Magento 2 GraphQL vs REST API: Which One Should You Use in 2025?

Choosing between Magento 2 GraphQL vs REST API is one of the most important decisions for modern Magento developers. As Magento 2 moves further into the headless era, understanding how GraphQL and REST differ can help you optimize store performance, scalability, and integration workflows in 2025.

What Is REST API in Magento 2?

REST API (Representational State Transfer) is the traditional method of communicating between systems in Magento 2.
It allows external applications to read and write Magento data using HTTP requests.

Example REST API request:

GET /rest/V1/products?searchCriteria[pageSize]=5

Advantages of REST API

• ✅ Simple and well-documented
• ✅ Compatible with older systems (ERP, CRM)
• ✅ Easy to test using cURL or Postman

Limitations

• ❌ Multiple requests required to fetch related data
• ❌ Slower for complex data structures
• ❌ Over-fetching and under-fetching issues

REST APIs work well for backend system integrations but may slow down when powering modern headless storefronts.

What Is GraphQL in Magento 2?

GraphQL is a query language introduced in Magento 2.3 that gives developers precise control over the data they request.
Instead of multiple endpoints, GraphQL lets you send a single query to get exactly what you need.

Example GraphQL query:

{
  products(filter: {sku: {eq: "24-MB01"}}) {
    items {
      name
      price {
        regularPrice {
          amount {
            value
            currency
          }
        }
      }
    }
  }
}

Advantages of GraphQL

• ⚡ Faster performance — only retrieves requested fields
• 💡 Ideal for PWA and headless Magento 2 stores
• 🔁 Reduces network load by combining multiple calls into one
• 🎯 Flexible and frontend-friendly

Limitations

• ❌ Requires schema understanding
• ❌ Caching can be more complex
• ❌ Slightly higher learning curve for new developers

For developers working with Magento 2 PWA Studio, GraphQL is now the default API layer.

Magento 2 GraphQL vs REST API: Key Differences

GraphQL isn’t replacing REST entirely — instead, it complements REST by providing a more modern, scalable approach to frontend communication.

When to Use Each API in Magento 2

Use REST API When:

• You need to connect Magento with legacy systems (ERP, CRM).
• You are working with mobile apps or backend scripts.
• The project requires stable, versioned endpoints.

Use GraphQL When:

• You’re building a PWA, Vue, or React frontend.
• You need faster, dynamic, real-time data fetching.
• Your store architecture follows a headless or microservice model.

Conclusion

Both GraphQL and REST API are essential to the Magento 2 ecosystem — but for 2025 and beyond, GraphQL stands out as the preferred technology for headless, PWA, and modern frontend architectures.

If you’re still using REST exclusively, consider gradually migrating key parts of your store to GraphQL for better speed and flexibility.
