I am looking at an API that I would like to use and am having a hard time figuring out how to use it. This API needs me to give URL requests to a website and it will respond with JSON data. An example request that they give is:
curl -i -H "X-Accept-Datetime-Format: UNIX" "https://api-fxpractice.oanda.com/v1/candles?instrument=EUR_USD&start=137849394&count=1"
I can not figure out how to make a request like this in a php script. I have looked at many websites but I still don't understand what the -i and the -H are used for. Furthermore I am having trouble finding a website that will explain how the data :"X-Accept-Datetime-Format: UNIX"
is supposed to be sent to a website through a URL request in php. All help in finding a website that will better explain what all of this means and how I can create a php script to run this will be very helpful. Thank you very much for your help!
