ERROR: The total invoiced amount for xxxxxx#gmail.com does not match the amount in the pay for delayed chain payment - paypal

Question

Error:
The total invoiced amount for xxxxxx#gmail.com does not match the amount in the pay for delayed chain payment.
I am not getting correct response for setPaymentOptions as here I am passing equal amount for both payrequst and invoice data but unable to compare their price. Is this because of currency code as here we pass currency code for payRequest receiver and for invoice data? We don't have any parameter as such for passing currency code. Can anyone help me out for this please?

Answer 1

Here 2 things are to be corrected related to price/amount to get rid of the error.
1: In the InvoiceItem object
[name] => Brand
[identifier] => 1
[price] => 256 //THIS IS EQUAL TO itemPrice * itemCount
[itemPrice] => 8.00
[itemCount] => 32
enter code here
2: In the Reciever object
xxxxxxx#gmail.com being the primary receiver should always have the amount equal to the total order amount (item + tax + discount + shipping), irrespective of if the secondary receiver is available or not. So it should be corrected to:
[amount] => 285.00 //256 + 2 + 27
[email] => xxxxxxx#gmail.com
[phone] =>
[primary] => true
[invoiceId] =>
[paymentType] =>
[paymentSubType] =>
[accountId] =>
And this Receiver object of secondary receiver specifies that out of total 285.00, 2.00 will be credited to the secondary receiver:
[amount] => 2.00 //2.00 will be credited to ABC out of 285.00
[email] => ABC-facilitator#gmail.com
[phone] =>
[primary] => false
[invoiceId] =>
[paymentType] =>
[paymentSubType] =>
[accountId] =>
Correct these and do let me know if you are still facing issue with amount mismatch.
