SDK Logging

The PayPal SDK uses log4j public domain logging software. For complete information, see

the documentation at

http://logging.apache.org/log4j/docs/

Setting Log Levels

Set the value of the level element in SDK_root/lib/log4j.properties.

Logfile Backup

The default size of the SDK log is 10MB. You can set this size larger or smaller with the value

of param name=”MaxFileSize” in log4j.properties. When the log file reaches its

maximum size, a backup file is created and a new logfile begins.

ABLE D.4 SDK Logging Levels

Level Description

ALL Same as DEBUG

ERROR Log only severe errors

INFO Date/time of API operation, operation name, elapsed time, success or failure indication

DEBUG Full text of requests and responses and other debugging messages. Because DEBUG

logging can degrade the performance of the SDK, be careful about using it for day-to-

day operation.

N OTE: Because requests and responses are asynchronous, the recording of requests and

responses might appear out of sequence in the log file.
