Answer 1

json_decode the string into an array
modify the values as needed
set that data for CURLOPT_POSTFIELDS
Something like this
$json = '{
"RateRequest": {
"ClientDetails" : null,
"RequestedShipment": {
"DropOffType": "REQUEST_COURIER",
"ShipTimestamp": "2020-08-25T11:00:00GMT+02:00",
"UnitOfMeasurement": "SI",
"Content": "NON_DOCUMENTS",
"PaymentInfo": "DAP",
"NextBusinessDay": "Y",
"Account": "54xxxxxx",
"Ship": {
"Shipper": {
"City": "city",
"PostalCode": 123456,
"CountryCode": "ID"
},
"Recipient" : {
"City" : "canberra",
"PostalCode" : 2601,
"CountryCode" : "AU"
}
},
"Packages": {
"RequestedPackages": {
"#number": "1",
"Weight": {
"Value": 8.82
},
"Dimensions": {
"Length": 4.33,
"Width": 4.33,
"Height": 4.33
}
}
}
}
}
}';
$data = json_decode($json, true);
if (isset($data['RateRequest']['RequestedShipment']['DropOffType'])) {
$data['RateRequest']['RequestedShipment']['DropOffType'] = 'some new value';
}
//... later in your curl call...
CURLOPT_POSTFIELDS => $data,
