Best Practices

  1. Use descriptive codes - Make codes easy to remember and associate with campaigns
  2. Track usage - Monitor usedCount to measure campaign effectiveness
  3. Use categories - Group codes by campaign, partner tier, or time period
  4. Validate before display - Check code validity before showing to users
  5. Handle pagination - Use cursor for large code lists
