Role Based Access for Payment Operations Teams

Role	Can Do	Cannot Do
Developer	Deploy code, read logs, use test API keys, rotate keys in staging	Initiate production transfers, access live customer PII outside audit context
Finance / Ops	View transaction history, download CSV reports, view refund status	Trigger refunds independently, initiate transfers, modify API keys
Transfer Approver	Approve transfers initiated by the system, view transfer queue	Approve their own transfers, bypass dual-approval on amounts above threshold
Auditor	Read all payment records, download audit logs, view access history	Modify any records, trigger any API calls
Admin	All of the above, plus manage team members and API key rotation	Should still require dual approval for large transfers

// middleware/requirePaymentRole.js
function requirePaymentRole(...allowedRoles) {
  return (req, res, next) => {
    var userRole = req.user?.payment_role; // Set from your session/JWT
    if (!userRole || !allowedRoles.includes(userRole)) {
      return res.status(403).json({ error: 'Insufficient permissions for this payment operation' });
    }
    next();
  };
}

// Applying roles to payment routes
// Transaction list — Finance and above can see
app.get('/api/transactions', requirePaymentRole('finance', 'transfer_approver', 'admin', 'auditor'), listTransactions);

// Initiate transfer — system only (no human-facing endpoint), or admin with audit log
app.post('/api/transfers/initiate', requirePaymentRole('admin'), async (req, res) => {
  var { amount, recipient } = req.body;
  // Log the initiating user for audit trail
  await db.audit_log.create({
    user_id: req.user.id,
    action: 'transfer_initiated',
    amount,
    recipient,
    timestamp: new Date(),
  });
  // Proceed with transfer...
});

// Approve transfer — transfer_approver role, but not the same user who initiated
app.post('/api/transfers/:id/approve', requirePaymentRole('transfer_approver', 'admin'), async (req, res) => {
  var transfer = await db.transfers.findById(req.params.id);
  if (transfer.initiated_by === req.user.id) {
    return res.status(403).json({ error: 'Cannot approve your own transfer' });
  }
  // Proceed with approval...
});

When a team member with payment access leaves:

1. Remove their Paystack dashboard access (Settings → Team in Paystack dashboard)
2. Rotate the live secret key if the departing person had direct access to it
3. Remove their role from your application's payment role table
4. Audit their recent activity: check audit_log for transfers or data exports in the last 30 days
5. Revoke any personal API tokens or service account credentials they managed
6. Update your password manager / secrets vault access list
