Your application relies on multiple third-party APIs. What do you do when one of them goes down?

Once aware of the issue, assess the impact on your application. If there's a backup or secondary service that can be switched to temporarily, do so. If not, it may be necessary to disable certain features that rely on the API until the service is restored. Communicate clearly and promptly with your users, informing them of the issue, what to expect, and what is being done to resolve it. Transparency goes a long way in maintaining trust. In the background, contact the third-party service provider for information on the outage and expected resolution time. Use this information to update your users accordingly. Longer-term strategies include implementing fallback methods or redundant systems to handle future outages more seamlessly.
