fix misspelled email domains with hubdb and custom coded action.js

const request = require('request');

exports.main = async (event, callback) => {
  
  const email = event.inputFields['email'];  
  let domain = email.split('@')[1];
  let username = email.split('@')[0];
  
  var options = {
    'method': 'GET',
    'url': 'https://api.hubapi.com/hubdb/api/v2/tables/5486243/rows?name=' + domain,
    'headers': {
      'Authorization': 'Bearer ' + process.env.HUBDBKEY
    }
  };
  request(options, function (error, response) {
    if (error) throw new Error(error);
    const obj = JSON.parse(response.body); 
    let corrected_domain = obj.objects[0].values['2'];
    let corrected_email = username + '@' + corrected_domain;
       
    callback({
      outputFields: {
        former_email: email,
        corrected_domain: corrected_domain,
        corrected_email: corrected_email
      }
    });
  });

  
}

Create a hubdb table with the domain misspellings and corrected domains.
Create a list of contacts with domain misspellings (filter by email contains misspelling)
Create a workflow with trigger being member of said list ^
Custom coded action that splits username from domain, looks up misspelled domain in hubdb, then returns corrected domain
Append username back to corrected domain and output the corrected email
