Always Add Timeouts to External API Calls

~1 min read
💡TL;DR

Never call external APIs without a timeout — one slow dependency can freeze your entire system.

One silent production killer: calling external APIs without a timeout.

If a third-party service hangs, your request hangs too… and suddenly:

  • API response time spikes
  • Threads get blocked
  • Users see loading forever

Most developers assume APIs will respond quickly. They don’t.

Always define a timeout.

Example:

  • Payment APIs
  • Email services
  • AI APIs
  • Internal microservices

Without timeout:
→ your system depends on someone else’s uptime

With timeout:
→ your system stays in control

Bonus:
Also implement retry logic with limits.
Rule:
“No timeout = future production issue”
