Imagine waking up to find your favourite app has suddenly stopped working because a key feature changed overnight, frustrating, right? When a third-party API update throws your web application into chaos, the first step is to assess what's changed. Dig into the API documentation or changelogs to understand the updates and how they impact your app. Next, decide whether you can quickly adapt your code to accommodate the changes or if you need to roll back to a previous stable version to keep things running. Communicate openly with your users about the issue and your plan to fix it, they'll appreciate the transparency. Reach out to the API provider for support if needed. Once a solution, thoroughly test before redeploying.

First, stay calm—panic fixes nothing. Check what the API changed, like finding out why your favorite pizza place stopped delivering. Update your app to match the new rules. If it’s broken badly, set up a quick patch or temporary workaround to keep things running. Talk to the API team if needed—politely, no angry emails! Test fixes carefully, then roll them out. Finally, tell your users, "We fixed it!" and maybe send a thank-you email for their patience. Keep an eye on the app afterward—no surprises, please!

Identify the Problem 🔍: Dig into the API changes to understand what broke. Is it an endpoint? A data format? Knowing the root cause is half the battle. Keep Users in the Loop 📢: Don’t leave users in the dark. Send out clear, reassuring updates to let them know you’re on it and share a timeline for fixes if possible. Adapt or Roll Back 🔄: If possible, revert to a stable version of the API. If not, adjust your code to fit the new changes—quick fixes first, then long-term solutions.

In the first place, I don't see why a third-party API would update without you knowing about it. Any decent project tells the users when there are breaking changes and provide new endpoints for the new version and maintain the old ones everyone is still using the previous version and it's their choice to migrate to the new one or not. If we're talking about an internal API that's part of a library or package, then it's the same thing, why would it be automatically updated without you knowing about it? Any update to third-party services has to be tested and only be performed if there's a strong reason to do it, such as a huge security or performance fix.

Look at the application and API error logs to pinpoint the exact issues. Implement temporary workarounds or fallback mechanisms to keep the application functional while you work on a permanent fix.
