Follow these steps to connect your HighLevel and Follow Up Boss accounts and go live in minutes.
Connect your HighLevel account to HLAPPS so we can securely sync contacts, messages, tags, and automations between platforms. This authorization step must be completed before any other part of the setup will work.
You'll be redirected to HighLevel to grant permission — this takes about 30 seconds and requires admin access to your HL sub-account.
Authorize accountComplete your account setup by submitting your company details. This form configures your integration and links everything together.
Install the HLAPPS embedded app directly inside Follow Up Boss. Once added, you can send messages, schedule follow-ups, and make calls from any contact record — without leaving FUB.
Import our pre-built HighLevel snapshot to automatically create notes in Follow Up Boss whenever a Twilio message error occurs. This helps your team quickly identify and resolve SMS delivery issues without manually monitoring HighLevel.
Recommended if your team actively uses Twilio for outbound SMS campaigns or drip sequences.
Import snapshothlapps_ prefix, or a tag added in HighLevel with the fub_ prefixYou can manage and automate all of these triggers from within your HighLevel Workflows.
Avoiding duplicates is critical. Before syncing, make sure your data is clean. The best way to do this is to push your contacts from Follow Up Boss to HighLevel — this allows the system to map existing contacts across both platforms before creating anything new.
When a contact exists in both platforms, we match them in this order:
Initial sync — pushing all contacts to HighLevel
If you want all your Follow Up Boss contacts in HighLevel, you can add the tag hlapps_transfer to all your contacts to trigger the initial bulk sync. This is completely optional — only do this if you want your entire FUB database pushed to HighLevel.
hlapps_transfer to a large contact list is a significant bulk action. Depending on the size of your database, this process could take many hours to complete. Do not expect contacts to appear in HighLevel instantly — be patient and allow the sync to run in the background.
⛔ FREE TRIAL USERS ARE LIMITED TO 100 CONTACTS. If you exceed 100 contacts, your free trial will automatically end and your card on file will be automatically charged. Do not push more than 100 contacts during the free trial.
How we match contacts between platforms
When an hlapps_ tag is added or an outbound message is sent, we match by GHLID first → then phone number → then email address. If no match is found, a new GHL contact is created automatically.
When a fub_ tag is added, an outbound SMS or email is sent, or a Note is created in GHL, we push the event to FUB and match by GHLID custom field → then phone → then email. No match creates a new FUB contact.
Once everything is set up, run through the following tests to confirm all event triggers are working correctly between Follow Up Boss and HighLevel.
