What makes an API integration delightful (or painful) for you? 🛠️

Hey developers of Product Hunt! 💻

As software engineers, nothing is worse than an API that takes hours to set up due to messy docs, complex auth flows, or high latency response times.

When building MailCheck API, our goal was simple:

1. Keep average response time under 50ms.

2. Zero complex dependencies—a simple REST call with instant JSON feedback.

3. Drop-in snippets for Node, Python, Dart/Flutter, and cURL.

I’d love to know your developer preferences:

• Do you prefer testing APIs directly via an interactive Swagger/OpenAPI docs portal, or do you pull postman collections straight into your IDE?
