Sell on Daraz with automatic inventory and order sync

// Nafaa handles the Daraz OAuth flow automatically
// This is what happens behind the scenes:

async function handleDarazCallback(code, state) {
  const tokens = await fetch('https://auth.daraz.pk/oauth/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      grant_type: 'authorization_code',
      code,
      redirect_uri: 'https://app.nafaa.pk/oauth/daraz/callback',
    }),
  }).then(r => r.json());

  // Store encrypted tokens in Nafaa tenant config
  await nafaa.integrations.daraz.save({
    accessToken: tokens.access_token,
    refreshToken: tokens.refresh_token,
    sellerId: tokens.seller_id,
    expiresAt: Date.now() + tokens.expires_in * 1000,
  });

  // Trigger initial product and order sync
  await nafaa.integrations.daraz.sync({ full: true });
