How to invoke a qlik sense task from command line

But if you need to check status after execution, get details of the task or any other entity of Qlik Sense (user, app, license, etc) then you have to use a library or package that performs all that kind of funcionality.

I wrote a simple npm package qlik-sense-qrs that can help you to write more complex scripts that will allow you to interact with Qlik Sense in a more efficient way.

The package is available at github and there you will find some basic documentation on how to install and use it.

Basically, all you will need is adding the package to your project

npm install qlik-sense-qrs --save 

Once the package and its dependencies are installed you are ready to use it.

You will need a Qlik Server certificate to authenticate to the QRS API. There are some basic directions on how to get your server certificate in the post mentioned above.

Put both files containing the certificate and the key in a secured folder to make sure only your application has access to them.


Now you are ready to import and configure the library to access your server from your Node.js application:

const qsqrs = require('qlik-sense-qrs');

//Set an array of options
let options = {
    host: 'https://yourserver:4242/qrs',
    //Path to your server certificates
    certFile: '../../qlik/client.pem',
    certKeyFile: '../../qlik/client_key.pem'
//Apply defined configuration
//Show the current configuration

That is the simplest way to set the connection options: you create an object containing three mandatory parameters and pass it to the apply method of the config object.

The next two lines are optional. They just show the applied configuration to you, like this:

  host: 'https://yourqliksenseserver:4242/qrs',
  certFile: '../../qlik/client.pem',
  certKeyFile: '../../qlik/client_key.pem',
  xrfKey: '43f0a598891d850d',
  certPassword: ''

You will notice there are two more parameters that you didn’t specify: xrfKey and certPassword. Let’s explain what they are.

  • xrfKey: This is a 16 characters long string used to prevent CSFR attacks. The key will be sent in the query string and also as a header of the request. If you don’t specify a key, the library will create a random one for you, but if you want to use your own (can’t imagine a reason) all you have to do is adding it to the configuration object or invoking the specific method to set it:
  • certPassword: when exporting your server certificate you can specify a password to improve the security. At the moment of writing this post the library hasn’t implemented this option, but probably in the next version will be available.

You can set and get any of the configuration parameters by using their corresponding method in the config object (qsqrs.config):

  • qsqrs.config.setHost(‘host url’)
  • qsqrs.config.getHost()
  • qsqrs.config.setCertFile(‘certificate file location’)
  • qsqrs.config.getCertFile()
  • qsqrs.config.setCertKeyFile(‘certificate key file location’)
  • qsqrs.config.getCertKeyFile()
  • qsqrs.config.setXrfKey(‘Your own key’)
  • qsqrs.config.getXrfKey()
Accessing the entities of Qlik Sense

There are two different types of objects in the wrapper. All of them are implemented in the entities object.

  • genericEntity: Most of the objects of QRS API have a get (list or read) endpoint and the structure of the subjacent request is the same for all of them. What the genericEntity does is receiving the name of the Qlik Sense entity as a parameter and perform the requested method. For instance, I don’t know what the odagrequest object is used for, but using the genericEntity object I can perform a call like the following and get some results:
let data = await qsqrs.entities.genericEntity.list('odagrequest');

You can check some more examples in the Github page or inside the test code.

There is an array inside generic-entity.js file that defines which objects you can invoke to:

const allowedEntities = [
    'about', 'analyticconnection', 'app', 'appavailability', 'appcomponent',
    'appcontentquota', 'appseedinfo', 'appstatus', 'binarydelete', 'binarydownload',
    'binarysyncruleevaluation', 'compositeevent', 'compositeeventoperational', 'compositeeventruleoperational',
    'contentlibrary', 'custom', 'custompropertydefinition', 'dataconnection',
    'engineservice', 'event', 'eventoperational', 'executionresult', 'executionsession',
    'extension', 'externalprogramtask', 'externalprogramtaskoperational', 'fileextension', 'fileextensionwhitelist',
    'filereference', 'health', 'license', 'licenseaccessusage', 'lock',
    'mimetype', 'odagenginegroup', 'odaglink', 'odaglinkusage', 'odagmodelgroup',
    'odagrequest', 'odagservice', 'printingservice', 'proxyservice', 'proxyservicecertificate',
    'reloadtask', 'reloadtaskoperational', 'repositoryservice', 'schedulerservice', 'schemaevent',
    'schemaeventoperational', 'selection', 'servernodeconfiguration', 'servernodeheartbeat', 'servernoderole',
    'servicecluster', 'servicestatus', 'sharedcontent', 'staticcontentreference', 'staticcontentreferencebase',
    'stream', 'syncsession', 'systeminfo', 'systemnotification', 'systemrule',
    'tag', 'task', 'taskoperational', 'tempcontent', 'user',
    'userdirectory', 'userdirectoryconnector', 'usersynctask', 'usersynctaskoperational', 'virtualproxyconfig',
  • task: By now, this is the only object that implements a method different of a list or read one. It implements a start method, which is the one we are naming since the first line of this post.
Putting it all together

