# Activity completion
> Enable activity completion for BigBlueButton in Moodle using live event callbacks from the BigBlueButton server.
BigBlueButton can participate in Moodle activity completion.
## Requirement
Activity completion depends on the BigBlueButton server sending live events back to Moodle, and on Moodle being configured to receive them.
## Enable it
1. Log in as an administrator.
2. Open the BigBlueButton plugin settings.
3. Enable **Register live events** or the equivalent site option.
4. Save the setting.
## Test it
If your Moodle server is behind a restrictive firewall, the callback might not reach Moodle correctly.
A simple test is:
1. enable live events
2. create a test recording
3. set a very low attendance threshold
4. confirm that the completion signal is received and processed
