If you paid by credit card, it is instantaneous in the vast majority of cases, and your candidate area will automatically display when a payment is recorded.

If you paid using cryptocurrency such as Bitcoin, it is usually just a matter of a few minutes before you receive payment confirmation, but sometimes it may take longer depending on whether the network is congested or not. In any case, you can also see on your side when the payment is still pending validation by the blockchain. Several confirmations from the Bitcoin network are always required for your payment to be validated.
