What Is Shopify Third Party Integration?

The Complete Guide to Shopify Third Party Integration

So what exactly is Shopify third party integration? In simple terms, it means connecting your Shopify store to external apps and services to enhance functionality. Through third-party app integration, you enhance the customer experience.

There are a few ways to integrate third party apps with your Shopify store:

  • Shopify App Store: The easiest method is to install an app directly from the Shopify App Store. There are thousands of free and paid apps for everything. Upon installation, the app seamlessly integrates with your store.
  • Shopify API: For more advanced needs, utilize the Shopify API for custom integration, accessing store resources like products, orders, and customers to manipulate or extract data.
  • External services: You can also integrate external services that aren't listed in the App Store like payment gateways or fulfillment companies. A developer can use the Shopify API to build an integration to connect your store to these external services.

Integrating third-party apps to your Shopify store enhances functionality and user experience. While the App Store makes it easy to get started, for advanced integrations with external services, you'll have to hire an expert Shopify developer. 

The Benefits of Shopify Integration Services

Integrating Shopify with third-party apps boosts business growth effectively. Here are some of the major benefits of Shopify integration services:

  • Increased sales: By integrating apps for live chat, email marketing, loyalty programs, etc., you make it easier for customers to engage with your brand and buy from you. Studies show that engaged customers spend 60% more per purchase.
  • Improved efficiency: Integrations automate time-consuming manual processes so you can focus on growing your business. Sync your orders, fulfillments, and inventory levels across channels with the click of a button.
  • Deeper insights: Integrated analytics tools give you a holistic view of your key metrics and customer behaviour across platforms. See your top products, best performing marketing campaigns, busiest shopping hours, and more.
  • Better customer experience: A seamless purchasing experience is essential to customer satisfaction and loyalty. Integrations enable conveniences like save payment info, auto shipping, and push notifications about order updates or special offers.
  • Future-proofing your business: The ecommerce landscape is always changing. Integrations allow you to easily add new channels, features, and capabilities to your store so you can adapt to trends and stay ahead of competitors.

The options for integrating with Shopify are nearly endless. Whether you want to streamline fulfillment, engage customers, simplify accounting, or all of the above, integration services can help take your Shopify store to the next level.

Top Shopify Integration Options

The Complete Guide to Shopify Third Party Integration

When integrating with Shopify, you have several excellent third-party options to choose from. Here are some of the top Shopify integration services to consider:

Custom App Development

Shopify’s API and SDKs make Shopify app development accessible whether you want to build something simple or sophisticated. You’ll have full control and flexibility over the functionality and user experience. 


Zapier is an extremely popular integration platform that connects Shopify with over 1,500 other business apps. Their user-friendly interface automates workflows between Shopify and various services such as email marketing, accounting, shipping, etc.


Webhooks enable real-time data transmission from Shopify to other apps and services easily. When certain events happen in your store, like orders being placed or products being updated, Shopify will send a webhook request to a URL of your choice. 

API Integrations

For robust integrations, the Shopify API provides full access to store data and resources. API integrations typically require an app to be built to authenticate with the API and handle data exchange.

The key is choosing an integration method that matches your technical skills, budget, and business needs. With the right approach, you can build a seamless Shopify experience for your customers and unlock powerful new capabilities for your store.

How to Choose a Shopify Integration Partner

Choosing a Shopify integration partner is an important decision. The partner you select will be responsible for connecting your Shopify store to third-party software and services to enhance your business operations. 

Here are some tips to help you find the right Shopify integration partner:

Check their experience

Look for a partner with extensive experience developing Shopify integrations and apps. They should have a proven track record of successful integration projects. Ask about the types of integrations they’ve built and check their app store profile and reviews. 

Review their services

Find a partner that offers the services you need. This could include:

  • Shopify API integration development
  • Custom app development
  • Third-party software integration (ERP, CRM, etc.)
  • Ongoing support and maintenance

A full-service partner can handle all your needs, from initial integration through launch and beyond.

Ask about their process

An ideal partner will have a structured integration process to ensure a smooth project experience. This includes steps like:

  1. Discovery call to determine requirements
  2. Solution design and technical specifications
  3. Development and testing
  4. App store submission and review
  5. Launch and on boarding support

Check references and reviews

Don’t hesitate to ask the partner for references from past clients. Contact the references to get their feedback. You should also read online reviews from the partner’s other clients to determine their overall satisfaction and experience.

FAQs About Shopify API Integration Development

Shopify's API and app ecosystem offer a lot of opportunity. However, you probably have some questions about getting started. Here are some of the most frequently asked questions about Shopify API integration development.

What programming languages can I use?

Shopify's API supports integration in many languages, including:

  • Ruby
  • PHP
  • Java
  • Python
  • Node.js

So you can choose a language you're comfortable with to build your app.

Do I need a Shopify partner account?

To access the Shopify API and build an app, you'll need a Shopify partner account. This is free to set up and gives you access to the Partner Dashboard, API documentation, and app store.

What is the app development cost?

The cost to build a Shopify app can vary greatly depending on the complexity. Simple apps can be completed in a few hours, while complex ones may require weeks or months. The total cost will depend on the number of hours required for your specific app.

Do I need to know Liquid, the Shopify Template Language?

Knowing Liquid, Shopify’s template language, is very useful for building Shopify apps and integrations. Liquid allows you to customize Shopify themes and access data from products, orders, customers, etc.
