How to Properly POST JSON Data Using cURL? or What’s the Correct Way to POST JSON with cURL?

"What’s the Correct Way to POST JSON with cURL?"

Hey folks,

I keep messing up when trying to post json curl requests. Like, I *think* I’m doing it right, but the server keeps yelling at me.

Here’s what I’m doing:
```bash
curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' http://example.com/api
```
But sometimes it just... doesn’t work? Am I missing something obvious?

Also, do I *really* need the `-X POST`? Feels redundant, but I see it everywhere. And what if my json has quotes inside? Do I need to escape them?

Pls halp, my sanity is slipping. 🙃

(Also, if you’ve got a better one-liner to post json curl, drop it below!)
