# Combo Approval Event

> PositionManager approval events relevant to combo settlement and auto-redemption.

Emitted for approvals that affect combo settlement or redeemability.

<Note>
  The default combo stream does not include approvals. Request `combo_approval` explicitly if you need approval monitoring. Collateral ERC20 allowance approvals are intentionally not part of the default customer stream.
</Note>
