What You’ll Need

Account & Access

• ☐ Active FreJun account (all plans supported)
• ☐ Admin access to FreJun dashboard
• ☐ Admin access to your HubSpot portal
• ☐ HubSpot login credentials ready

Technical Prerequisites

• ☐ Stable internet connection
• ☐ Compatible web browser (Chrome or Firefox recommended)
• ☐ FreJun mobile app installed (for accessing synced contacts on mobile)

Data Needed

• ☐ HubSpot portal URL or account email
• ☐ HubSpot admin password (for OAuth authorization step)

⚠️ Plan Note: HubSpot integration is available on all FreJun plans at no additional cost. No upgrade required. See FreJun pricing for full plan comparison.

🔐 Admin Access Required: You must have admin-level permissions in both FreJun and HubSpot to complete the OAuth authorization. Standard users cannot initiate the integration. Ask your HubSpot portal admin to grant Super Admin or App Marketplace access before starting.

Before You Begin: Key Concepts

OAuth Authorization

OAuth is a secure login protocol that lets FreJun access your HubSpot data without storing your password. When you click Connect App, HubSpot opens a permission screen. You approve it once, and FreJun receives a secure token. No API keys to copy or paste.

Contact Sync

Contact sync pushes HubSpot contacts into FreJun so your reps can call them directly from the dialer. This must be explicitly enabled after the initial connection — it does not activate automatically.

Call Activity Logging

Every call made through FreJun is automatically written to the associated HubSpot contact’s activity timeline. This includes call duration, outcome, recording link, and AI-generated call notes.

[DIAGRAM: Flow diagram showing FreJun dialer on the left connecting via OAuth to HubSpot CRM on the right. Arrows labeled “Call Logs,” “Contact Data,” and “Deal Stage Updates” flow bidirectionally between the two platforms. | Alt: FreJun HubSpot bidirectional integration data flow diagram | Filename: frejun-hubspot-integration-flow-diagram.png]

💡 Common Misconception: Many users expect contact sync to be instant after connecting. In practice, initial contact sync completes within 5 minutes of enabling it. Subsequent updates sync in near real-time.

How to Integrate FreJun with HubSpot: Step-by-Step

Phase 1: Connect FreJun to HubSpot (~5 min)

Step 1: Log In to Your FreJun Account

Open your browser and go to frejun.com. Enter your admin credentials and log in.

• Navigate to frejun.com
• Enter your Email and Password
• Click Sign In

✅ Verification: You land on the FreJun main dashboard. Your name or company name appears in the top-right corner.

🔐 Admin Only: You must log in with an admin account. Standard user accounts will not see the Integrations menu in the next step.

Step 2: Navigate to Settings > Integrations

From the FreJun dashboard, access the integrations panel.

• Click the Settings icon (gear icon) in the left sidebar
• Select Integrations from the settings menu

✅ Verification: You see a grid of available integration tiles including HubSpot, Salesforce, Zoho, and others.

💡 Pro Tip: If you don’t see the Integrations option, your account may be set to standard user permissions. Contact your FreJun account owner to elevate your role to Admin.

Step 3: Select HubSpot and Click Connect App

Locate HubSpot in the integrations list and initiate the connection.

• Scroll through the integrations grid or use the search bar to find HubSpot
• Click the HubSpot tile to open its detail panel
• Click the Connect App button

✅ Verification: Your browser redirects to HubSpot’s OAuth authorization screen. You should see HubSpot’s login page or permission grant screen.

⚠️ Plan Note: Available on all FreJun plans. No upgrade required.

💡 Pro Tip: If the redirect doesn’t happen, disable any browser pop-up blockers and try again. Chrome with no extensions is the most reliable environment for this step.

Step 4: Log In to HubSpot and Authorize Access

Complete the OAuth handshake by granting FreJun permission to your HubSpot portal.

• Enter your HubSpot email and password on the HubSpot login screen (skip if already logged in)
• Select the correct HubSpot portal if you manage multiple accounts
• Review the permissions FreJun is requesting (contacts, deals, activities)
• Click Grant Access or Connect App

✅ Verification: HubSpot displays a confirmation message and redirects you back to FreJun automatically.

🔐 Admin Only: You must have HubSpot Super Admin or App Marketplace permissions to grant access. If you see an error saying “You don’t have permission to install apps,” contact your HubSpot portal admin.

Step 5: Confirm the Integration Is Active

Back in FreJun, verify the connection succeeded.

• You are automatically redirected to Settings > Integrations in FreJun
• Locate the HubSpot tile
• Confirm the button now reads Disconnect (not Connect App)

✅ Verification: The Disconnect button is visible on the HubSpot tile. A green “Connected” status badge may also appear.

✅ Phase 1 Complete. FreJun is now authorized to communicate with your HubSpot portal. Time so far: ~5 minutes.
Next: Configure contact sync and call logging settings.

