Since 2017, users have been anticipating Postman's support for the HTTP/2 protocol. After six years of waiting, Postman finally rolled out HTTP/2 support in August 2024. This long-awaited update aligns with the growing popularity of HTTP/2, which has been widely adopted due to its improved speed, efficiency, and performance over HTTP/1.1.
With this rise in HTTP/2 usage, the demand for API testing tools supporting this protocol has grown significantly. In this article, we will provide an overview of HTTP/2, explore the advantages of testing APIs with HTTP/2 support, and introduce a better alternative approach for those looking to test HTTP/2 APIs efficiently.
What is HTTP/2?
HTTP/2, released in 2015, is a new version of the HTTP protocol designed to address the limitations of HTTP/1.1. It introduces several key features to enhance web communication:
- Header Compression: HTTP/2 implements header compression, significantly reducing communication overhead.
- Multiplexing: It allows multiple data streams to be transferred simultaneously over a single TCP connection, improving communication efficiency.
- Server Push: Server push enables the server to proactively send data it anticipates the client will need, leading to quicker data retrieval on the client side.
While HTTP/2 offers these advancements, it maintains backward compatibility with HTTP/1.1. Most major browsers and web servers have already embraced HTTP/2 support, gradually contributing to its adoption as the next-generation protocol for faster and more efficient web communication.
Does POSTMAN Support HTTP/2 Request in 2023?
No, Postman doesn't support HTTP/2 in 2023.
Postman has long been the go-to tool for API testing, but its lack of HTTP/2 support until August 2024 left many users frustrated. Despite growing demand since 2017, Postman only recently added support for HTTP/2, years after the protocol had become the standard for many APIs, such as Apple Push Notification Service (APNs). Before this update, attempting to test HTTP/2 APIs with Postman often resulted in errors like "Could not get a response," leading to failed tests and unreliable results when interacting with servers like https://api.sandbox.push.apple.com/

Easily Test HTTP2 APIs with Apidog
The latest version of Apidog now fully supports the HTTP/2 protocol, enabling you to easily test HTTP/2 APIs just like you would with regular HTTP APIs.
Here's how to get started:
- Open Apidog and create a new request.
2. Sending the endpoint URL, such as "https://api.sandbox.push.apple.com/," results in successful response retrieval without errors.
Additionally, within the "Settings," you can choose between HTTP and HTTPS connection methods to specify your preference for HTTP/2 support.
3. You can successfully get the response without any error by clicking the "Send" button.
Selecting the HTTPS Connection Method
HTTP/1.1: Choose this option for the traditional HTTP/1.1 connection protocol, ideal for servers using HTTP 1.1 or earlier.
HTTP/2 ALPN: By selecting HTTP/2 ALPN, Apidog utilizes Application-Layer Protocol Negotiation to establish connections. It first attempts a connection over HTTP/2, and will seamlessly fall back to HTTP/1.1 if the server lacks HTTP/2 support. This adaptive approach enables Apidog to automatically determine and use the protocol supported by your API, allowing easy testing of HTTP/2 APIs.
Selecting the HTTP Connection Method
HTTP/1.1: Choosing HTTP/1.1 forces this protocol to be used for all connections. Only HTTP/1.1 servers will be reachable.
HTTP/2 Prior Knowledge: Choosing HTTP/2 Prior Knowledge ensures a direct HTTP/2 connection with no fallback option. If the server lacks support for HTTP/2, the connection will fail, and there will be no attempt to use HTTP/1.1.
Conclusion
Both Apidog and Postman support HTTP/2 now. Apidog's HTTP/2 ALPN connection automatically detects the server's protocol, ensuring optimal communication. It is also possible to specify HTTP/2 directly in the settings. As an API testing tool, Apidog presents itself as a robust alternative to Postman, offering the means to embrace the future of API testing with confidence. Â
