APIEase + Shopify Flow Integration Architecture

APIEase and Shopify Flow work best when used together — each playing a distinct role. This page explains the architecture and design philosophy for integrating APIEase with Flow, helping you decide how to structure automations that connect your store to external APIs.

🧠 Core Philosophy

• Shopify Flow is your logic engine
  It handles conditional logic, decision trees, branching, and native Shopify actions.

• APIEase is your API execution layer
  It securely performs API calls (including ones requiring credentials), schedules tasks, handles responses, and triggers Shopify Flow when needed.

🧩 APIEase as the Starting Point

APIEase is usually the first step in your automation. Here's why:

• You need to call external APIs
  Most real-world integrations require sending or retrieving data from third-party systems like ERPs, warehouses, AI services, CRMs, etc.

• You need credentials
  Shopify Flow isn’t designed to store or manage confidential API credentials. APIEase handles that securely.

• You need the API response
  Shopify Flow's native Send HTTP Request action doesn't return a response to Flow. APIEase captures API responses and passes them into Flow workflows for further processing.

• You want flexible triggering
  APIEase can initiate flows on a schedule, from a webhook, or manually via a storefront or admin UI.

🔄 Example Flow Architecture

1. Start in APIEase
   An APIEase request fetches or receives data from an external system (e.g., a product feed, shipping update, webhook payload, etc.).

2. Chain a Flow Request
   Use a chained request to send the response into a Shopify Flow via the APIEase Flow Trigger.

3. Use Flow Logic
   Inside Flow, run conditional logic, evaluate the data, or transform it using a Run Code action.

4. Make a Follow-up API Call (optional)
   If needed, chain a third APIEase request to make another API call using the output from Flow — for example, to update an external system based on Flow decisions.

⚠️ A Note on Calling Shopify APIs

Shopify Flow includes a Send Admin API Request action that can directly call Shopify’s GraphQL Admin API. In cases where the API call is simple and requires no credentials, this action may be sufficient.

However, if the API request:

• Requires credentials,

• Involves data returned from another API,

• Or is part of a larger chained workflow,

...then APIEase is often the better place to handle that call.

🛠 Common Use Cases

• Importing products and inventory from external systems

• Pushing Shopify order data to an ERP or 3PL

• Syncing inventory levels with a warehouse

• Calling third-party AI or recommendation engines

• Responding to webhook events with chained logic and outbound API calls

• Building full backend workflows without writing a custom app

🧭 Summary

Use Shopify Flow for logic, and APIEase for calling APIs and handling data. If your workflow involves external services, data transformations, or credentialed API requests, APIEase should be the first or last step in your chain — with Flow in the middle as your logic engine.
