# Retrieve logs of a specific connection

`GET /api/2/connections/{connectionId}/logs`

Returns the logs of the connection identified by the `connectionId` path parameter.
**Before** log entries are generated and returned, logging needs be enabled with the `command`
`connectivity.commands:enableConnectionLogs`. When creating or opening an connection the logging is enabled per
default. This allows to log possible errors on connection establishing.
