External APIs still work via normal HTTP.\n\n**Q: How do I migrate from existing setup?**\nA: Blue-green deployment: Deploy alongside existing, switch traffic gradually.\n\n**Q: Is there a cost cap?**\nA: Yes, Cloudflare Workers have predictable pricing and optional caps.\n\n### Support Resources\n- Cloudflare Workers Docs: https://developers.cloudflare.com/workers/\n- Durable Objects Guide: https://developers.cloudflare.com/workers/runtime-apis/durable-objects/\n- Queues Documentation: https://developers.cloudflare.com/queues/\n- Discord Community: https://discord.gg/cloudflaredev\n\n---\n\n## Conclusion\n\nThis Cloudflare-native optimization reduces external API calls by 99%, improves latency by 80%, and cuts costs by 70% while maintaining full compatibility with existing IntegrateWise services.\n\n**Ready for production deployment.**\n"}
