Begin Shopify app development with the merchant action and the surface or system responsible for it. A display change may belong in a theme; administrative work, event processing or system integration may justify an app. Decide whether it serves one organization or public distribution before designing permissions, hosting and operations.
Map requirements to interface, data and distribution
Identify users, inputs, objects read or changed, outcomes and error feedback. Distinguish extensions within Shopify from the app's backend, and identify who installs it. The official building documentation explains components and distribution routes. Choose the form for the requirement instead of adding merchant steps to fit a framework.
A data-editing feature needs clear fields, operators and failure feedback. An order-support feature needs initiating states and excluded orders. For automated delivery, continue with “Shopify Plus order automation: states and intervention” to settle the business rules before implementing actions.
Prototype with a limited data scope
Use current tooling and a dev store through the scaffolding tutorial. Request the permissions the feature requires and handle absent or changed access and deleted objects explicitly. Successful reads also need field interpretation, pagination and missing-data checks so the app does not work only on complete sample records.
For webhooks, verify signatures and repeated processing against delivery verification. Keep secrets out of browser pages and avoid including full orders or customer records in public errors.
Deliver the release and operating process together
Record configuration, permissions, data structures and compatible API versions for each release. Assign ownership for code, extension configuration and the self-hosted backend. Check dependencies, coexistence of old tasks with new code, and the version to restore after failure.
Handover should cover installation, configuration, monitoring, retries, intervention, export and what happens on removal. Use “Shopify Partner developer practice and handover” to keep reproducible evidence for whoever maintains the project next.
FAQ
Does every customization require an app?
Check themes, existing features and apps first. Choose a custom app when the interface, data operation or integration responsibility needs it.
Is a working dev-store prototype ready to release?
Also inspect actual permissions, unusual data, repeated events, dependencies, monitoring and takeover. Public distribution has its own current review requirements.
What should removal instructions explain?
Which processes stop, how outstanding work ends, how data is retained or handled, and how the merchant resumes the original workflow.
