google form custom connector

I implemented a flow with ms forms and trigger "when an answer is submitted", due to the limitation of ms forms not allowing to upload files to external users, I need to migrate to google forms, but there is no connector/trigger like ms forms. I know is possible to develop and I would like to ask for help to create and add the same trigger.
Is it possible? If so, can you tell me the step that I could accomplish?

I thought that we could leverage google sheet instead of google forms as a trigger.

Because the response is saved at a google sheet, I thought we can use the manipulation as a trigger.

However, there is NOT a trigger for google sheet at the moment.


I think this article might help you to solve the problem.

MS Forms, compared with G Forms, has some shortcomings but you may leverage the form in the Power Pages to overcome those defacts.

I, personally, recommend the form in Power Pages instead of G Forms.

The form feature of Power Pages looks much stronger and easier to integrate your work into MS 365 and Power Platform than G Forms.

The form feature of Power Pages allows you to attach a file as well.


Hopefully, you may get an answer.

Kind regards

Hi, thanks for your reply. From my understanding  Power Pages is just an app to easily create web pages in low code, but how can it overcome the limitation of ms forms that it doesn't allow to upload files to external people?

Hi @ralex,


As you said, Power Pages is an app to create a web page.

MS Forms and Google Forms is a kind of web page as well.


I believe this might be a good referance guide for you to add a form to your web page.

You can control to publish it to the public or keep it a private.

In order to make a good form to get the info, you need to design a table with Dataverse.

When you design the table, you will see all the options including a file upload feature.

These would help you to solve the problem.


I also created a demo web site (built by Power Pages) which has an event application form.

The form asks the name, phone number and email of the applicant.

As sood as the applicant submits the application via the web form, the answer works as a trigger to automate a flow to create a QR code and send it to the applicant (automated by Power Automate).

Power Apps helped me to create a QR code scanner to read the infomation in the QR code.


I recorded how to create a web form with Power Pages and automate with Power Automate and build a QR scanner with Power Apps.

Unfortuantely, I recorded those in Korean.

If you want to watch how to do those, you may visit a play list of these.

Actually, there's an option upload files in MS Forms.
However, it is only active for the internal users, as you might know.