Phase 2: Enable Contact Sync and Call Logging (~5–10 min)

Step 6: Enable Contact Sync

Activate the sync so HubSpot contacts appear in FreJun’s dialer.

• Click the HubSpot tile in Settings > Integrations
• Toggle Contact Sync to On
• Choose sync direction: HubSpot → FreJun (recommended for initial setup)
• Click Save Settings

✅ Verification: Within 5 minutes, HubSpot contacts appear in your FreJun dialer contact list.

💡 Pro Tip: Enable contact sync during off-peak hours if your HubSpot portal has more than 10,000 contacts. Large initial syncs can take up to 15 minutes.

Step 7: Configure Call Logging Preferences

Set how FreJun writes call data back to HubSpot.

• In the HubSpot integration settings panel, scroll to Call Logging
• Enable Auto-log calls to HubSpot activity feed
• Enable AI call notes if you want AI-generated summaries attached to each log
• Enable Deal stage auto-update to let call outcomes trigger HubSpot deal stage changes
• Click Save Settings

✅ Verification: Make a test call (covered in Section 6). The call appears in the HubSpot contact’s activity timeline within 60 seconds.

✅ Phase 2 Complete. Contact sync is active and call logging is configured. Total time: ~10–15 minutes.

Configuring the HubSpot Integration for Your Team

Call Logging Settings

Control exactly what data FreJun writes to HubSpot after each call.

• Go to Settings > Integrations > HubSpot > Call Logging
• Adjust each setting based on your team’s workflow

Setting	Default	Recommended	Why Change
Auto-log calls	Off	On	Eliminates manual logging for all reps
AI call notes	Off	On	Saves 3–5 min per call in note-taking
Deal stage auto-update	Off	On	Keeps pipeline accurate without rep input
Contact sync direction	Manual	HubSpot → FreJun	Ensures reps always call current contacts

Contact Sync Settings

Manage which HubSpot contacts sync to FreJun and how frequently.

• Navigate to Settings > Integrations > HubSpot > Contact Sync
• Set filters to sync only relevant contact lists (e.g., active leads, open deals)
• Set sync frequency to Real-time for high-velocity sales teams

Setting	Default	Recommended	Why Change
Sync frequency	Manual	Real-time	Reps always see latest contact data
Contact filter	All contacts	Active leads only	Reduces noise in dialer
Mobile app sync	Off	On	Enables calling from FreJun mobile app

Custom Field Mapping

Map HubSpot custom properties to FreJun call data fields.

• Go to Settings > Integrations > HubSpot > Field Mapping
• Click Add Mapping
• Select a FreJun field (e.g., “Call Outcome”) and map it to a HubSpot property (e.g., “Last Call Result”)
• Click Save

💡 Pro Tip: Use FreJun’s Auto-Match feature first. It maps standard fields automatically. Only manually map custom fields that auto-match misses.

Connecting with Other Tools

Connecting with Salesforce

FreJun also offers a native Salesforce integration with the same OAuth flow. Visit the FreJun integrations page for full setup steps.

Connecting with Zoho CRM

Zoho CRM connects via Settings > Integrations > Zoho. The process mirrors the HubSpot steps above.

Connecting with Other Tools via Zapier

For tools not natively supported, use Zapier to connect FreJun to 1,000+ apps.

Integration	Available	Setup Time	Notes
HubSpot	✅ Native	5 min	Full call logging + contact sync
Salesforce	✅ Native	5 min	See integrations page
Zoho CRM	✅ Native	5 min	OAuth-based
Zapier	✅ Supported	10 min	1,000+ app connections

Test That the HubSpot Integration Works

Test 1: Verify Contact Sync

Confirm HubSpot contacts are visible in FreJun.

• Open the FreJun dialer
• Search for a contact that exists in HubSpot (e.g., a known lead’s name)
• Confirm the contact appears with their HubSpot data (name, company, phone number)

✅ Success: Contact appears in FreJun with correct HubSpot data
❌ Failure: Contact not found → Check that Contact Sync is enabled and 5 minutes have passed → See Troubleshooting

Test 2: Verify Call Logging to HubSpot

Confirm calls made in FreJun appear in HubSpot’s activity feed.

• Make a short test call to a HubSpot contact using FreJun
• End the call and wait 60 seconds
• Open HubSpot CRM and navigate to that contact’s record
• Check the Activity tab for the logged call

✅ Success: Call appears in HubSpot activity feed with duration, outcome, and AI notes
❌ Failure: No call logged → Verify Auto-log calls is enabled in FreJun → See Troubleshooting

Testing Checklist

• ☐ HubSpot contacts visible in FreJun dialer
• ☐ Test call appears in HubSpot activity feed within 60 seconds
• ☐ AI call notes attached to the logged activity
• ☐ Deal stage updated if call outcome was set (if feature enabled)
• ☐ FreJun mobile app shows synced contacts

Troubleshooting Common Issues

Issue: “Disconnect” Button Not Appearing After Authorization

Symptoms: Returned to FreJun but HubSpot tile still shows Connect App. No confirmation message after HubSpot authorization.

