I’ve checked your API and indeed such data is not supported by the DataGrid component. The grid expects array of objects with with same properties for every object instance similar to books in your Possible solution is to transform the the returned data to array of objects before binding the DataGrid.

Here is an updated application. There are a few things to consider:

  1. The sample service that you use doesn't support CORS. This would work only if the same origin policy is disabled.
  2. A transform is applied to the response so it is converted to array. The code is the following:

Object.keys(${result}).map(key => ${result}[key])

I could recommend using JSONPlaceholder for testing purposes. It comes with CORS enabled and has "DataGrid"-friendly responses. (6.0 KB)

jsonholder data.
