PayPal Name-Value Pair API Basics
Responding to an NVP Response
1
24 August 2012 Name-Value Pair API Developer Guide
In this case, the parameter ID is ProcessorResponse, which indicates an error response by
a credit or debit card processor. The value contains the processor-specific error. These values
are not set by PayPal; rather, they are passed through from the source.
NOTE: PayPal only passes selected values in the L_ERRORPARAMIDn and
L_ERRORPARAMVALUE
n fields.
URL Decoding
All responses to HTTP POST operations used by the PayPal NVP API must be decoded.
The PayPal NVP API uses the HTTP protocol to send requests and receive responses from a
PayPal API server. You must decode all data returned using the HTTP protocol so that it can
be displayed properly. Most programming languages provide a way to decode strings.
