Before taking any action, please refer to the Frequently Asked Questions section, where many common issues have been already explained and solved.

Event logs

The Pay with Amazon extension provides a convenient logging system. It is disabled by default, but you can enable it in the extension settings, refer to the Enable logging section for more details.

Log files location

The Logger saves details concerning all exceptions, all API calls and all incoming IPN notifications that occurred within the Pay with Amazon extension scope. Logs are stored in CSV files in the following locations:

  • exceptions logs:


  • API calls logs:


  • IPN notifications logs:


Logs accessing

In case you encounter any issues and Frequently Asked Questions section didn’t help, you should review your logs in the next step. Logs can be accessed in two ways:

  • Using creativestyle ‣ Pay with Amazon ‣ Log preview feature, where all logs are displayed on a convenient list with basic filtering options.
  • By directly accessing (using FTP, SFTP or SSH, depending on your server configuration) the above files on your server. After the download you can open them with any CSV-capable application. The current log files can be also downloaded by pressing Download as CSV button on the logs list creativestyle ‣ Pay with Amazon ‣ Log preview in the Magento admin.

Logs rotating

All log files are rotated as soon as they exceed the size of 8 Megabytes, the old log file is renamed then to var/log/amazonpayments/apa_*.log.timestamp and a new empty file is created for storing the new log entries. The old log files are still accessible by direct access (FTP, SFTP or SSH) to var/log/amazonpayments folder on the server.
