If your app's architecture ignores unexpected failures, you might need a new Architect. Apps like food ordering, commute, and even banks fail. Here's how to stay prepared: 1. Friendly Neighbor Rule: Show users a calm message like, "Oops! Quick chai break!" 2. Alien Invasion Theory: Treat APIs like unpredictable aliens. Use tools like Crashlytics to monitor issues. 3. Karachi Traffic Strategy: Use retry logic and circuit breakers to avoid hammering failing APIs. 4. Backup Dabba Plan: Cache key data to stay functional during outages. 5. Lifeguard Approach: Inform users promptly when things go wrong. Prepare for chaos, and users will stick with you — even when APIs misbehave.

In my experience, you should have a fallback mechanism. Show users some friendly messages and ask them to be patient. Sometimes, give them some credit as compensation if the failure lasts long.

As software engineers, we know how common it is for apps to rely on third-party APIs, like payment gateways, delivery systems, and Google Maps. These APIs are often essential for user interaction, and any failure can significantly impact the user experience. To improve system reliability and make the user experience smoother, follow these steps: Implement logging in your app to track failures. This will help you identify at which point a failure occurred, allowing you to diagnose and fix issues quickly. In case of failure, guide users to a clear message reassuring them that the issue is being addressed and will be resolved shortly. Offer backup solutions so that critical business functions are not disrupted by third-party failures.

Third-party APIs are great—until they fail. That’s why resilience is key. Start by researching API providers: How reputable are they? What guarantees and fallback plans do they offer? On your side, implement retry logic with exponential backoff to avoid overwhelming a failing API. A circuit breaker helps pause requests until recovery. Use fallbacks like caching with default or last known values to keep things running. Monitor failures with alerts, and for critical APIs, have a backup provider. The goal? Graceful degradation, not total failure. Did I miss anything?

If a third-party API unexpectedly fails, here’s how to handle it effectively: Implement Error Handling – Use try-catch blocks and meaningful error messages to inform users of temporary issues. Set Up Fallback Mechanisms – Cache recent data or provide limited offline functionality to maintain a good user experience. Use Retries with Exponential Backoff – Instead of overwhelming the API, retry requests with increasing delay intervals. Monitor API Status – Integrate monitoring tools or check the provider’s status page to detect failures early. Have an Alternative API or Manual Mode – If possible, switch to a backup API or allow users to proceed with partial functionality. Proactive planning ensures that API failures don’t disrupt your app.

Implement retries with exponential backoff, fallback mechanisms, and cache critical data. Monitor API health and have contingency plans to ensure seamless user experience.

When your mobile app depends on a third-party API, unexpected failures can impact user experience. Implement fallback mechanisms like cached data or alternative APIs to ensure continued functionality. Monitor API performance with real-time alerts for quick issue resolution. Transparent communication with users about outages helps maintain trust and manage expectations.

One other aspect that is important is that the problem refers to a Mobile app, so if the signature unexpectedly changes for an external API, then you will need a code change, but for Mobile apps, this is a potential problem as you would need to fix and release to the App Stores, which can't be done very fast. So, yes, you need to monitor, have a good user experience and mitigation to keep as much of the app working as possible (i.e. other features), but you should also consider - All calls to External APIs should not be directly from the Mobile App itself, rather it should be via your Gateway/BFI-type interface. You can fix an API call in your own code immediately without having to re-release your Mobile App to the App Stores.

When a third-party API fails, I implement fallbacks like cached data or limited offline functionality to keep the app usable. Monitoring and alerts help detect issues early for a quick response. If the outage impacts users, I ensure clear communication to manage expectations. Proactive planning minimises disruption.

Just update it to latest version. AND this response should not be 125 min characters, because be concise do not add story in your logics.
