4 hours of debugging. Zero lines of "my" code changed. 🙃 We’ve all been there: An integration that has been rock-solid for months suddenly breaks. The clients are frustrated, the manager is asking for answers, and you’re staring at a log file that says… absolutely nothing. No errors. No warnings. After a deep-dive investigation, I found the culprit: The third-party service changed their response/request format without a single update to their documentation. The fix? I had to "blindly" map a new parameter from their response back into the request body. Suddenly, everything clicked. My takeaways: Logs aren't everything: Sometimes the "silent" changes are the deadliest. Docs are a contract: If you change the API, update the docs. Period. Have you ever lost a half-day to a "ghost" change in a third-party API? Let's commiserate in the comments. 👇 #SoftwareEngineering #API #WebDevelopment #Debugging #Backend #TechLife #php #laravel #symfony
I would suggest to validate response more strictly. Next time you at least will see if structure is invalid
I actually had similar experience - backend app crashed due to unexpected new fields in a request body. Our frontend used third-party service and while for the frontend those changes were not show-stopper, backend suffered when those new fields appeared suddenly. At the time I was not able to fix that at the backend (other than add those fields into backend service's entity), but later my teammate was able to update the frontend codebase (React) to use only fields already mapped to backend service (SAP). Now I have some doubts whether I missed something I could have implemented myself on the backend to make that service more robust.While it's reasonable to expect docs update, that's not always possible to get in reality (like your example demonstrates), especially if you depend on the third-party.I assume you experience some limitations in your service - where you can't provide a certain level of flexibility for the data structures. Is it correct?
