How long are logs kept? We want to report an issue from last month.

Detailed logs are retained for roughly two weeks. After that a specific case usually cannot be traced back through the logs. Report issues while they are recent, and if something recurs, report the new occurrence immediately rather than referring back to the old one.

Responses on API-calls is not logged from Brink side. Brink is expecting that the receiver is logging this on their end.
