How will I know if the cash sent has been accepted by the other person?

Hi there ulises263,

We have information for your question about sending Apple Cash payments and how to determine if they've accepted it. We'll use information from this resource: Send and receive money with Apple Cash - Apple Support

Once you've sent Apple Cash:

1. Open the Messages app, then open the conversation.
2. Tap the payment.
3. Under Latest Transactions, tap the payment, then tap it again.
4. If you do not see an option to Cancel Payment, the other person has accepted the payment.

Keep in mind they will have up to 7 days to accept the Apple Cash.

All the best.
