The timers are in the PusherChannelsWebhook_API module that can be configured and scheduled per tenant to run.

The "Timer_TrimWebhookQueue" timer is set to run every hour. The TrimWebhookQueue_EnableTrim site property controls the timer.
The "Timer_TrimWebhookQueueErrors" timer is set to run every hour. The TrimWebhookQueueErrors_EnableTrim site property controls the timer.
