I registered an SharePoint Add-in using ...pwa/_layouts/15/AppRegNew.aspx but I did an writing error on the "Redirect URI:" and because of that my Add-in is not working.

Is there an Page ware I can manage my registered apps or what is the best solution for this Problem?


You can go to the following link and delete your app and permission from here


You find all your registered app here.


Go to SharePoint site contents and return to classic experience (if in SharePoint Online)

  1. Right click on the app
  2. Click "Remove"

enter image description here


You can go to the following URL http://.../_layouts/15/AppInv.aspx and on this page you can get the info for your App details.

On the following Link _layouts/15/appregnew.aspx you can update the settings.

Actually you can safely create new one with valid redirect uri, you can even have many applications pointed to the same redirect uri.


The solution that worked for me: Deleting the app per powershell Original poster: https://stackoverflow.com/a/36549952/6445723

Here are the steps as they have change since that post:

  1. Get the AzureAD PowerShell module - As Administrator run Install-Module -Name AzureAD

  2. Open a new PowerShell window and type Connect-AzureAD and login using your credentials (include @onmicrosoft.com or whatever custom domain you are using)

  3. Run Get-AzureADServicePrincipal and find your App name among the list. Copy the ObjectId

  4. Remove-AzureADServicePrincipal -ObjectId [your-app-id]

Done, the app is gone and you can register a new one. In SharePoint Online it seems to be the only working solution.
