REST vs GraphQL: Which Should You Use?

GraphQL isn't better than REST. REST isn't better than GraphQL. They solve different problems, and the "right" choice depends entirely on what you're building.

The debates online are mostly ideology. What actually matters is matching the tool to your situation.

The Decision Framework

Before diving into trade-offs, here's the shortest possible answer:

Your Situation Use This
Single API calls, simple integrations REST
Multiple APIs per page load, complex UIs GraphQL
Building automations (Zapier, Make) REST
Mobile app where network latency matters GraphQL
Team doesn't know GraphQL REST
Need only specific fields from large responses GraphQL
Prototyping, moving fast REST

If you're not sure, start with REST. It's simpler, and you can add GraphQL later for specific use cases that need it.

What Each Actually Does

REST is resource-based. Each endpoint returns a complete resource. You call /users/123 and get the full user object. You call /orders and get all orders. Simple, predictable, stateless.

GraphQL is query-based. You write a query specifying exactly what you want, and you get exactly that—nothing more, nothing less. Multiple resources can come back in a single request.

Neither approach is inherently faster or more "modern." They're different mental models for organizing API access.

When REST Wins

Simplicity

REST is HTTP. Everyone knows HTTP. Your junior dev knows HTTP. The contractor you just hired knows HTTP. The curl examples in documentation just work.

GraphQL requires learning a query language, understanding schemas, and often using specialized client libraries. That's not prohibitive, but it's overhead.

Caching

REST endpoints can be cached by URL. Any HTTP cache—CDN, browser, proxy—understands how to cache GET /api/users/123. You get caching infrastructure for free.

GraphQL uses POST requests with query bodies. Standard HTTP caching doesn't work. You need specialized solutions like persisted queries or normalized client caches (Apollo, urql). More power, more complexity.

Debugging

When a REST call fails, you know exactly which resource failed. The URL tells you everything.

When a GraphQL query fails, you might get partial success—some fields resolve, others don't. Your error handling needs to account for this. It's more powerful (you still get the data that worked) but also more complex.

Tooling and Integration

Every tool supports REST. Postman, curl, Zapier, Make, Power Automate, webhook systems—they all speak REST natively.

GraphQL support is growing but not universal. If you're building integrations with no-code tools or need broad compatibility, REST is safer.

When GraphQL Wins

Multiple Resources Per Request

This is GraphQL's killer feature. Instead of calling three endpoints and stitching responses together, you write one query that returns exactly what you need.

For a dashboard showing user info, recent orders, and notifications, REST means three round trips. GraphQL means one.

On fast connections, this difference is minor. On mobile networks or high-latency connections, it's significant. Fewer round trips = faster perceived performance.

Precise Data Fetching

REST endpoints return complete resources. If you only need a user's name and email, you still get their address, preferences, metadata, and everything else.

GraphQL lets you request exactly the fields you need. For bandwidth-sensitive applications (mobile, IoT, high-volume), this matters.

Evolving APIs Without Versioning

With REST, changing a response structure often means versioning (/v1/users, /v2/users). Old clients break if you remove fields.

GraphQL clients specify what they need. You can add fields freely, and deprecate old ones gradually. Clients only break if they ask for something removed—and you can track exactly who's using what.

Complex, Nested Data

When your data is deeply nested—users with orders with line items with products—REST requires either multiple calls or custom "include" parameters.

GraphQL handles nesting naturally. You describe the shape you want, traversing relationships in a single query.

The Trade-Off Table

Aspect REST GraphQL
Learning curve Low Medium
HTTP caching Native Requires work
Tooling support Universal Growing
Error handling Simple Partial success possible
Network efficiency Multiple calls Single call, precise fields
Mobile performance Good Better (fewer round trips)
Schema/type safety Optional Built-in
Debugging Straightforward More nuanced

The Cost Question

On APIVerve, GraphQL has a pricing difference worth knowing:

  • REST calls: Each API costs its normal credit amount
  • GraphQL queries: Each API in your query costs its credit, plus 1 credit for orchestration

So a GraphQL query hitting 3 APIs costs 4 credits, while 3 REST calls cost 3 credits.

You're paying for the convenience of single-request aggregation. Whether that's worth it depends on what you value—lower latency or lower cost.

The Hybrid Approach

You don't have to pick one for everything. Many applications use both:

  • REST for simple, single-resource operations
  • REST for webhook integrations and third-party tools
  • GraphQL for complex dashboard pages
  • GraphQL for mobile clients where round trips hurt

This isn't indecision—it's pragmatism. Use the right tool for each situation.

Common Mistakes

Switching for the Wrong Reasons

"GraphQL is newer" isn't a reason. "Netflix uses it" isn't a reason. "It feels more sophisticated" definitely isn't a reason.

Switch when you have a concrete problem GraphQL solves: too many round trips, too much overfetching, too much complexity managing multiple API calls.

Over-Engineering from Day One

Starting a new project? Use REST. Get something working. Ship it.

If you later discover that your dashboard makes 8 API calls per page load and performance suffers, then consider GraphQL for that specific page. Don't architect for problems you don't have yet.

Ignoring Your Team

If your team knows REST and doesn't know GraphQL, factor in the learning curve. The best technology choice is one your team can execute well.

Quick Reference

APIVerve REST:

GET https://api.apiverve.com/v1/randomquote
Header: x-api-key: YOUR_KEY
Enter fullscreen mode Exit fullscreen mode

APIVerve GraphQL:

POST https://api.apiverve.com/v1/graphql
Header: x-api-key: YOUR_KEY
Body: {"query": "{ randomquote { quote author } }"}
Enter fullscreen mode Exit fullscreen mode

Same API key. Same underlying APIs. Different access patterns.


The right answer isn't REST or GraphQL. It's understanding what each does well and choosing based on your actual constraints—team expertise, performance requirements, integration needs, and development velocity.

Most projects work fine with REST. Some benefit from GraphQL. Very few need to go all-in on either.

Check out the GraphQL documentation when you're ready to experiment, or start with the REST quickstart. Grab your API key and build something.
