Starting a Task by Javascript

API & Customization Ask Developers

Does anyone know if it’s possible to start an Object’s task programmatically using Javascript?
Currently, only scheduled options are available but I need to do it on specific event, not cyclic period.

I dug deep into the Knack object and found task-related stuff but not sure how to use them.

Hello Normand,

Yes, you can do that but it explores your api keys.

Sure Brad,

try the below code it works for me.

$.ajax({
url: ‘https://eu-central-1-renderer-read.knack.com/v1/applications/**APPLICATIONID**/tasks/task_1/runtaskjob’,
type: ‘GET’,
headers: {
‘X-Knack-Application-Id’: ‘APPID’, // change to your app’s API info
‘X-Knack-REST-API-Key’: ‘KEY’. // change to your app’s key
},
success: function (response) {

    }
});

you need to change task_1 with you task id

Thanks

Sunny,

That’s pretty cool, thanks!

I’m very curious to know… where did you get that information?
Is there a full documentation of these functions somewhere?

Yep - same questions!
Tested and works BTW and could be obfuscated via a Make.com scenario.

Hello Normand,

There is no documentation for this.

Ok but then, how did you find out about the URL and the runtaskjob command?
I wonder what else is hiding that could be useful…

I partially answered myself.

In the console view, I had an error on a PUT and saw this URL:
https://us-east-1-renderer-write.knack.com/v1/scenes/scene_xxx/views/view_yyy/records/…

So I extracted the first part until the v1/ and tried this:
https://us-east-1-renderer-read.knack.com/v1/applications/APP_ID

Tadam! A ton of code appeared, and at the end, there were my server URLs:

    "clientSubdomainMap": {
      "read": [
        "us-east-1-renderer-read"
      ],
      "write": [
        "us-east-1-renderer-write"
      ]
    }

But that’s only a partial answer. What about the runtaskjob command?

Normand,

I also check this in the console. while running tasks manually.

Thanks,
