New in version 0.32.

The kickbacks: section of your machine config is used to define kickback mechanisms which are a type of autofire coil that kicks the ball back into play, typically located in an outlane.

Example:

#config_version=4

coils:
  kickback_coil:
    number:
    pulse_ms: 100

switches:
  s_kickback:
    number:

kickbacks:
  kickback_test:
    coil: kickback_coil
    switch: s_kickback
    enable_events: kickback_enable
    disable_events: kickback_kickback_test_fired

ball_saves:
  kickback_save:
    balls_to_save: 1
    active_time: 5s
    enable_events: kickback_kickback_test_fired

Since kickbacks are a type of autofire coil, they have the same settings as autofire_coils:. See that documentation for a list of all the settings and options.
