Logging Errors

Creating a log to capture any API errors is strongly recommended. It will be extremely helpful when you work with our API Support Team to troubleshoot errors. Be sure to log the exact timestamp of when the error occurred, the full error message and any available ids (merchant id, transaction id, etc) for error context. When sending log output to the PaySimple team, be sure to mention what time zone your log messages are in.
