How are LINE and HubSpot connected?

Once the Messaging API is enabled on your LINE Official Account, customer messages are sent to n8n. n8n has a built-in HubSpot node that can create or update contacts and create deals and tasks. Field formatting, matching and assignment rules are set to match your process.

Will a repeat inquiry create duplicate contacts?

The workflow first looks for the same person in HubSpot by email or phone, updates the existing contact if found and creates one only if not. Records that look similar but don't match go to a review list for a person to decide; nothing is merged automatically.

Do automated messages keep going after the customer replies?

No. As soon as the customer replies, automated follow-ups stop and the assigned rep is alerted to take over. Automated messages also go only to people who added the account themselves, with a way to opt out.

We don't have engineers. Can we still use this?

Yes. TriloAI handles the build, testing and troubleshooting. You provide access to your LINE Official Account and HubSpot, plus your assignment rules and follow-up times. We also show you how to change simple settings, such as recipients or reminder intervals.

What should we watch for with personal data?

Bring only the fields the workflow needs into HubSpot, and give HubSpot access only to people who need it. Every write and every message sent is logged, so you can see who did what and when. Collection and use must follow Taiwan's Personal Data Protection Act. This is a plain-language summary, not legal advice.

Integration

Send LINE leads to HubSpot with a clear owner and follow-up date

Connecting a LINE Official Account to HubSpot means the inquiries and contact details customers leave on LINE become HubSpot contacts automatically, are assigned to reps by your rules, and trigger reminders when follow-up is due. TriloAI links the two through the LINE Messaging API and n8n's built-in HubSpot node, and actions such as messaging customers can be set to wait for a person's approval. Sending leads to HubSpot alone usually launches in 1–2 weeks; adding assignment and follow-up reminders across several workflows usually takes 3–6 weeks.

Systems involved

LINE Official Account (Messaging API)
HubSpot
n8n integration tool (cloud or self-hosted)
Email or Slack (rep alerts)

Time to launch

A single workflow that sends LINE leads to HubSpot usually launches in 1–2 weeks. Adding assignment, follow-up reminders and LINE confirmations across several workflows counts as cross-system integration and usually takes 3–6 weeks. If you also want AI to answer questions on LINE, it follows the standard Messaging Automation project of about 4–6 weeks.

What runs automatically once connected

Turn LINE inquiries into contacts

Starts when: A customer leaves a name, phone number or email on LINE

1Format the details to match HubSpot fields
2Look for the same person in HubSpot by email or phone; update if found, create if not
3Record LINE as the source, plus the customer's LINE user ID
4Log the key points of the inquiry on the contact

Result: Reps see LINE leads in HubSpot, along with what the customer already asked.

Assign reps by your rules

Starts when: A new LINE lead is created

1Pick the owner by your rules, such as region, product or round robin
2Set the contact owner in HubSpot
3Alert that rep by email or Slack

Result: Every lead has an assigned owner from the start, with no grabbing and no manual sorting by a manager.

Remind reps when follow-up is due

Starts when: A lead passes the agreed time with no follow-up logged

1Create a follow-up task for the owner in HubSpot
2Send the rep a separate email or Slack reminder
3Alert a manager if it is still untouched after a set time

Result: Overdue leads are listed instead of relying on each rep's memory.

Confirm on LINE after the rep approves

Starts when: A rep moves a deal to a stage such as visit booked or quote sent

1The system drafts a confirmation for the customer
2The rep reviews it and approves before it goes out on LINE
3The send time is logged back on the HubSpot contact

Result: Customers get the confirmation on LINE, and HubSpot keeps the record.

What to prepare

Admin access to your LINE Official Account, with the Messaging API enabled
A HubSpot account with super admin or developer tools access to create the connection key
A list of fields to bring into HubSpot, such as name, phone, email and service of interest
Assignment rules: by region, product or round robin, and which reps
Agreed follow-up times, such as how soon a new lead must be contacted

Good to know first

LINE shares only basic details such as the display name, so customers need to give their phone number or email in the chat; leads without them are harder to match to existing HubSpot contacts and are flagged for a person to check.
Only customers who have added your official account as a friend and have not blocked it receive LINE messages; messages you send first count toward the monthly message allowance, which depends on your plan.
Automated follow-ups go only to people who added the account themselves, with a sending cap and a way to opt out; they stop as soon as the customer replies and a rep takes over.
Some HubSpot features depend on your plan, so we check what yours supports before we start.
If this LINE Official Account is already connected to another chatbot or system, we first agree how they work together so the same message isn't handled twice.
