Trying to configure Flow to do a simple POST using Send an HTTP request to SharePoint. So far no luck, I get the following output:

"status": 400, "message": "A type named 'SP.Data.WF_NotifierListItem' could not be resolved by the model.

Any suggestions?

UPDATE

After giving up on this a year ago I'm back for more punishment. Stumbled across a post that revealed method ListItemEntityTypeFullName to resolve type.

eg: _api/web/lists/getbytitle('WF_Notifier')?$select=ListItemEntityTypeFullName

I've googled, read posts, tried several examples and variations, still no luck. It can't be that bloody hard to send a simple update request through Flow.

Here's my latest attempt, hard wiring the itemid until I get some kind of success. This results in:

The parameter Title does not exist in method GetById

Heres another variation using odata=verbose in Content-Type, attempting to declare metadata in body, and trying to update 'TestColumn' just in case it didn't like Title for some reason. This results in:

The parameter __metadata does not exist in method GetById

Replace 'Title':'hello world' with Title:'hello world'

Always remember: Do not put '' on column name.

A 400 means that the request was malformed. error code detail

The solution was simply to use PATCH, not POST.

If you change your headers, you can get rid of the metadata attribute in your body.

By changing the Content-Type value to application/json;odata=nometadata you can simply send the body as 

{
    "Title": "Hello World!"
}

and this should at least remove the error of the incorrect metadata flag.

Hope this helps!

After the Patch request successful updated the item, do you have a problem with more than 20 history-versions created for that item? (I checked and sure the http patch request sent only ONE time)

thanks
