APP

Shopify App Development & API Integrations

When a storefront has to talk to a warehouse, a POS or a system nobody wants to replace, it needs an app behind it - with logs and alerts so failures surface first.

Process

  1. 01

    Draw the boundary

    Decide what stays in the theme and what moves behind an API.

  2. 02

    Model the data flow

    Which system owns which field, and how a failed sync recovers.

  3. 03

    Build against the API

    Typed clients, rate limits, and webhooks that expect duplicates.

  4. 04

    Instrument

    An integration that fails quietly is worse than none at all.
