how to send authorization throught get request axios . pinterest api v5

Question

i tried to read the pins from pinterest api but i don't know how to authorize using the app id and the secret app id. i tried to read the docs but i didn't understand the way to make authorization and get the pins list

const axios = require("axios");
const username = "";
const password = "";

const token = Buffer.from(`${username}:${password}`, "utf8").toString("base64");

const url =
  "https://api.pinterest.com/v5/pins/14425661293229561&client_id=1477150&scope=boards:read,pins:read";

axios.post(url, {
  headers: {
    Authorization: `Basic ${token}`,
  },
});

axios
  .get(url, {
    headers: {
      Authorization: `Basic ${token}`,
    },
  })
  .then((res) => {
    console.log(res.code);
  })
  .catch((e) => console.log("hello"));

Here is an example request to the OAuth page:

https://www.pinterest.com/oauth/?
client_id={YOUR_CLIENT_ID}&
redirect_uri={YOUR_REDIRECT_URI}&
response_type=code&
scope=boards:read,pins:read&
state={YOUR_OPTIONAL_STRING}

https://api.pinterest.com/v5/pins/{pin_id}
