How to pass 2D array of integer type to the Web API using POST

I need to pass an 2D array of any size, say a chess board, to a .net Web API controller action and need to test it with POSTMAN too.

The POST method needs to be used for posting the matrix.

Something like..

[1,2,3,4]
[1,0,1,0]
[0,1,0,1]
