Workflow HTTP Unauthorized Error

Question

I created a SharePoint List workflow using SharePoint designer 2013 that created properly.

But when I started workflow manually I faced the following error.

SharePoint Workflow Unauthorized

Answer 1

SharePoint Workflow Unauthorized

Actually, this issue occurs if you didn't configure SharePoint Workflow Permissions Perporly.

To solve "SharePoint Workflow Unauthorized" error,

You should elevate the SharePoint Workflow permissions as the following:

• Allow workflow to use app permissions.
• Grant full control permission to the SharePoint workflow.
• Develop the workflow actions inside an App Step.

For the details steps, Please check SharePoint Workflow Unauthorized 401 error.

Answer 2

I got SharePoint Workflow unauthorized error because I was using the farm account to run the SharePoint Workflow

As a workaround I did the following :

• Added another user as a site collection administrator.
• Logged in to the site using this user.
• I tried to start the list workflow manually using this user.
• Workflow started normally without any issues.

Hi, Hesham Adding each user used to the site collection administrator is an incorrect and not practical solution. Instead, you should elevate the SharePoint Workflow permissions as mentioned at https://spgeeks.devoworx.com/sharepoint-workflow-suspended-unauthorized/
