Stripe Idempotency Key Not Implemented
Same charge processes multiple times if request retries. Customers are charged twice for one payment.
Idempotency keys prevent duplicate processing on network retries.
Common Causes
- No Idempotency-Key header sent to Stripe
- Using random key instead of deterministic
- Not reusing key on retries
- Stripe idempotency not enabled in SDK
How to Fix It
Generate idempotency key from order ID (deterministic). Send with every Stripe request: RequestOptions.setIdempotencyKey(). For retry logic, reuse same key. Store processed keys with results to detect duplicates. Stripe repeats response for identical key within 24 hours.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Use order ID or UUID. Important: same operation = same key every time
