# `kumo.on('get_queue_config', function(domain, tenant, campaign))`

!!! note
    This event handler is in flux and may change significantly

Not the final form of this API, but this is currently how
we retrieve configuration used for managing a queue.

```lua
kumo.on('get_queue_config', function(domain_name, tenant, campaign)
  return kumo.make_queue_config {
    max_retry_interval = '20 minutes',
  }
end)
```
