POST multiple resources with Postman

Hi There,

Is there any possibility to create multiple records using Sage300 POST request? I tried using Postman to create multiple ARCustomers with following json format. But I keep getting the InvalidPayload error. Can someone please help me to provide the correct json structure?

[
{
"ShortName" : "1250 250user",
"GroupCode" : "ABC",
"Status" : "Inactive",
"RetainageTermsCode" : "ABC",
"AccountSet" : "USA",
"RateType" : "ABC",
"TaxGroup" : "ABC",
"Terms" : "ABC",
"StartDate" : "2018-07-13T00:00:00Z",
"CustomerNumber" : "1250"
},
{
"ShortName" : "1251 251user",
"GroupCode" : "ABC",
"Status" : "Inactive",
"RetainageTermsCode" : "ABC",
"AccountSet" : "USA",
"RateType" : "ABC",
"TaxGroup" : "ABC",
"Terms" : "ABC",
"StartDate" : "2018-07-13T00:00:00Z",
"CustomerNumber" : "1251"
}
]
this is the error I'm getting: 
{
"error": {
"code": "InvalidPayload",
"message": {
"lang": "en-US",
"value": "The payload is invalid for this resource.An unexpected 'StartArray' node was found when reading from the JSON reader. A 'StartObject' node was expected."
}
}
}
Cheers,
