Find a right way to convert cURL to a POST request axios

Hi guys just what the title says, I couldn’t find a solution.

Here the cURl:

curl "https://test.api.amadeus.com/v1/security/oauth2/token" 
     -H "Content-Type: application/x-www-form-urlencoded" 
     -d "grant_type=client_credentials&client_id={client_id}&client_secret={client_secret}"

Here is my code that is getting a 400 error from server:

const getToken = async () => {
try {
  const res = await axios.post(
    "https://test.api.amadeus.com/v1/security/oauth2/token",
    null,
    {
      params: {
        client_id: process.env.REACT_APP_AMADEUS_API_KEY,
        client_secret: process.env.REACT_APP_AMADEUS_SECRET_API_KEY,
        grant_type: "client_credentials",
      },
      headers: {
        "Content-Type": "application/x-www-form-urlencoded",
      },
    }
  );
  console.log(res);
} catch (error) {
  console.log(error);
}};
