The most important technical difference between Paystack and Monnify for bank-transfer-heavy products is how virtual accounts work:

Paystack virtual accounts:

• Created per transaction — the customer gets a new account number for each payment
• Time-limited — account expires after the transaction completes or times out
• Better for one-time checkout where you initiate the amount

Monnify static virtual accounts:

• Each customer can be assigned a permanent virtual account number
• Customer transfers any amount to their personal virtual account at any time
• Monnify fires a webhook on each transfer, regardless of amount
• Better for wallets, savings products, and top-up flows

// Monnify: create a reserved account for a customer
var response = await fetch('https://api.monnify.com/api/v2/bank-transfer/reserved-accounts', {
  method: 'POST',
  headers: {
    Authorization: 'Bearer ' + monnifyToken,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    accountReference: 'customer_' + customerId,
    accountName: customerName,
    currencyCode: 'NGN',
    contractCode: process.env.MONNIFY_CONTRACT_CODE,
    customerEmail: email,
    customerName: customerName,
    getAllAvailableBanks: true, // customer can pay via any bank
  }),
});
// Monnify returns a set of virtual account numbers (one per bank)
// Customer uses any to transfer; webhook fires on receipt

For a savings or wallet product where customers top up their account by bank transfer at will, Monnify's reserved accounts are architecturally cleaner than Paystack's per-transaction approach.
