(
[description] =>
[customId] =>
[invoiceData] => InvoiceData Object
(
[item] => Array
(
[0] => InvoiceItem Object

[name] => my Item
[identifier] => 1
[price] => 138
[itemPrice] => 69

I followed the sdk example but I get this error response
SetPaymentOptionsResponse Object
(
[responseEnvelope] => ResponseEnvelope Object

[timestamp] => 2013-02-16T05:38:38.298-08:00
[ack] => Failure

)
[error] => Array
(
[0] => ErrorData Object
(
[errorId] => 580022
[domain] => PLATFORM
[subdomain] => Application
[severity] => Error
[category] => Application
[message] => Invalid request parameter: receiverOption.receiver(0).email
[exceptionId] =>
[parameter] => Array
(
[0] => ErrorParameter Object

[name] =>
[value] => receiverOption.receiver(0).email
)
[1] => ErrorParameter Object
(
[name] =>
[value] => [email protected]
)
)
)
)
)
If I don't set the email the error becomes Invalid request parameter: receiver cannot be null
Edit: Here and here you have some reference. Maybe you see something I didn't.
I was facing the same problem and found out that you need to provide a valid email address for receiver for the SetPaymentOptions call to succeed.
In my case I'm using chained payments and I use the email of the primary receiver.
