Launch PowerApps from SharePoint List "New" Button

[RameshMukka]

I am very much new to PowerApps. Please help me with this small issue. My PowerApps form have data connection to my SharePoint Online list. I would like to launch this PowerApp directly from SharePoint Online list when user tries to create a list item by clicking on "New" button on default SharePoint list page. How can I achieve this? Thanks a lot in advance.

You can launch a Customized SharePoint List by clicking the New button after you've created.

Customize A SharePoint List:

https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/customize-list-form

You CANNOT open a PowerApps Canvas App by clicked the new button in SharePoint.  Period.

This is an old post, but it may help other people.
You CAN open a Power App by clicking the new button in a SharePoint list, by setting the Customised SharePoint List form to open your Power App.

Go to your list, Expand the dropdown Power Apps >> and click on Customize forms
Power Apps will open. 
In the Tree view you will see SharePointIntegration and FormScreen1.

Delete all the Data cards under FormScreen1.
Select the SharePointIntegration and choose the property OnNew and enter:

NewForm(SharePointForm1);
Launch("https://apps.powerapps.com/play/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX?tenantId=XXXXXXXX-XXXX-XXXX-XXXX-XX...");
RequestHide()

The launch URL you get it's the WebLink of the Power App you would like to run + the parameter &hidenavbar=true

The WebLink you can find it in your App Details.

You can also pass additional parameter for example &ID=0 and in your Power App App>>OnStart you can handle the paramenter. For example: If(Param("ID")=0,NewForm(FORMNAME)).

When all done click Save your App and Publish to SharePoint

When you click on the new button in your list your Power App should launch.

Hi @capoaus75 just wanted to thank you for this - I'd found April Dunnam's earlier posts on how to redirect a SharePoint List New Item to a Canvas PowerApp but with her URL having been from a couple of years ago the formats had been changed by Microsoft - with your URL guidance (excluding the NewForm(SharePointForm1); actually) I was able to make my NewItem redirect to my on-premise app thanks SO much ...

This was really handy, thank you for sharing.

@capoaus75  This was great, thank you! What about opening an item directly from the SharePoint list in Edit mode? I'm struggling to get that piece to work.

Hi @abruno 

That should not be too difficult.

In your list  format one of the column to link to your canvas app and pass the ID of your item.

Enter the following JSON and update the XXXX values with the relevant data

{
"$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
"elmType": "a",
"txtContent": "@currentField",
"attributes": {
"target": "_blank",
"href": "='https://apps.powerapps.com/play/XXXXXXX-XXXXX-XXXXX-XXXX-XXXXXXXX?tenantId=XXXXXXX-xxxxx-XXXXX-XXXX-XXXXXX&ID='+[$ID] + '&hidenavbar=true'"
}
}

In your canvas app OnStart get the ID parameter and if the varID is not blank display the form in Edit mode otherwise display in view mode.

Set(
    varID,
    Param("ID")
);

If(
    Not(
        IsBlank(varID)
        ),
        EditForm(YourForm),
        ViewForm(YourForm)
   );

 Let me know if this works for you.

@mdevaney  I know this is an old post, but John Lui figured all this out for opening a PowerApps Canvas App from the SharePoint forms.

It is possible and it works quite well.

Who are you and where have you been my whole life?

i haven’t tried this out yet, but from reading it, im pretty sure you solved one of my biggest pet peeves of customizing a sharepoint list with power apps… 

when you create the app directly from the list, you lose a lot of the admin control you have over the Power App… I think you just solved that for me. You sir, are a savior.