Common Causes: Browser pop-up blocker interrupted the OAuth redirect; HubSpot session timed out during authorization; insufficient HubSpot permissions (not Super Admin).

Solution:

• Clear browser cache and retry: Press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac), clear cookies and cached data, retry from Step 3.
• Verify HubSpot permissions: Log in to HubSpot as Super Admin, go to Settings > Users & Teams > your user, confirm App Marketplace Access is enabled, retry the connection.

✅ Expected Result: HubSpot tile shows Disconnect button after successful retry.

💡 Prevention: Always use Chrome with extensions disabled for the initial OAuth connection.

Issue: HubSpot Contacts Not Appearing in FreJun

Symptoms: FreJun dialer shows no contacts or only old contacts. Search returns no results for known HubSpot contacts.

Common Causes: Contact Sync toggle is disabled; initial sync still in progress (large contact lists take up to 15 minutes); contact filter excludes the contacts you’re searching for.

Solution:

• Enable Contact Sync: Go to Settings > Integrations > HubSpot, toggle Contact Sync to On, wait 5 minutes and refresh the FreJun dialer.
• Check contact filters: In the HubSpot integration settings, review active filters. Temporarily set filter to All Contacts to test. Re-apply specific filters after confirming sync works.

✅ Expected Result: HubSpot contacts appear in FreJun dialer within 5–15 minutes.

💡 Prevention: Enable contact sync immediately after connecting. Don’t wait until reps need to make calls.

Issue: Calls Not Logging to HubSpot Activity Feed

Symptoms: Calls made in FreJun don’t appear in HubSpot contact records. HubSpot activity feed shows no recent call entries.

Common Causes: Auto-log calls toggle is disabled in FreJun; call was made to a contact not synced from HubSpot; HubSpot API rate limit temporarily exceeded.

Solution:

• Enable auto-logging: Go to Settings > Integrations > HubSpot > Call Logging, enable Auto-log calls to HubSpot activity feed, save settings and make a new test call.
• Check contact association: Confirm the contact you called exists in HubSpot. Verify the phone number in FreJun matches HubSpot exactly (including country code).

✅ Expected Result: Calls appear in HubSpot activity feed within 60 seconds of call completion.

💡 Prevention: Run the testing checklist in Section 6 immediately after setup to catch logging issues before your team starts calling.

Best Practices for FreJun HubSpot Integration

1. Enable AI Call Notes from Day One

Why: AI-generated call summaries save each rep 3–5 minutes per call. For a 10-rep team making 50 calls/day, that’s 25–50 hours saved weekly.

Do this: Enable AI call notes in Settings > Integrations > HubSpot > Call Logging. Train reps to review and edit AI notes within 10 minutes of each call for accuracy.

Don’t do this: Don’t rely solely on AI notes for complex deals — always add manual context for high-value opportunities.

2. Use Deal Stage Auto-Update for Pipeline Accuracy

Why: Manual deal stage updates are forgotten 40% of the time. Automating this keeps your HubSpot pipeline accurate without adding rep workload.

Do this: Map FreJun call outcomes (e.g., “Interested,” “Not Interested,” “Follow-up Scheduled”) to HubSpot deal stages. Review the mapping quarterly to align with your sales process.

Don’t do this: Don’t map every call outcome to a deal stage change — only map outcomes that genuinely indicate pipeline movement.

3. Filter Contact Sync to Active Lists Only

Why: Syncing all HubSpot contacts (including unsubscribed or closed-lost) clutters the FreJun dialer and slows search.

Do this: Create a HubSpot active list (e.g., “Open Leads + Active Deals”) and sync only that list to FreJun. Update the list criteria monthly.

Don’t do this: Don’t sync your entire HubSpot database if it contains more than 50,000 contacts without filtering.

4. Test the Integration After Any HubSpot Portal Changes

Why: HubSpot portal migrations, permission changes, or app marketplace updates can silently break the OAuth token.

Do this: Run the testing checklist (Section 6) after any HubSpot admin changes. Set a monthly calendar reminder to verify a test call logs correctly.

Don’t do this: Don’t assume the integration is working because it worked last month — verify proactively.

5. Use the FreJun Mobile App for Field Sales Teams

Why: Synced contacts are accessible via the FreJun mobile app, enabling field reps to call HubSpot contacts and log activities from anywhere.

Do this: Install the FreJun mobile app on all field rep devices. Enable Mobile App Sync in the HubSpot integration settings.

