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.

If our 3rd party API does not have a disaster recovery we should put this risk on a high risk list, and if possible to find alternative solution for DR plan. However, our application should be enough modular to keep business service online (Business Continuity) and make sure the message distributes immediately to our internal and external stakeholders and end users to be aware of the lack of service bring the recovery period.

✔️ Implement fallback mechanisms (e.g., cache last successful response or use alternative service) ✔️ Use Resilience4J for circuit breakers and retry strategies ✔️ Monitor API status and alert the team ✔️ Keep users informed of degraded functionality ✔️ Log failures for future analysis ✔️ Ensure graceful degradation of features to minimize impact
