API Fundamentals
REST vs GraphQL vs Webhooks: Choosing the Right API Pattern
Compare the most common API patterns so you can pick the right approach for data delivery, flexibility, and automation.
Use REST for simple resource-based access
REST is often the default choice because it is familiar, cache-friendly, and easy to understand.
It works well when your domain maps cleanly to resources like users, invoices, or orders.
Action checklist
- Map business objects to resources.
- Keep endpoint naming consistent.
- Use standard HTTP methods where possible.
Use GraphQL when clients need flexible queries
GraphQL can reduce over-fetching when different clients need different fields from the same data model.
That flexibility comes with extra planning around schema design, caching, and query cost control.
Action checklist
- Confirm that flexible field selection solves a real problem.
- Plan for schema governance and query limits.
- Evaluate whether one API can serve multiple front ends cleanly.
Use webhooks for event-driven communication
Webhooks are best when another system should react as soon as something happens.
They are ideal for events like payment success, form submission, or record status changes.
Action checklist
- Identify the event that should trigger a notification.
- Confirm the receiving system can process retries safely.
- Sign webhook payloads where possible.
Match the pattern to the problem
The best API design is the one that fits the job with the least unnecessary complexity.
If the goal is stable CRUD access, REST may be enough. If the goal is flexible client queries, GraphQL may help. If the goal is push-based notifications, webhooks may be the right answer.
Action checklist
- Write the actual integration need in one sentence.
- Choose the simplest pattern that meets that need.
- Avoid mixing patterns without a clear reason.
