Start workflow using App only client context

Question

I use CSOM with client contex which I get from app, the App has following permissions:

<AppPermissionRequests  AllowAppOnlyPolicy="true">
  <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web" Right="FullControl"/>
</AppPermissionRequests>

I can normally work: create lists, libraries, etc..., but if I run workflow it going to suspend status and shows following error:

Retrying last request. Next attempt scheduled in less than one minute. Details of last request: HTTP Unauthorized to https://testsite.sharepoint.com/sites/HP/Test/_api/sp.utilities.utility.ResolvePrincipalInCurrentcontext?input='i%3A0i.t%7C00000003-0000-0ff1-ce00-000000000000%7Capp%40sharepoint'&scopes='15'&sources='15'&inputIsEmailOnly='false'&addToUserInfoList='False'&matchUserInfoList='true' Correlation Id: d0f3bddc-33e9-0d7c-a534-1c914cd47284 Instance Id: 5403283b-20a5-4855-8673-c40ef5ddfd94

Access denied. You do not have permission to perform this action or access this resource. Retry now

So my question, is it possible to run workflow using app only context?

Answer 1

I have found that it requires to has been activated the feature "Workflows can use app permissions" Also the workflow will be run under SHAREPOINT\APP user.
