFS automaticaly during test run. One of my requirements is that I need to use NodeJS, so I decided to use TFS REST API. In my code I'm using azure-devops-node-api lib. I can connect and get different elements, but I'm unable to add test cases.

I've found on the web that a TestCase is a kind of WorkItem and as WI should be added. Unfortunately I didn't find a way to add one with azure-devops-node-api.

I also tried to send manually constructed json, but no luck with finding proper url to send as I'm always getting:

Error: {"statusCode":404,"body":"Page not found."

My example request:

        url: 'https://<url>/tfs/<default collection maybe?>/<project>/_apis/wit/workItems/test%20case',
        headers: {
            'Content-Type': 'application/json',
            'Authorization':'Basic ' + this.encodePat('<my auth token>')
        rejectUnauthorized: false,//add when working with https sites
        requestCert: false,//add when working with https sites
        agent: false,//add when working with https sites
        json: rq
    },function (response, err, body){

        if (err) throw new Error(JSON.stringify(err));


Does anyone know what I'm doing wrong or if azure-devops-node-api is able to add WorkItems?

  • I'd suggest starting here: docs.microsoft.com/en-us/rest/api/azure/devops/… and working with Postman or a similar tool until you have the connection information and URL structure confirmed. You'll also want to make sure you've got the correct API version information for your TFS version

  • I've found my error - I missed '$' sign before WorkItemType in URL :) so proper path is: /_apis/wit/workItems/$test%20case?api-version=2.0
