How to send the authorization header using Axios

To set headers in an Axios POST request, pass a third object to the axios.post() call.

You might already be using the second parameter to send data, and if you pass 2 objects after the URL string, the first is the data and the second is the configuration object, where you add a headers property containing another object:

axios.post(url, {  data: {    ...  }})

axios.post(url, {  //...data}, {  headers: {    ...  }})

To set the authorization header, call it like this:

const token = '..your token..'axios.post(url, {  //...data}, {  headers: {    'Authorization': `Basic ${token}`   }})

(the authorization token might differ, check with the app you’re using)

To set headers in an Axios GET request, pass a second object to the axios.get() call, for example this is a GitHub GET request to /user:

axios.get('https://api.github.com/user', {  headers: {    'Authorization': `token ${access_token}`  }}).then((res) => {  console.log(res.data)}).catch((error) => {  console.error(error)})

I was doing some work with the WordPress API, and I had to authenticate to perform a POST request to a website.

The easiest way for me was to use basic authentication.

I was using Axios, so I set the Authorization header to the POST request in this way:

const username = ''const password = ''const token = Buffer.from(`${username}:${password}`, 'utf8').toString('base64')const url = 'https://...'const data = {  ...}axios.post(url, data, {  headers: {    'Authorization': `Basic ${token}`  },})
