Which small developer utilities do you use when testing API integrations?
When working on API integrations, I often find that small utility tools can make testing and troubleshooting a lot easier. Things like JSON formatting, timestamp conversion, URL encoding, text manipulation, calculations, and unit conversion can save a surprising amount of time during development.
I’m curious what other developers here use when working with payment APIs and sandbox environments.
Do you rely mainly on browser-based utilities, IDE extensions, or your own scripts? I’ve been collecting some useful browser-based tools in DailyToolkit and would be interested in hearing which utilities other developers find most useful.
For API testing specifically, which small tool do you find yourself using repeatedly?
