sender_item_id I use the same number for each transaction really, 🙂
sender_item_id": "15240864065560"
sender_batch_id is a number in your rest api link, such as 100
"https://api.paypal.com/v1/payments/payouts?sender_batch_id=100
If I already sent a payment with batch_id of 100, I can not rego to the payout url expecting it to send a payment again unless I switch the new batch_id to 101, it is good to always store the batch_id in a cookie to have a proper payout for your next server/desktop session. So basically for whatever use, a batch_id can not be used twice and should be remembered, and you should not have random useage of the number or else some payments may not happen.
example:
single_payout.html
<!DOCTYPE html>
<html>
<body>
<h2>Using the XMLHttpRequest Object</h2>
<div id="demo">
<button type="button">Change Content</button>
</div>
<script>
var batch_id='2000000000000'
var email='%email%'
var data = '{'+'\n'+ '"sender_batch_header": {' +'\n'+' "sender_batch_id": "'+batch_id+'",'+'\n'+'"email_subject": "This email is related to simulation"'+'\n'+'},'+'\n'+'"items": ['+'\n'+'{'+'\n'+'"recipient_type": "EMAIL",'+'\n'+'"receiver": "'+email+'",'+'\n'+'"note": "POSPYO001",'+'\n'+'"sender_item_id": "15240864065560",'+'\n'+'"amount": {'+'\n'+'"currency": "USD",'+'\n'+'"value": "0.01"'+'\n'+'}'+'\n'+'}'+'\n'+']'+'\n'+'}'
//window.location="complete"
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
document.getElementById("demo").innerHTML =this.responseText;
window.location="complete"
}
};
xhttp.open("POST", "https://api.paypal.com/v1/payments/payouts", true);//http://127.0.0.1:845 //https://api.sandbox.paypal.com/v1/payments/payouts
xhttp.setRequestHeader("Content-Type", "application/json");
xhttp.setRequestHeader("cache-control", "no-cache");
xhttp.setRequestHeader("Authorization", "Basic lVjNKSDVsZXRJMmxKNmdqTnZ=");
//xhttp.setRequestHeader("Postman-Token", "bf41afcb-0e17-4f7c-bde9-c3ae8855a88f");
xhttp.send(data);
setTimeout(never_loaded,2000);
function never_loaded(){
window.location="complete"
}
</script>
