How Do I Change The Project Owner Using REST API

问题

I want to change the project owner of a project using REST API. I know there is a "/Owner" endpoint and I can get the owner without any problems with the following GET:

site/_api/ProjectServer/Projects('2cc734f2-cd16-4f09-8632-a2bc74a32577')/Owner

So how do I change the project owner using REST API?

回答1:

The general way to change site owners using REST API according to MSDN is:

POST http://<sitecollection>/<site>/_api/site/owner

So in your case you should just have to change from a GET command to POST

This is an old issue but I figured it might help someone since I recently struggeled with this too. I have only tested this on Project Online and not on-prem, probably works the same on Project Server 2016

1. Start by checking out the project

2. Send a PATCH request to:

   _api/ProjectServer/Projects('PROJECT ID')/Draft

   with the following headers:

   Accept: application/json; odata=verbose
   Content-Type: application/json; odata=verbose
   X-RequestDigest: The request digest
   If-Match: Either "*" or the etag value you get from checking out the project

   and the request body:

   { "__metadata": { "type": "PS.DraftProject" }, "OwnerId": "SharePoint User ID of the owner" }

   It's important that you send the "OwnerId" value as a string, not a number.

3. Publish the project
