I have created automated approval flow which triggers when an item is added or modified in SharePoint list.

I have design approval screen in PowerApps so users can take actions from PowerApps also.

Q: Can we cancel or terminate power automate flow, if user approve or reject from PowerApps screen?

The only way to cancel an existing approval is to delete the approval request in the Dataverse Approvals table. This requires a Premium license and will not remove existing emails. But it will remove the pending approval from the Power Automate Approval site. To delete the Approval you will need to know the Approval ID. The ID is generated when the Approval is created. If you need to track the ID then use the two action steps "Create an Approval" and "Wait for an Approval". The ID will be available as output from the Create step.

This is interesting. That means if the approval is acted on within powerapps, we can have another flow run and delete the approval request. This is one those implementations that improve the general experience of solutions we build around power apps and power automate. NICE! Thank you for sharing.

Thanks!.
That means the only workaround is to first use crate an approval action and then use wait for an approval action.
If action taken from PowerApps then delete the approval from Dataverse using the ID of create an approval action.

That is correct. Also, remember every user will need to have a Premium license if you are going to delete the Approval in Dataverse from the Power App.

Yes, because of that premium Dataverse, I am using other way.
I have used create an approval action first and then I am saving that response link to my list and then using wait for an approval action.
when I am click on button it's redirect to that approval flow in power automate using launch() as below,
Launch(galViewProposals.Selected.'Approval Link',"", LaunchTarget.New);
but on power automate page I have to select response again.
Is there a way, I can pass parameter in Launch() and on power automate page in response dropdown, automatically select response (Approve, Reject) so user just have to click on submit button.

If you are launching the link I don't know of any way to pass the Accept or Reject along when you launch the link

I found a way to send parameters with link.
at the end of approval URL add like: URL&"&response=Approve/Reject". on power automate approval it will take response from URL.
Now I'm struggling with comments, I want to send comments also in parameter.

Also figured out another way to do this from this post https://www.about365.nl/2020/02/27/power-automate-approvals-markdown-or-html/ . You can create a url that points back to the approval from powerapps. That way approving or rejecting in powerapps still links to the approval created in Flow. All you have to do is have a column on your table to house the special url that will connect the user to the approval.

So the scenario is this,
Create and approval in flow, generate the urls for both approve and reject or whatever outcomes fit your situation. Pass those urls into your data. Create the wait for an aoproval action card and link it the initial approval you started. In power apps, when the user to asked to approve, onselect on the button launch the respective urls for approve or reject. The user is redirected to flow approval page. This way, approvals are apl tied back to flow either person sees it on the approval page or view the work item withing PowerApps. I hope this makes sense.
