Array payload to queue via API

I am using Add to queue item API to add below information in Queue. I want to add “Products” array to store multiple products detail and store into one transaction item .
But getting below error . Please guide me

Below is the payload :
{
“itemData”: {
“Priority”: “Normal”,
“Name”: “queue3”,
“SpecificContent”: {
“shopName”: “webshop”,
“srNumber”: “SR10036”,
“location”: “Germany”,
“EmailAddess”: “sathish@outlook.com”,

},
{
“Products”: [{
“productID”: “VM_580-ADFO”,
“productName”: “Jabra Evolve 40 UC Stereo”,
“qty”: 1
},
{
“productID”: “VM_7599-838-109”,
“productName”: “Jabra Evolve 40 UC Stereo”,
“qty”: 2

	}
]

}
}

the array needs to be serialized, then the resulting string can be used

I am adding this array value using postman…How to serialized in postman?

give a try and surround the array [ ] by " and check it if inner " are to escape with \

"Products":"[{
\"productID\": \"VM_580-ADFO\",
\"productName\": \"Jabra Evolve 40 UC Stereo\",
\"qty\": 1
},
{
\"productID\": \"VM_7599-838-109\",
\"productName\": \"Jabra Evolve 40 UC Stereo\",
\"qty\": 2
}]"

another option could be to use a variable and serialize the array by JSON.stringify method

I have added the queue name and priority. Please find error in above screenshot
{
“itemData”: {
“Priority”: “Normal”,
“Name”: “queue3”,
“SpecificContent”: {
“Products”: "[ {“
productID”: "VM_580 - ADFO ",
“productName”: “Jabra Evolve 40 UC Stereo”,
“qty”: 1
},
{

productID”: “VM_7599 - 838 - 109”,
“productName”: “Jabra Evolve 40 UC Stereo”,
“qty”: 2
}]
"}
