6. Handle a charge, top-up or transfer callback

Paga sends this to your server. You don’t call it; build an endpoint at your callback URL that accepts it.

Sent when a charge (SUBSIDIARY_ACCOUNT_CHARGE_COMPLETE), top-up (SUBSIDIARY_ACCOUNT_TOP_UP_COMPLETE) or transfer (SUBSIDIARY_ACCOUNT_TRANSFER_COMPLETE, source account only) completes.

Hash: externalReferenceNumber + transactionDate + amount + accountNumber + hashKey. amount is a formatted string with commas, such as 1,000.00; don’t convert it to a number.
