Paypal batch payout not working in node js api - node.js

Question

I am trying to create a batch payout with a test sandbox account.
The 'create payment' function is working absolutely fine with correct response:
var paypal_sdk = require('paypal-rest-sdk');
var config_opts = {
'host': host, //host defined
'port':'',
'mode':'sandbox',
'client_id': client_id, //clientID defined
'client_secret': client_secret, //clientSecret defined
};
var makePayment = function (req, res, next) {
var create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://mystore.in",
"cancel_url": "http://mystore.in/contact"
},
"transactions": [
{
"amount": {
"currency": "USD",
"total": "1.00"
},
"description": "This is the payment description."
}
]
};
paypal_sdk.payment.create(create_payment_json,config_opts, function (err, data) {
if (err) console.log("ERRRRR", err);
console.log("Create Payment Response");
console.log(data);
//res.send('201');
});
}
makePayment(); //CALLING THE FUNCTION
But, when I am trying to create a new payout, by editing create_payment_json as:
var create_payment_json = {
"sender_batch_header": {
"email_subject": "You have a Payout!",
"recipient_type": "EMAIL"
},
"items": [
{
"recipient_type": "EMAIL",
"amount": {
"value": "1.0",
"currency": "USD"
},
"note": "Thanks for your patronage!",
"sender_item_id": "201403140001",
"receiver": "shirt-supplier-one#mail.com"
}
]
};
And main function as:
paypal_sdk.payout.create(create_payment_json,config_opts, function (err, data) {
if (err) console.log("ERRRRR", err);
console.log("Create Payment Response");
console.log(data);
//res.send('201');
});
I am receiving an error as follows:
{ [Error: Response Status : 401]
response:
{ error: 'invalid_client',
error_description: 'Client Authentication failed',
httpStatusCode: 401 },
httpStatusCode: 401 }
However, I am sure that credentials passed are correct and they are working perfectly in case of payment creation.
I am doing all this for the testing first. Also, the payout feature is enabled for this respective test paypal developer account.
Is there any possible solution?

Answer 1

I just got the solution. Well, to add, I must say paypal should provide proper error handling to let the developers know the reason behind each error.
The error was because of the currency that I had set in the configuration. The testing developer account was of some other country and the currency code was set as "USD".
Just make a new account and set currency code in config according to the country you had selected during the creation of that test developer account.

Answer 2

I test payout , as below code, it works fine. You can compare your code with my sample, you can add'sender_batch_id' parameter to have a try.
curl -v https://api.sandbox.paypal.com/v1/payments/payouts/ \
-H "Content-Type:application/json" \
-H "Authorization: *****" \
-d '{
"sender_batch_header": {
"sender_batch_id": "batch_25",
"email_subject": "You have a payment"
},
"items": [
{
"recipient_type": "EMAIL",
"amount": {
"value": 0.99,
"currency": "USD"
},
"receiver": "aaabbb#email.com",
"note": "Thank you.",
"sender_item_id": "item_1"
},
{
"recipient_type": "EMAIL",
"amount": {
"value": 0.90,
"currency": "USD"
},
"receiver": "bbbb#gmail.com",
"note": "Thank you.",
"sender_item_id": "item_2"
},
{
"recipient_type": "EMAIL",
"amount": {
"value": 2.00,
"currency": "USD"
},
"receiver": "cccc#gmail.com",
"note": "Thank you.",
"sender_item_id": "item_3"
}
]
}'
