Reply Flags

The following table lists the PayPal Express Checkout reply flags returned by the SCMP API. See the information about handling replies in Getting Started with CyberSource Advanced for the SCMP API for a discussion of replies and reply flags.

Because CyberSource can add reply fields, reply codes (rcode), reply flags (rflag), and reply messages (rmsg) at any time, do the following: ■ Parse the reply data according to the names of the fields instead of their order in the reply. For more information about parsing reply fields, see the documentation for your client. ■ Program your error handler to use the reply flag value to determine the result if it receives a reply code that it does not recognize.

Reply Flags

Reply Flag	Description
SOK	Successful transaction.
DMISSINGFIELD	The request is missing one or more required fields.
DINVALIDDATA	One of the following: ■ One or more fields in the request contain invalid data. ■ General decline by PayPal. Possible action: request that the customer selects a different form of payment at the PayPal web site. ■ There is a problem with your CyberSource merchant configuration. Possible action: do not resend the request. Contact Customer Support to correct the configuration problem.
ESYSTEM	System error. You must design your transaction management system to include a way to correctly handle CyberSource system errors. The error might indicate a valid CyberSource system error, or it might indicate a PayPal rejection because of some type of invalid data. In either case, CyberSource recommends that you do not design your system to endlessly retry sending a transaction in the case of a system error. See the documentation for the CyberSource client you are using for important information about how to handle system errors and retries.
ETIMEOUT	Error: The request was received but there was a server timeout. This error does not include timeouts between the client and the server. Possible action: To avoid duplicating the transaction, do not resend the request until you have reviewed the transaction status in the Business Center. See the documentation for your CyberSource client for information about how to handle retries in the case of system errors.
DPAYMENTREFUSED	PayPal rejected the transaction.
