How to making a post using custom headers

[Henrique Mendes Carvalho]

How to send the following json, in a post, with the headers?

{
"from":"WineShop",
"to":[
"5531984882884",
"5531984882886"
],
"text":"Wine shop grand opening at Monday 8pm. Don't forget glasses."
}


Headers Authorization and Content-Type.
