How to set person field in Flow: Send HTTP Request to SharePoint?

I've been playing with Flow: Send HTTP Request to SharePoint to create items in a list. Everything works great until I include the Person field: Assigned To.


error 400: A 'PrimitiveValue' node with non-null value was found when trying to read the value of a navigation property


Tried claims, display name, email...



Looking at the list item XML I see Assigned_x0020_ToId, so I guess I need to pass the numeric ID of the person. Do I need a step prior to resolve the user or look up their id?


Once I figure out this issue I would like to move on to something more advanced, like creating a list item for each person in a multiple person column...




FYI, I would have just used the available Create Item but Flow seems to ignore site column lookups.



Works in this example, haven't been able to replicate.


Using the native Create Item action in Flow requires additional actions (Send HTTP Request) to make up for OOTB deficiencies in recognizing site column lookups. Redundant and uneccessary item updates...

Re: How to set person field in Flow: Send HTTP Request to SharePoint?

The Assigned_x0020_To is the actual column name in the SharePoint list. If you navigate to the SharePoint list, and edit this specific column from the list settings, you'd see the URL path for the list contains this "proper name" of Assigned_x0020_To.

This likely means that the JSON that is being returned with the HTTP request isn't returning that specific column. Make sure that you setup a custom list view for the list that contains all of the columns you require, and then direct the HTTP request to that specific list view. 

If that doesn't work, you may need to opt to use the classic native Get Items SharePoint action against the custom view.

Hi @bdc604 ,


I think it's a good choice to use Create item action directly.

If you are experiencing problems with configuring the Person field when using Create item action, please provide more details.

In addition, you mentioned "but Flow seems to ignore site column lookups.", we also need relevant information so that we could provide proper workaround for you.
