Getting startedįrom the very beginning, we noticed that the most arduous thing getting in the way of using WebSocket APIs is the very act of connecting to a WebSocket API server. Take it for a spin and give us feedback in our WebSocket discussion forum. In this tab, you can input your WebSocket API URL, establish a connection, then send and receive messages seamlessly. In the latest version of Postman, you can now hit the “New” button in the left sidebar and open a WebSocket Request tab. The protocol enables continuous two-way communication between your browser and the web server, and for Postman, it has meant the advent of a whole new paradigm of asynchronous APIs. Support for the WebSocket protocol is one of the most popular feature requests we’ve received from the Postman community. This key update to our API platform is currently available in public beta with Postman v8.5 and above. Use these captured requests to build and publish documentation or mock servers without needing to manually author requests.Today, we are excited to announce that Postman now supports WebSocket APIs.This capability enables you to:Ĭheck all API calls that are being made between the client and the server, and save these into Postman’s history or a specific collection. You’re now all set to capture traffic in Postman, even if it has HSTS enabled. Postman proxy certificate Postman proxy certificate permissions Select Always Trust only for Secure Sockets Layer (SSL).Click on the imported Postman certificate, and when the following window pops-up.Choose “ System” from the keychain option.Navigate to ~/Library/Application Support/Postman/proxy.Here are the steps to capture traffic if you’re on OSX: This lets your browser consume the endpoint’s response without showing a security warning. When Postman’s proxy encounters a request to a new HTTPS domain, it’ll create an SSL certificate on the fly. The CA certificate tells your system or browser that Postman is a valid issuer of certificates (similar to Verisign, Comodo, and Let’s Encrypt). Check our documentation for details on how to do this. To capture traffic for HSTS endpoints, you’ll need to install the self-signed root CA (Certificate Authority) certificate generated by Postman. And with the new capability we’re announcing today, Postman now addresses this scenario. However, if you’re testing APIs on a remote environment or those of third-party providers like Google, there’s no way to opt out of HSTS. Often, local development happens without HTTPS, so the problem mentioned above is a non-issue. For the client applications (browsers, in many cases) to continue to trust their response, they need to trust Postman’s certificate authority. However, this poses a problem for tools that are meant to inspect traffic flowing over the wire. Without HSTS enabled, some browsers give users the option of proceeding after showing a warning that loophole is closed when websites implement HSTS. According to a source, 19.3% of websites use HSTS. This is critical to prevent the exploitation of users from man-in-the-middle attacks. HSTS, or HTTP Strict Transport Security, is a web standard that forces web browsers and other clients to only let traffic through if the SSL certificate can be verified. But today, that changes: We’re happy to fulfill a long-standing feature request from our community by fully supporting HTTPS traffic in addition to HTTP traffic. However, flows with requests made over HTTPS (especially to hosts with HSTS enabled) traditionally haven’t been as smooth. Capturing HTTP traffic works well to help with the debugging process-check out an earlier blog post that explains how you can capture requests made from mobile devices. Postman’s proxy is a good example: It lets you capture traffic and debug your APIs easily, whether on your local environment or a remote one. We’ve heard this loud and clear from Postman users, and that’s why we’re always working to make API testing and debugging faster for you. Unsurprisingly, according to the 2020 State of the API Report by Postman, developers also feel like they should spend less time debugging (ideal state: 10.75%) than they actually do (existing state: 17%) while working with APIs. Developers spend a lot of time debugging and manually testing APIs.
