This is working fine.

C#

public IHttpActionResult Post(Categories categories)
{
//...
}

But When I change Categories to Categories[] to received multiple records from javascript client, it show null object.

C#

public IHttpActionResult Post(Categories[] categories)
{
//...
}

from postman I've tried

post: {url}/odata/Categories
content-Type: application/json
body:
[
{ id: 1, Category: 'Value1' },
{ id: 2, Category: 'Value2' }
]

But I receive Null object at server side.

What I have tried:

{ id: 1, Category: 'Value1' },
{ id: 2, Category: 'Value2' }
