Mastering HubSpot and Twilio SMS Integration: A Complete Guide to Custom API Solutions
In today’s digital landscape, effective customer communication is more crucial than ever. While email remains a cornerstone of customer engagement, SMS messaging has emerged as a powerful channel with open rates as high as 98%. By integrating HubSpot’s robust CRM capabilities with Twilio’s powerful SMS API, businesses can create sophisticated, automated communication workflows that enhance customer engagement and drive better results.
This comprehensive guide will walk you through creating custom integrations between HubSpot and Twilio SMS, enabling you to build powerful automated messaging solutions that align with your business needs.
Understanding the Business Need
Before diving into the technical implementation, let’s explore why combining HubSpot and Twilio SMS can transform your customer communication strategy:
- Immediate Engagement: SMS messages are typically read within 3 minutes of receipt
- Higher Response Rates: SMS has a response rate 7.5x higher than email
- Automated Workflows: Trigger SMS messages based on HubSpot contact properties and activities
- Enhanced Customer Experience: Provide timely, relevant information through customers’ preferred channels
- Better Lead Nurturing: Complement email campaigns with strategic SMS touchpoints
Prerequisites
To follow this guide, you’ll need:
- A HubSpot account with API access (Professional or Enterprise tier)
- A Twilio account with:
- Account SID
- Auth Token
- Active phone number
- Node.js (version 14 or higher)
- Basic understanding of:
- JavaScript/Node.js
- REST APIs
- HubSpot workflows
- Async/await patterns
Setting Up Your Integration Environment
First, let’s set up our development environment and install necessary dependencies:
const express = require('express');
const hubspot = require('@hubspot/api-client');
const twilio = require('twilio');
// Initialize HubSpot client
const hubspotClient = new hubspot.Client({
accessToken: process.env.HUBSPOT_ACCESS_TOKEN
});
// Initialize Twilio client
const twilioClient = twilio(
process.env.TWILIO_ACCOUNT_SID,
process.env.TWILIO_AUTH_TOKEN
);
const app = express();
app.use(express.json());
Environment variables should be stored in a `.env` file:
HUBSPOT_ACCESS_TOKEN=your_access_token
TWILIO_ACCOUNT_SID=your_account_sid
TWILIO_AUTH_TOKEN=your_auth_token
TWILIO_PHONE_NUMBER=your_twilio_number
Building Basic SMS Integration
Let’s start with a basic integration that sends SMS messages to HubSpot contacts when specific triggers occur:
async function sendSMSToContact(contactId, message) {
try {
// Get contact details from HubSpot
const contact = await hubspotClient.crm.contacts.basicApi.getById(
contactId,
['phone', 'firstname']
);
// Format phone number for international format
const phoneNumber = formatPhoneNumber(contact.properties.phone);
// Send SMS via Twilio
const response = await twilioClient.messages.create({
body: message,
to: phoneNumber,
from: process.env.TWILIO_PHONE_NUMBER
});
// Log success in HubSpot timeline
await logSMSInHubSpot(contactId, message, response.sid);
return response;
} catch (error) {
console.error('Error sending SMS:', error);
throw error;
}
}
// Helper function to format phone numbers
function formatPhoneNumber(phone) {
// Remove any non-numeric characters
const cleaned = phone.replace(/\D/g, '');
// Add international format if needed
return cleaned.startsWith('1') ? `+${cleaned}` : `+1${cleaned}`;
}
// Log SMS activity in HubSpot timeline
async function logSMSInHubSpot(contactId, message, twilioSid) {
try {
await hubspotClient.crm.timeline.events.apiCreateToken({
eventTemplateId: 'sms_sent',
tokens: [{
name: 'message',
value: message
}, {
name: 'twilio_sid',
value: twilioSid
}],
objectId: contactId
});
} catch (error) {
console.error('Error logging to HubSpot:', error);
throw error;
}
}
Advanced Integration Patterns
Now let’s explore more sophisticated integration patterns that leverage HubSpot’s workflow capabilities:
1). Workflow-Triggered SMS
Create an endpoint that HubSpot workflows can call to trigger SMS messages:
app.post('/api/trigger-workflow-sms', async (req, res) => {
const { contactId, workflowId, messageTemplate } = req.body;
try {
// Get workflow properties
const workflow = await hubspotClient.automation.workflows.get(workflowId);
// Get contact properties for personalization
const contact = await hubspotClient.crm.contacts.basicApi.getById(
contactId,
['firstname', 'lastname', 'company']
);
// Personalize message
const personalizedMessage = personalizeMessage(
messageTemplate,
contact.properties
);
// Send SMS
const smsResponse = await sendSMSToContact(contactId, personalizedMessage);
res.json({
success: true,
messageSid: smsResponse.sid
});
} catch (error) {
console.error('Workflow SMS Error:', error);
res.status(500).json({
success: false,
error: error.message
});
}
});
function personalizeMessage(template, properties) {
return template.replace(/\{\{(\w+)\}\}/g, (match, property) => {
return properties[property] || match;
});
}
2). Two-Way Communication Handler
Enable two-way communication by handling incoming SMS responses:
app.post('/api/twilio-webhook', async (req, res) => {
const {
From: phoneNumber,
Body: message,
MessageSid: messageSid
} = req.body;
try {
// Find HubSpot contact by phone number
const contact = await findContactByPhone(phoneNumber);
if (contact) {
// Create a new note in HubSpot
await hubspotClient.crm.contacts.notesApi.create({
properties: {
hs_timestamp: Date.now(),
hs_note_body: `SMS Response: ${message}`,
hs_attachment_ids: []
},
associations: [{
to: { id: contact.id },
types: [{ category: "HUBSPOT_DEFINED", typeId: "contact_to_note" }]
}]
});
// Update contact property for last SMS response
await hubspotClient.crm.contacts.basicApi.update(contact.id, {
properties: {
last_sms_response: message,
last_sms_response_date: Date.now()
}
});
}
res.status(200).send('OK');
} catch (error) {
console.error('Webhook Error:', error);
res.status(500).send('Error processing webhook');
}
});
async function findContactByPhone(phoneNumber) {
const searchResponse = await hubspotClient.crm.contacts.searchApi.doSearch({
filterGroups: [{
filters: [{
propertyName: 'phone',
operator: 'EQ',
value: phoneNumber.replace('+1', '')
}]
}]
});
return searchResponse.results[0];
}
3). Bulk SMS Campaigns
Implement bulk SMS sending for marketing campaigns:
async function sendBulkSMS(listId, messageTemplate, batchSize = 50) {
let after = 0;
let processedCount = 0;
while (true) {
// Get contacts from list
const contactsResponse = await hubspotClient.lists.getListContacts({
listId,
count: batchSize,
vidOffset: after
});
if (!contactsResponse.contacts.length) {
break;
}
// Process batch
const promises = contactsResponse.contacts.map(contact =>
sendSMSToContact(
contact.vid,
personalizeMessage(messageTemplate, contact.properties)
)
);
// Wait for batch to complete
await Promise.allSettled(promises);
processedCount += contactsResponse.contacts.length;
after = contactsResponse.vid-offset;
// Respect Twilio rate limits
await new Promise(resolve => setTimeout(resolve, 1000));
}
return processedCount;
}
