I'm trying to store response.data into a variable that can then be used outside of it's scope however it seems to always come back as undefined.

As you can see in the code, the first axios calls returns a token and then I later want to be able to use this token within the headers of the POST call.

const server = () => {
  var token;

  axios.get('http://xxxxx').then(
    response => {
      token = response.data;
    }
  );

  var configuration = {
    configToken: token
  };

  async function login() {
    return fetch('https://xxxx', {
      method: 'POST',
      headers: {
        Authorization: `Bearer ${configuration.configToken}`,
      },
    })
  }

  login();
};

export default server;
