Testing APIs is noisy when filtering only by URL-irrelevant requests slow you down and hide integration issues. Dev Proxy lets you filter by specific headers and values for focused debugging. Get cleaner logs, diagnose faster, and ship better apps.

HTTP files are awesome for quickly testing APIs. Dev Proxy auto-generates HTTP files from API traffic. This saves time, boosts security, and makes sharing reproducible API scenarios easy for development and collaboration.

This Friday I’ll be virtually joining the XeDotNet community for a talk in Italian about agents + Copilot 🚀
We’ll cover:

- How Agent Builder, Copilot Studio, and the Agents SDK fit together
- What this means for devs + organizations

Free to join here: www.xedotnet.org/eventi/un-ec...
Un’ecosistema di agenti per Microsoft 365 Copilot | XE - Development User Group
[Online Meeting] L’esperienza di Microsoft 365 Copilot si è recentemente arricchita di un vasto ecosistema di agenti: dai declarative agent, realizzati con strumenti come Copilot Studio o Microsoft 365 Agents Toolkit; ai custom engine agent, che possono essere sviluppati con Microsoft 365 Agents SDK, Teams AI Library, Semantic Kernel e Azure AI Foundry. Siete un po’ confusi? Niente paura, nel corso di questa sessione capiremo meglio le differenze e quali strumenti utilizzare in base allo scenario che si vuole implementare.

Hardcoded tokens or skipped auth checks cause unreliable authentication simulation, slowing you down. Dev Proxy's AuthPlugin simulates real API key/OAuth2 flows, enforcing auth scenarios. Test auth reliably and launch with confidence.

26 yrs after its initial release, I finally finished Half-life.

I’ve lost count how many times I’ve started playing it and then just stopped for no real reason.

The graphics are dated by today’s standards but the story and gameplay is still brilliant.

Run. Think. Shoot. Live.

Please don't have your API return a 200 OK with an error code and add to that list.

Closed the week on a high note. @garrytrinder.dev and I have done some really cool stuff for @devproxy.bsky.social. If you use it, be sure you’ve got the Dev Proxy Toolkit VSCode extension so that you can manage configs using natural language. 💪

For debugging code we need symbols/source maps. For debugging APIs we need access to raw requests and responses with their headers. If you’re building an app or an SDK be sure to have a switch to expose this information.
