Front API: Node.js script to merge contacts by email handle

README.md

merge-contacts.js

Uses the Front POST /contacts/merge API endpoint see docs to merge multiple contacts into a single contact record.

Installation

1. Save the merge-contacts.js file to your local machine.
2. Navigate to the directory you saved it.
3. Run npm install axios to install the Axios HTTP client
4. Edit the merge-contacts.js file to save your Front API token
5. Edit the merge-contacts.js file to save your list of contacts to merge.
6. When setup is complete, run node merge-contacts.js to execute the file. Progress will be printed to your terminal in real-time.

You should save the contacts as an array of arrays, with the primary contact listed first in each array.

Using the example provided in the code;

const emailArrays = [
  ['[email protected]', '[email protected]', '[email protected]'],
  ['[email protected]', '[email protected]'],
  ['[email protected]', '[email protected]'],
]

For the first record, handles '[email protected]' and '[email protected]' will be merged into the '[email protected]' contact record.

merge-contacts.js

const axios = require('axios');

// Your Front API token. Create one at Front Settings > Developers > API Tokens
const FRONT_API_TOKEN = 'YOUR_FRONT_API_TOKEN'

// Array of arrays of emails to merge.
// The first email will be the primary email, any subsequent emails in the array will be merged into the primary email.
// For this sample, the '[email protected]' contact will gain the secondary handles '[email protected]' and '[email protected]'
const emailArrays = [
  ['[email protected]', '[email protected]', '[email protected]'],
  ['[email protected]', '[email protected]'],
  ['[email protected]', '[email protected]'],
]

async function run() {
  for (const emails of emailArrays) {
    const primaryEmail = emails[0]
    const secondaryEmails = emails.slice(1)

    const primaryId = await getContactIdByEmail(primaryEmail)

    const mergePayload = {
      target_contact_id: primaryId,
      contact_ids: await Promise.all(secondaryEmails.map(async (email) => getContactIdByEmail(email))),
    }

    const response = await axios.post('https://api2.frontapp.com/contacts/merge', mergePayload, {
      headers: {
        'Authorization': `Bearer ${FRONT_API_TOKEN}`,
        'Content-Type': 'application/json',
      }
    })

    const mergedContact = response.data

    console.log(`✅ ID: ${mergedContact.id} Name: ${mergedContact.name}\nEmails: ${mergedContact.handles.map((handle) => handle.handle).join(', ')}\n--`)

    // Snooze for 1 second to avoid rate limiting
    await snooze(1_000)
  }
}

/**
 * Given a contact email, return the contact ID
 * @param {*} email
 * @returns id (string)
 */
async function getContactIdByEmail(email) {
  try {
    const resp = await axios.get(`https://api2.frontapp.com/contacts/alt:email:${email}`, {
      headers: {
        'Authorization': `Bearer ${FRONT_API_TOKEN}`,
      }
    })

    return resp.data.id
  } catch (error) {
    console.error("Error:", error)
    throw error
  }
