What part of building CreatorCon C3 nearly broke me? The Replicate AI integration. Not because the API was bad, it’s excellent, but because I was juggling webhooks, HMAC validation, ServiceNow crypto APIs, and long-running AI processes for the first time… all with a two-minute test cycle.

In this article, I break down the end-to-end Replicate AI integration on ServiceNow: why multiple REST calls and webhooks are necessary, how to securely handle credentials, the importance of traceability in async workflows, and why I wish I had embraced Flow Designer from the start.

If you’re a developer tackling ServiceNow integrations, async orchestration, or Replicate AI, this deep dive will save you from my pillow-screaming moments.
