Shopify API Showdown: REST vs. GraphQL for Your Private Apps
Understanding the Shopify API Landscape: REST vs. GraphQL
So, you're building a private app for your Shopify store and are wondering which API – REST or GraphQL – is the better choice? It's a common question, and recently AlessandroGnola brought it up in the Shopify Community, sparking a helpful discussion. Let's break down the key points and figure out the best path forward for you.
AlessandroGnola, like many of us, has been working with REST APIs and JSON for private apps and noticed the growing buzz around GraphQL. His main question was, "If GraphQL is recommended, why does the REST API still exist?" He also pointed out the convenience of REST APIs, especially when dealing with suppliers.
It's a valid point. REST APIs are familiar and widely used. AlessandroGnola even mentioned that other platforms like WooCommerce, PrestaShop, and Magento rely on REST. So, why the shift?
The Current State of Affairs: REST for Now, GraphQL for the Future
The good news is, for private apps, you can still use REST APIs for now. Tim_1 clarified this in the community thread: "GraphQL is required for public apps; for private apps you can keep using REST for now."
That being said, Tim_1 also dropped a crucial piece of advice: "Just be ready to migrate when they announce the REST sunset. 
"
So, while REST is still an option, it's wise to consider the long-term implications. Shopify is clearly pushing towards GraphQL, and eventually, REST will likely be phased out. Think of it as a heads-up to start preparing for the future.
Why GraphQL?
You might be wondering, why the move to GraphQL in the first place? Here's the gist:
- Efficiency: GraphQL allows you to request exactly the data you need, nothing more. This reduces the amount of data transferred, leading to faster and more efficient apps.
- Flexibility: With REST, you're often stuck with the data structures defined by the API. GraphQL gives you more control over the shape of the data you receive.
- Strong Typing: GraphQL has a strong type system, which helps catch errors early and makes your code more maintainable.
What About My Specific Needs?
AlessandroGnola mentioned needing to export orders, create discounts, and update stock. All of these tasks can be accomplished with both REST and GraphQL. The choice really comes down to your comfort level, long-term strategy, and the complexity of your app.
Making the Decision: REST or GraphQL for Your Shopify App
Here's a breakdown to help you decide:
- Stick with REST if:
- You're already familiar with REST and have existing code.
- You need to get something up and running quickly and don't have time to learn GraphQL.
- Your app is relatively simple and doesn't require the advanced features of GraphQL.
- Consider GraphQL if:
- You're starting a new project and want to future-proof your app.
- You need to optimize performance and reduce data transfer.
- You want more control over the data you receive from the API.
- You plan to develop public apps in the future (GraphQL is required).
Preparing for the Future: A Gradual Transition
Even if you choose to stick with REST for now, it's a good idea to start learning GraphQL. You can begin by experimenting with the Shopify GraphQL API in your spare time. There are plenty of resources available online, including the official Shopify documentation. Also, keep an eye on Shopify's announcements regarding the future of the REST API. Tim_1's comment about being ready to migrate is definitely something to keep in mind!
Ultimately, the best choice depends on your specific circumstances. Weigh the pros and cons of each API, consider your long-term goals, and don't be afraid to experiment. And remember, the Shopify Community is a great place to ask questions and get help from other developers. Thanks to AlessandroGnola for starting the conversation and to Tim_1 for providing valuable insights!
