Apollo is one of the most powerful prospecting tools for finding verified contacts and company information. HubSpot is a leading CRM used to manage contacts, companies, deals, and sales activity.
When we integrate Apollo with HubSpot, we can automatically sync new prospects into HubSpot, along with enriched data like email, phone number, job title, and company details. This helps the sales team work faster and eliminates manual data entry.
Why Integrate Apollo with HubSpot?
Apollo → HubSpot integration provides multiple benefits:
- Automatically create HubSpot contacts from Apollo
- Automatically create HubSpot companies from Apollo
- Sync enriched details (email, phone, job title, company domain, etc.)
- Prevent duplicate records using email and domain matching
- Ensure Apollo prospect lists are available in HubSpot for sales workflows
Prerequisite
Before connecting Apollo with HubSpot, ensure you have:
- Apollo account with admin/integration access
- HubSpot account with admin access
- Permission to install apps in HubSpot
- Proper CRM properties (optional, but recommended)
Let’s go step by step:
How to Connect Apollo with HubSpot
Step 1: Open Apollo Settings
Login to Apollo and go to the settings section.
Step 2: Go to Integrations
In Apollo, open the Integrations page and search for HubSpot.
Step 3: Connect HubSpot
Click Connect HubSpot and authorize your HubSpot account via OAuth.
Step 4: Confirm Connection
Once authorized, Apollo will show that HubSpot is successfully connected.
How Sync Configuration: Contacts and Companies
After connecting, let’s configure the sync rules:
Contact Sync Rules
Apollo syncs contacts using the following logic:
- If a contact does not exist in HubSpot → create it
- If a contact already exists → update it
- Primary matching key → Email
Company Sync Rules
Apollo syncs companies using:
- If a company does not exist in HubSpot → create it
- If a company already exists → update it
- Primary matching key → Company Domain
Field Mapping: What Gets Synced?
Apollo can sync multiple enriched fields into HubSpot.
Contact Fields Synced
- First name
- Last name
- Phone number
- Job title
- LinkedIn profile
- Location
Company Fields Synced
- Company name
- Website / domain
- Industry
- Company size
- Revenue (if available)
- Location
Duplicate Prevention Strategy
To avoid duplicates, Apollo and HubSpot rely on:
- Email matching for contacts
- Domain matching for companies
This ensures that even if the same prospect is added again, HubSpot updates the existing record instead of creating a new duplicate.
Testing the Apollo → HubSpot Integration
To confirm the integration is working correctly, run the following tests:
Test 1: Create a New Contact in Apollo
Add a new contact in Apollo and push it to HubSpot.
Verify the contact appears in HubSpot within a few minutes.
Test 2: Update the Contact in Apollo
Update a field such as phone number or job title in Apollo.
Verify the same field updates in HubSpot.
Test 3: Verify Company Sync
Ensure that HubSpot has also created the associated company and matched it using the domain name.
Common Issues and How to Fix Them
