Best Practices for Handling Real-Time API Failures in Production?

Hi everyone,

I’m currently building a backend service that relies on multiple third-party APIs (payment, weather, and shipping). While everything runs fine in staging, I’m concerned about handling unexpected API failures in production — especially since these services are used in real-time by end users.

I’d love to hear how other developers in the community handle this.

Do you use circuit breakers or retries with exponential backoff?

What logging/alerting setup helps you catch these failures early?

How do you prevent cascading failures when one external API is down?

Any tips, patterns, or real-life examples would be much appreciated. Thanks in advance!
