How long are logs retained

API call logs are retained for 60 days before being automatically removed from the system, necessitating users to make regular backups to preserve records of their API activity. This can be achieved through the Unified.to Admin API, with an example provided for users utilizing the Node SDK, which involves the listUnifiedApicalls() method in the '@unified-api/typescript-sdk'. This proactive approach ensures that all API call logs are retained beyond the 60-day window set by the system.
