- Authorize: Payments are automatically authorized, but manual capture is required.
- Don’t authorize: Manual authorization and capture are required. Useful for pre-orders.
Under Authorization processing mode, choose how authorizations will be handled:
- Asynchronous: An initial synchronous authorization attempt is made, and if it fails, the order is placed On Hold and asynchronous attempts are triggered for the next 24 hours. This option maximizes conversions and is highly recommended for merchants selling expensive items. (Only available for Authorize or Don't authorize mode)
