POST a JSON to and API

Rails
1

Hello Folks,

I’m trying to POST a JSON object to an API:

{
“input”: “http://www.example.com/input/video.mov”,
“output”: [
{
“base_url”: “http://www.example.com/output/”,
“filename”: “video.mp4”,
“thumbnails”: {
“number”: 1,
“size”: “86x66”
}
}
]
}

What’s the best way to post this JSON to an API, e.g.
http://www.example.com/api?
How should I create a function that will take an input file name
(video.mov) and output a JSON object as well as POST it to an API?

Thanks!
