I'm working through an advanced form.

I need a button to trigger a Power Automate Flow, and pass through the contact ID of the logged in user to that flow.

Is that possible?

Thanks
Lee

Thank you @OliverRodrigues that gives me most of what I need.

Is there an easy way to get the current logged in user of the Portal in JavaScript?

Also is it possible to get the session ID for the advanced form in the same way?

to get the user ID you can use a mix of Liquid and JS:

var userId = "{{user.id}}";

the session ID probably the best would be via URL, you can do this via JS or Liquid:

Liquid --> request.params["sessionid"]

JS -->

var urlParams = new URLSearchParams(window.location.search);
var sessionId = urlParams.get("sessionid");

I'm using the following code

        //build http request string using URL from Power Automate flow
        var req = new XMLHttpRequest();
        var url = "<<HTTP POST URL HERE>>";
        //send https request to Power Automate
        req.open("POST", url, true);
        req.setRequestHeader('Content-Type', 'application/json');
req.setRequestHeader('Access-Control-Allow-Origin', '*');
        req.send(courseupdate);
        alert("updated");

However I'm now getting a 400 error in my chrome console.

I've literally lifted most of this from a source that say's it's correct (though I added the Access-Control-Allow-Origin myself)
Is there a reason why this isn't working?

Worked out it was an error with the parameter I was passing.

I've put a redirect on the end of it, but it's failing to redirect. Is this more complicated than I'm trying?

req.send(sendID);

alert("updated");

window.location.replace('http://www.bbc.co.uk');

Oddly I can now relocate to the bbc website, but if i try a url that's within the portal it flatly ignores what I'm trying to do
