Working on my budget app hobby project opened my eyes to SaaS API flaws

I've been working on a personal budget app as a side project, just for fun lol. It pulls data from a few banking APIs, and when one fails, the whole thing crashes. This helped me see how often B2b SaaS tools have similar issues with third-party integrations. For example, if a CRM API goes down, it can disrupt sales workflows big time. I think SaaS ops teams should focus more on robust error handling and fallbacks. It's wild how a small hobby project can reveal such a common problem. Maybe we need to test integrations more thoroughly in real-world scenarios.

Yeah, I read a tech blog last week about a CRM API outage that screwed over a bunch of small businesses. Their sales data got corrupted because the system didn't handle the failure right. It's like you said, without good error handling, everything falls apart. I heard some teams just assume APIs will always work, which is crazy. They need to plan for breaks and have backup plans. Real world testing would catch a lot of this before it becomes a crisis.

Dealt with a similar mess when our online scheduling tool had a major glitch. Lost a bunch of appointments because the system didn't fail gracefully. We started keeping a paper backup log for all bookings after that. It's a pain, but it beats losing customer data. Now we test for outages by randomly turning off features to see what breaks. Makes you realize how fragile these systems can be.

Run chaos tests weekly to find weak spots before customers do.

Wait but @shanef34, isn't that overkill? Randomly breaking stuff sounds like a great way to cause the very problems you're trying to avoid. And paper logs just add more work for no real gain.