The example below shows how to search for a task based on its name. Then, retrieve its id to invoke the task and after that it waits for 5 seconds and shows the execution result.

const qsqrs = require('qlik-sense-qrs');
let options = {
    host: 'https://yourserver:4242/qrs',
    //Path to your server certificates
    certFile: '../../qlik/client.pem',
    certKeyFile: '../../qlik/client_key.pem'
//End of initialization

(async() => {
    try {
        let name = 'My task name';
        console.log('Retrieve task data by name');
        let data = await qsqrs.entities.task.list(`name eq '${name}'`);
        let id = data[0].id;
        console.log(`Task id is ${id}\nStart task specifying its id`);
        data = await qsqrs.entities.task.start(id);
        console.log('Task started. Wait for 5 seconds....');
        await qsqrs.util.wait(5000);
        console.log('Retrieve task data by id');
        data = await qsqrs.entities.task.list(`id eq ${id}`);
        console.log('Show execution / progress result');
        let execData = data[0].operational.lastExecutionResult;
    } catch (err) {

How to invoke a Qlik Sense task from the command line

If you use Qlik Sense, eventually you will need to automate the execution of the data loading tasks.

Qlik Sense implements a REST API to make this and much more things. It is called Qlik Sense Repository Service API or QRS API

There are several ways to authenticate our calls to the server. Here we will use a server certificate instead of Windows or HTTP Header Authentication.

To export the server certificates, we need to access the QMC console with admin privileges. Once you are logged into the QMC, click in the last option on the left menu “Certificates”.

Exporting Qlik Sense server certificatesYou will need to enter a machine name and also a password if you want to protect your certificate. Remember, if you don’t specify a password, anyone who has access to the certificate file will have the capabilities of an admin via the Qlik Sense API.

Change the file format of the certificate to .pem and note the location where the .zip file that contains the certificates will be saved.

If you go now to the folder mentioned above and everything went ok, you will find a zip file. Unzip the file and copy both files inside (client.pem & client_key.pem) into a safe folder or an usb pen that we will reference later. 

Now, let’s go to our Linux station to create the utility script that we can use to start Qlik Sense tasks.

Of course, the Qlik Sense server has to be accessible from this station.

1.- Create a folder to store both the script and the certificate files

mkdir /opt/qliktasks

2.- Access the new folder and create a new one to store the certificate files

cd /opt/qliktasks

mkdir cert

3.- Copy the cert files from your usb device or the folder where you stored them before. Once you’ve finished, there should be two files inside the cert folder you created in step 2.



4.- Now, let’s create the sh script:

4.1.- Inside /op/qliktasks folder open nano or vim to create the file


4.2.- Make up a 16 characters long key that you will specify later in the query string and a header of the curl request. For instance:



4.3- Copy the following content inside the file updating the files path and the 16 long key. This is a very important step because the files need to be specified with an absolute path.


curl --key /opt/qliqtasks/cert/client_key.pem \
--cert /opt/qliqtasks/cert/client.pem \
--insecure \
-X POST \$1/start?xrfkey=MySixteenLongKey \
--header "Content-type:application/json" \
--header "x-qlik-xrfkey: MySixteenLongKey" \
--header "X-Qlik-User: UserDirectory=internal;UserId=sa_repository" \
-d ""

4.4.- Save the file (CTRL + O), confirm and exit (CTRL + X) the editor

4.5.- Activate execution flag

chmod +x

5.- Now we are ready to execute a Qlik Sense task by specifying its UUID.

./ e12ed06d-9124-4772-a07d-60cc06f05521

How to find the task UUID?

Go to QMC tasks panel and find the column menu in the top right corner. Simply activate the ID checkbox and copy from the new column the UUID of the task you need to invoke.
