I sent a payment (charge) request to my customer, but it still shows as pending.
Customers have up to 48 hours to approve a payment request. They can easily do this by clicking the link they received via text or email, which will take them to their consumer portal where they can review and approve the request.
If needed, you can send a new request at any time. When you do, the original request will be marked as 'expired' to prevent accidental double approvals.
