You can review incoming payment before it is completed and decide whether you want to approve or reject it.

Review Decission	Description
`APPROVE`	The payment has been created and after approval will go to COMPLETED status
`REJECT`	The payment has been created and after rejection will go to REJECTED status. No return will be made automatically. We suggest to use it only if return cannot be made
`REJECT_AND_RETURN`	The payment has been created and after rejection will go to REJECTED status. Automatically a return will be made to the original Payer. The payment will be refunded and its status will be updated to 'RETURNED'.

To use the Reject and Return option, you'll need to provide payee information. For more details, check here
