Hi @Maria1522. Just to make sure I am following your post, you sent a request for money via the reservation, right? The message is sent to the guest and the guest then approves it. Once approved the additional funds will be collected from the guest credit card or payment method. If the request comes before the check in, you will be paid along with the nightly fee. If the request is after your nightly rate payout, it will come as a separate payout.
When I have used this function I received an email confirmation of the guest approval. You did not get this? Perhaps the guest does not know to approve the extra charge? Send a message to the guest to clarify the process. Hope this helps.