Don’t do this: Don’t expect synced contacts to appear on the FreJun web dashboard — mobile app access is the supported path for contact browsing.

How FreJun Outperforms Alternatives

1. Included on All Plans — No Add-On Fees

FreJun includes HubSpot integration on every plan, including Starter. No upgrade required, no per-user add-on fees.

• JustCall: HubSpot integration requires the Pro plan ($49/user/month minimum)
• Kixie: Integration available but requires manual API key setup — no OAuth
• RingCentral: HubSpot integration is a paid add-on ($10/user/month)

FreJun savings: $1,200/year for a 10-user team compared to RingCentral’s add-on pricing. See our full pricing page to compare plans.

2. AI Call Logging with Deal Stage Automation

FreJun’s AI automatically logs calls, generates summaries, and updates HubSpot deal stages based on call outcomes. Competitors require manual input or third-party tools to achieve the same result.

• Reps spend zero time on CRM data entry after calls
• Pipeline accuracy improves without manager enforcement
• Sales leaders get real-time visibility into call activity

Competitors’ gaps: JustCall logs calls but does not auto-update deal stages. Kixie has no native AI call notes — requires Gong or Chorus integration.

3. Setup in Under 5 Minutes via OAuth

FreJun uses OAuth — no API keys, no developer involvement, no documentation hunting. “Setup took 3 minutes” — G2 review, January 2026, 50-employee sales team. 87% of FreJun users complete the integration in under 10 minutes.

Frequently Asked Questions

How long does the FreJun HubSpot integration take to set up?

Most users complete setup in 5–15 minutes. The OAuth connection itself takes under 5 minutes. Configuring call logging and contact sync adds another 5–10 minutes. FreJun’s 87% of users finish the entire process in under 10 minutes. The maximum reported time is 45 minutes, typically when troubleshooting permission issues.

How do I sync custom fields between FreJun and HubSpot?

Go to Settings > Integrations > HubSpot > Field Mapping. Click Add Mapping, select a FreJun field, and map it to your HubSpot custom property. Use the Auto-Match feature first — it handles standard fields automatically. Only manually map fields that auto-match doesn’t cover. Custom field mapping is available on all FreJun plans.

Does FreJun work with HubSpot’s free CRM?

Yes. FreJun integrates with all HubSpot tiers, including the free CRM. The OAuth authorization process is identical regardless of your HubSpot plan. Call logging, contact sync, and AI notes all function with HubSpot Free. Advanced features like deal stage auto-update require HubSpot deals to be enabled, which is available on HubSpot Free.

Is the FreJun HubSpot sync bidirectional?

Partially. Call data and activity logs flow from FreJun into HubSpot automatically. Contact data syncs from HubSpot into FreJun when contact sync is enabled. Changes made directly in HubSpot sync to FreJun, but changes made in FreJun do not automatically update HubSpot contact records. This is a known limitation documented in FreJun’s knowledge base.

Why are my HubSpot contacts not showing in FreJun after connecting?

Contact sync must be enabled separately after the initial OAuth connection. Go to Settings > Integrations > HubSpot, toggle Contact Sync to On, and wait 5 minutes. If contacts still don’t appear, check your contact filter settings — an overly narrow filter may be excluding the contacts you’re looking for. Large contact lists (10,000+) can take up to 15 minutes for the initial sync.

Can I undo the HubSpot integration?

Yes. Go to Settings > Integrations > HubSpot > Disconnect. This stops all future syncing but does not delete historical call logs already written to HubSpot. Existing HubSpot contact records remain unchanged. You can reconnect at any time using the same OAuth flow without data loss.

Is my HubSpot data secure when connected to FreJun?

Yes. FreJun uses 256-bit AES encryption for all data in transit and at rest. FreJun is SOC 2 Type II certified and GDPR compliant. Your HubSpot credentials are never stored by FreJun — only a secure OAuth token is retained. See the FreJun security page for full details.

What if I don’t have admin access to HubSpot?

You need HubSpot Super Admin or App Marketplace access to authorize the integration. Contact your HubSpot portal admin and ask them to either complete the authorization themselves or grant you the necessary permissions. In HubSpot: Settings > Users & Teams > select your user > enable App Marketplace Access. Once permissions are granted, return to Step 3 of this guide.

How to sync contacts between HubSpot and FreJun automatically?

Enable real-time contact sync in Settings > Integrations > HubSpot > Contact Sync. Set sync frequency to Real-time and choose HubSpot → FreJun as the sync direction. New contacts added to HubSpot will appear in FreJun’s dialer within minutes. For best results, create a HubSpot active list of your target contacts and sync only that list to keep the FreJun dialer clean.

What to Do Next

You’ve successfully connected FreJun to HubSpot, enabled contact sync, and configured automatic call logging. Here’s how to maximize the value of your setup:
