Create Shop Integration

Learn how to create custom shop integrations

Overview

Shops are the places where your customers are already placing orders like marketplaces or e-commerce platforms. Openship has a built-in integration for Shopify so new integrations can be built by following the same pattern.

Shopify Shop Integration Reference

The Shopify shop integration (/features/integrations/shop/shopify.ts) demonstrates all required functions for a complete shop integration. This guide will explain how each function works and how to implement it for your own shop integration. Each function below has 3 parts, what Openship sends to the function, how the function works, and what Openship expects to be returned.

OAuth Integration

If you have a Shopify app (or app on any platform), you can implement OAuth functions to allow users to install your app directly instead of manually retrieving access tokens. This provides a smoother user experience where users can authorize your integration through the standard app installation flow.

OAuth Authorization

Purpose: Openship uses this function to generate secure OAuth authorization URLs that allow users to safely connect their shop platforms to Openship without sharing sensitive credentials

Request Body:

PropTypeDefault
platform{ domain: string; accessToken: string }-
callbackUrlstring-

Response Format:

FieldTypeDescription

  const shopifyAuthUrl = `https://${platform.domain}/admin/oauth/authorize?client_id=${process.env.SHOPIFY_APP_KEY}&scope=${scopes}&redirect_uri=${callbackUrl}&state=${Math.random().toString(36).substring(7)}`;
  
  return { authUrl: shopifyAuthUrl };
}

OAuth Token Exchange

Purpose: Openship uses this function to complete the OAuth flow by exchanging temporary authorization codes for permanent access tokens, establishing a secure connection to the user's shop platform

Request Body:

PropTypeDefault
platform{ domain: string; accessToken: string }-
codestring-
shopstring-
statestring-

Response Format:

FieldTypeDescription
accessTokenstringOAuth access token for API authentication
domainstringShop domain for API requests
export async function oAuthCallbackFunction({
  platform,
  code,
  shop,
  state,
}: {
  platform: { domain: string; accessToken: string }; 
  code: string;
  shop: string;
  state: string;

  const response = await fetch(tokenUrl, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      client_id: process.env.SHOPIFY_APP_KEY,
      client_secret: process.env.SHOPIFY_APP_SECRET,
      code,
    }),
  });

  if (!response.ok) {
    throw new Error("Failed to exchange OAuth code for access token");
  }

  const { access_token } = await response.json();
  
  return { 
    accessToken: access_token,
    domain: shop,
  };
}

Webhook Event Handlers

Adding Your Shop Integration to Openship

Once you've implemented your shop integration functions, you need to create a shop platform in Openship. Here's exactly what you'll see in the Openship interface:

1. Navigate to Shop Platforms

In Openship, go to the Shops page where you'll see the platform management interface:

Platforms

2. Create Shop Platform Dialog

Click the "Create platform to get started" button to open the platform creation dialog:

Create Shop Platform

Create a platform based on an existing template

3. Platform Template Selection

When you click the dropdown, you'll see the available templates:

Templates
Shopify
Bigcommerce
Woocommerce
Demo
Medusa (soon)
Magento (soon)
Stripe (soon)
Custom
Start from scratch...

4. For Built-in Integration - Select Template

If you created a built-in integration file (e.g., myplatform.ts in /features/integrations/shop/), you would:

  1. Add your template to the shopAdapters list in CreatePlatform.tsx:
const shopAdapters = {
  shopify: "shopify",
  bigcommerce: "bigcommerce", 
  woocommerce: "woocommerce",
  demo: "demo", // Demo integration for testing
  myplatform: "myplatform", // Add your integration here
  // ...
};
  1. Select your template from the dropdown
  2. Fill in the basic fields: Name, App Key, App Secret (if needed)

5. For Custom HTTP Integration - Select "Start from scratch..."

If you're using HTTP endpoints, select "Start from scratch..." to see all the function fields:

When you select "Start from scratch...", you'll see form fields where you can enter your custom HTTP endpoints for each function.

6. After Creating Platform

Once you create the platform, it appears in the platforms list:

Platforms

MY PLATFORM

Actions

7. Create Shops Using Your Platform

Now you can click "Create Shop" to create individual shop instances that use your platform template. Each shop will use the same integration logic but with different credentials (domain, access tokens, etc.).

The platform system ensures your integration functions are reusable across multiple shop instances while maintaining clean separation between template logic and instance-specific configurations.
