Hello,

I am wanting to set up a flow where when a QR code is scanned, the flow is triggered to automate. Any suggestions? I have tried using the "When an HTTP Request is Received" but have had no luck.

I think you will need to create a manually trigger flow. Then it would be just a matter of updating the URL to the flow to include run at the end: https://make.powerautomate.com/environments/environmentID/flows/flowID/run

This may not be exactly what you are looking to do since it will then open like this:

There may be other ways, but this is the only way I know of.

You are correct with the HTTP trigger.

What went wrong with it? Did you not set it so Anyone could trigger it or did you not set it to GET method or did you have trouble getting the HTTP url to be represented by the QR code?

Takolota1,

I set up the HTTP request trigger to GET for the method and I used "anyone" for the Who can Trigger The Flow option. I saved it to get the URL and then I went through an online QR code generator to make my QR code. Each Time I would scan it, it would say that the trigger was disabled and had an error message. See below for screenshots.

This is the error code that I would receive when scanning the QR code. I am not sure how to enable the trigger and I think that is my only current issue. I am very new to Power Automate so this may just be a silly error that I am making.
