How do you encode api key to base64 for freshdesk?

I have my freshdesk api key in iparams. I need to encode it in base64 in order to submit via API. I can’t see a way to do this.

This page suggests “encode” but I get “ReferenceError: encode is not defined”.


I also tried Buffer as shown below per this stackoverflow article but I get “ReferenceError: Buffer is not defined”.


Any suggestions?

Here is one way which can help you @stevemc,

From frontend

Let’s say this is a input field

        label="Freshdesk API Key"
        placeholder="Freshdesk Portal > Profile > Copy API Key"
let apiKey = document.querySelector('.secure-field');

function postConfigs() {
        return {
          __meta: {
            secure: ['apiKey']
          api_key: apiKey.value,

      async function validate() {
        var URL = `https://${domain.value}/api/v2/tickets`;
        var base64Encoded = btoa(apiKey.value);
        var options = {
          headers: {
            Authorization: `Basic ${base64Encoded}`,
            'Content-Type': 'application/json'
        try {
          let { status } = await client.request.get(URL, options);
          if (status == 200) return true;
        } catch (error) {
          return false;

In backend, as in server.js

You can use a npm package, for example this one - safe-buffer - npm
And try to use Buffer.from(..) by listing the npm package in the manifest.

Native Node packages are blocked because of the security concerns of the platform. Hope those help.

Though Saif did answer the question, I wanted to spell out the solution in a little more detail:

  1. Install safr-buffer module
    npm install safr-buffer

  2. Add following to the manifest.json:
    “dependencies”: {
    “safe-buffer”: “5.2.1”

  3. Add following to top of your server.js:
    var Buffer = require(‘safe-buffer’).Buffer

  4. use following to base64 encode a string:
    base64Key=Buffer.from(“some string”).toString(‘base64’)

That’s it. now use base64Key in your Authorization header
header = "Authorization: Basic " + base64Key


Appreciate you adding more details, @stevemc !
