const key = "your key"
const qs = obj => {
return new URLSearchParams(obj).toString();
}

const data = qs({
q: word,
source: “en”,
target: “es”,
})

const options = {
method: “POST”,
url: “https://google-translate1.p.rapidapi.com/language/translate/v2”,
headers: {
“content-type”: “application/x-www-form-urlencoded”,
“x-rapidapi-key”: key,
“x-rapidapi-host”: “google-translate1.p.rapidapi.com”,
},
data: data,
};
axios
.request(options)
.then(function (response) {
console.log(response.data);
})
.catch(function (error) {
console.error(99, error);
});
