HTTP-Request edit library item

Hello Power Automate Forum,

 

im trying to change the value of one column from a libary item, via the API.

Following the the offical documentay: https://docs.microsoft.com/de-de/sharepoint/dev/sp-add-ins/working-with-lists-and-list-items-with-re...

 

Getting the ListItemEntityTypeFullName:

 

_api/Web/Lists/getbytitle('Rechnungen')/ListItemEntityTypeFullName

 

 

I ended up with this:

error.PNG

 

Which leads to this error

 

Roughly translated
{
  "status": 400,
  "message": "The Parameter \"__metadata\" does not exist in the method \"SP.Data.RechnungenItem\" . 
}

 

 

I have tryed all kinds of Header configurations fors several hours. Starring at I dont know how many kinds of errors. Getting the information works fine, but edititing it seems impossible.

 

Can somone please point me in the right direction.

 

Best wishes,

Nico

I have used the below method to update the column values in the library using the HTTP request.

Try running the text with the following statement only.

{.
"Title" : "test"
}

If you still get an error, try deleting all the header content and running it once.
