_[API Logs](🔗) are transaction logs that enable you to view your API transaction history and debug API errors with no setup required. They show the most accurate representation of what Circle received and sent. When you send an API request, Circle stores it along with its associated response. On the API logs page, you can view these API logs for seven days after the request is sent and filter them to find the specific request you are looking for. You can use the API logs to debug API errors without having to log out of your system._
To access the logs, go to Circle Sandbox or Circle Account and click on Developer Tab --> Logs.
