They changed the API and everything broke
One ordinary morning, without you touching anything, an automation stops working. The reason? An outside service — your payment gateway, your CRM, a social network — changed something internally. They didn't tell you, or the warning got lost among a hundred emails. Your robot is now speaking a language nobody understands anymore.
What an "API" is in plain words
Don't let the word scare you. An API is simply the way two programs talk to each other. Your website tells the bank "charge this"; the bank replies "done." That conversation has rules. As long as the rules don't change, everything's fine.
The problem is you don't set those rules. The outside service does. And one day they change them.
Why they change (and why it catches you out)
- They improve their product. They release a new version and retire the old one. Your automation was still using the old one.
- They close a security hole. Sometimes the change is good for everyone, but it breaks whatever was set up the old way.
- They change the terms. What used to be free now costs money, or what you could do a thousand times a day is now capped at a hundred.
And the warning, when there is one, usually arrives by email to an address nobody checks, six months ahead, in technical language nobody on your team understands.
A fragile integration vs one with a safety net
A fragile integration assumes the other side will never change or fail. The day it fails, it crashes loudly and takes down whatever depends on it.
An integration with a safety net assumes the opposite: the other side will fail sooner or later, and it prepares for that day.
How to build a connection that holds
- It alerts when something changes. If the outside service's reply stops being what's expected, you find out the same day — not three weeks later via an angry customer.
- It retries sensibly. If the service is briefly down, the automation waits and tries again, instead of giving up or hammering it with requests.
- It fails safely. If it really can't, it stops cleanly and saves what's pending, without leaving data half-done or charges duplicated.
- It doesn't hang on a single thread. Where possible, have a plan B if the main service goes down.
The part almost nobody watches
Here's an important detail: when an outside service changes, it can break your automation — and sometimes it opens a security hole too. A connection that stops validating properly, a password left somewhere no longer protected as before. That's why watching your integrations is also watching your security.
At NUDAYOSH we start from the assumption that everything outside will change, and we build automations with that in mind from day one: they alert, they retry sensibly, and if all else fails, they stop without doing harm. Because the problem isn't that a service changes — that's guaranteed to happen. The problem is finding out late.
