Use this Method in the sandbox to simulate the completion or cancellation of a Payin , i.e., funds deposited, charged to the customer, or cancellation of the Payin.
The Payin must be in a PENDING status to complete or cancel it. Upon successful execution, the Payin status updates to COMPLETED or CANCELLED. If the Payin is not in a PENDING status or if you attempt to complete an already completed or cancelled Payin, a 406 error will be returned.
