reading rest response of particular attributes

Content

Hi Folks,

I am working on a poc and  getting rest response as below. My requirement is to read the AccountNumber from below and remove duplicates from them and use them to process further. eg: from below 3 records 6010,6010,6011 I should be able to get 6010,6011 as result. Any suggestions are highly appreciated. Thanks in advance. 

"items": [

        {

            "CustomerName": "cust2",

            "AccountNumber": "6010"

},

 {

            "CustomerName": "cust1",

            "AccountNumber": "6010"

},

 {

            "CustomerName": "cust1",

            "AccountNumber": "6011"

}

]
