What are the several types of AWS API Gateway Protocols?

Amazon API Gateway helps varied protocols for exposing APIs, together with:

1. RESTful API

That is the commonest and extensively used protocol for net APIs. Amazon API Gateway permits you to create and handle RESTful APIs, the place you outline API assets, strategies (similar to GET, POST, PUT, DELETE, and so forth.), and HTTP request and response mappings utilizing API Gateway’s REST API mannequin.

Main use-cases embody

  • Constructing conventional net APIs with customary HTTP strategies (GET, POST, PUT, DELETE, and so forth.) and resource-based URLs.
  • Exposing APIs for legacy programs or third-party integrations that comply with RESTful ideas.
  • Constructing APIs which might be consumed by a variety of purchasers, similar to net browsers, cell apps, and IoT units.

2. WebSocket API

WebSocket is a protocol that permits bidirectional communication between net purchasers and servers over a single, long-lived connection. With Amazon API Gateway’s WebSocket API, you’ll be able to create real-time, interactive APIs that help two-way communication between purchasers and servers, making it appropriate to be used instances like chat purposes, gaming, and notifications.

Main use-cases embody

  • Constructing real-time purposes that require bidirectional communication between purchasers and servers, similar to chat purposes, gaming, and collaborative enhancing instruments.
  • Enabling real-time notifications, alerts, or event-driven communication in your purposes.
  • Constructing interactive purposes that require prompt updates and push notifications.


It is a extra streamlined and simplified protocol for constructing APIs with Amazon API Gateway. HTTP APIs are designed for serverless architectures and supply options like automated CORS dealing with, simplified authorization, and a extra environment friendly payload format in comparison with RESTful APIs. HTTP APIs are typically beneficial for constructing APIs for serverless purposes, single-page purposes (SPAs), and cell purposes.

Main use-cases embody

  • Constructing serverless purposes that use AWS Lambda because the backend, the place APIs act as triggers for Lambda features.
  • Constructing APIs for single-page purposes (SPAs) or cell purposes that require simplified authorization and CORS dealing with.
  • Constructing APIs that have to deal with a lot of requests with low latency, as HTTP APIs are designed to be extremely performant and cost-effective for high-scale workloads.


It’s price noting that every of those protocols has its personal use instances, options, and trade-offs, so it’s essential to rigorously contemplate your particular necessities and use case when selecting the suitable protocol in your API in AWS API Gateway.

It’s essential to notice that these are just a few widespread use instances, and the suitable protocol in your API in Amazon API Gateway relies on your particular necessities and use case. It’s beneficial to completely perceive the options, capabilities, and trade-offs of every protocol earlier than selecting the suitable one in your API implementation.
