Why it matters
Why Shopify apps need platform-native discipline
API version sunsets and scope changes break brittle apps. Without monitoring, merchants churn silently.
Faster App Store review
Checklists for screenshots, privacy policy, and functional review.
Merchant-trust UX
Loading states, error recovery, and clear permission prompts.
Operational reliability
Queues, retries, and dead-letter handling for webhooks.
Monetization clarity
Pricing models that match Shopify billing APIs.
Security posture
Least-privilege scopes, encrypted storage patterns, and audit logs.

Public App Store vs custom app?
We help choose based on distribution, revenue share, and review overhead—sometimes both phases.

How do you handle API versioning?
Quarterly upgrade windows, automated tests against beta APIs, and changelogs for your team.
