Responses to Credit Card

Transaction Requests

This chapter describes the contents of a response to a credit card transaction request.

When a transaction finishes, PayPal returns a response string made up of name-value pairs.

For example, this is a response to a credit card Sale transaction request:

RESULT=0&PNREF=VXYZ01234567&RESPMSG=APPROVED&AUTHCODE=123456

&CVV2MATCH=Y

Contents of a Response to a Credit Card Transaction Request

All transaction responses include values for RESULT, PNREF, RESPMSG. A value for

AUTHCODE is included for Voice Authorisation transactions. Table 4.1 describes the values

returned in a response string.
