Here is the example - 

request_body <- data.frame(
language = c("en","en"),
id = c("1","2"),
text = c("This is wasted! I'm angry","This is awesome! Good Job Team! appreciated")
)

Converting the Request body(Dataframe) to Request body(JSON)

require(jsonlite)
request_body_json <- toJSON(list(documents = request_body), auto_unbox = TRUE)

Below we are calling API (Adding Request headers using add_headers)

require(httr)
result <- POST("https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment",
body = request_body_json,
add_headers(.headers = c("Content-Type"="application/json","Ocp-Apim-Subscription-Key"="my_subscrition_key")))
Output <- content(result)

Show Output
