Are you looking to build an integration with Shopify? According to statistics, there are 2,859,828 live stores running on the Shopify platform in 2025.
Starting April 1, 2025, Shopify will require the use of the GraphQL API for new integrations. However, existing apps will continue using the REST API, as no changes are required for them. Moving forward, Shopify will focus on enhancing the GraphQL API.
If you prefer to stick with Shopify REST API and want to avoid switching to the GraphQL API, this article will guide you on how to continue using the REST API, despite the platform’s upcoming changes.
What is Shopify GraphQL API?
Shopify GraphQL API is a query language developed to make interaction with Shopify's platform more efficient. It enables developers to request some data in one query, preventing repeated API calls. This approach makes it possible to get only the necessary data faster, improving performance.
This type of API is especially useful when dealing with complex data structures. It helps developers retrieve multiple resources in one request, streamlining the integration process. Moreover, GraphQL grants developers more control over data when they receive it, making it more flexible when developing eCommerce apps or software.
What is Shopify REST API?
Shopify REST API is an interface that allows developers to interact with Shopify's platform using HTTP methods such as GET, POST, PUT, and DELETE. This API enables developers to retrieve and manipulate store data like customers, products, and orders by making requests to different endpoints.
With the REST API, developers can make standard requests, such as adding a product, adding an order, or getting customer information. Each request is made to a specified endpoint, and the data is returned in a structured format (usually JSON) that can easily be consumed by the application.
For most developers, particularly those building existing applications, the REST API is the easier option to connect with Shopify's platform.
For example, using the Shopify REST API products endpoint, developers can easily create, update, or fetch product information. Similarly, the Shopify REST API customer endpoint allows working with customer records. Developers can also check detailed documentation in the Shopify REST API docs to see all available endpoints and methods.
What are the main differences between Shopify REST API and GraphQL API?
The main differences between Shopify's API REST and GraphQL relate to data requests and the flexibility they provide.
1. Data Requests:
With the REST API, you need to make multiple requests to different endpoints to retrieve related data. For instance, in order to get the necessary information on products and their associated inventory, you would have to make different requests.
On the other hand, the GraphQL API allows developers to request all of the data they need in one request. Even when dealing with more complex data retrieval, this can lead to improved efficiency by making it possible to do so with a single request rather than multiple.
2. Response Flexibility:
The REST API provides the data in a fixed format. As a result, developer might get more data than they want, requiring additional processing or filtering of that data.
The GraphQL API allows you to specify the exact data you want, meaning you may not receive unnecessary data. It helps save on data transfer. However, this flexibility requires additional planning upfront in building queries.
3. Performance:
The REST API may be slower at handling multiple resources that relate to one another, since they generally need to be requested separately for different resources.
The GraphQL API allows multiple resources to be consolidated in a single request, which is more effective. However, this might not be needed for simpler use cases.
4. Utility and Compatibility:
REST APIs are standardized and relatively simple to implement for simple use cases, especially if it is already being used in your application.
GraphQL APIs allow for more customization but may require some knowledge to take full advantage of what it offers.
In summary, while GraphQL offers potential advantages related to efficiency and flexibility, REST APIs (compared to GraphQL) offer a stable, simpler option for many developers, especially for simpler integrations.
Shopify REST API Example
