  Let your LINE Official Account reply automatically based on keywords or
  events. This article covers the three kinds of chatbots, creating a keyword
  chatbot, restriction conditions and tags, and what to watch for when turning
  chatbots on, off or deleting them.
---

By the end of this article you'll be able to create a chatbot that replies automatically when a friend sends a certain keyword, limit when and for whom it triggers, tag members along the way, and turn it off or delete it.

## Before you start

* The workspace needs a connected **LINE Official Account**.
* You need **LINE Chatbot** permission. View Only lets you look; to add, edit, turn on or delete chatbots you need **Editable**, otherwise you'll see "**No edit permission**".
* The Free plan allows up to 10 chatbots per platform. Beyond that you'll see the upgrade prompt.

## Three kinds of chatbots

In the navigation bar, click **LINE** and choose **Chatbot**. The left side groups chatbots into three kinds:

| Kind | When it replies | Where it lives |
|---|---|---|
| **Welcome message bots** | When a friend adds your LINE Official Account | Under **Basic chatbots** |
| **Event-triggered bots** | When something happens, such as a friend sending an image, sticker or location, blocking you, or the **Default Reply** when no other bot answers | Under **Basic chatbots** |
| **Keyword chatbots** | When a friend's text **equals** or **contains** a keyword you set | Under **Keyword chatbots**, organized in folders (up to three levels) |

The screenshot below shows a keyword chatbot folder. The left side lists chatbot kinds and folders; on the right each row is a chatbot with **Chatbot Name**, **Chatbot Status** (a switch), **Trigger Event** and **Trigger Keywords**. The top-right has **AI Generate**, **Display Fields** and **Add**.

![The chatbot list: all chatbots, welcome message bots, event-triggered bots and keyword chatbot folders on the left; on the right, the "Anniversary Sale" folder holds one chatbot "Anniversary sale info" with status off, trigger event Text Message and trigger keyword "anniversary"](https://docs.oakmega.com/en/guide/chatbot/images/line-chatbot-01-list.png)

## Create a keyword chatbot

1. (Recommended) Click "**+**" next to **Keyword chatbots** to add a folder, for example "Anniversary Sale".
2. Click that folder, then click **Add** in the top-right to go straight to the create page. (If you click Add from **All chatbots**, you'll first choose a type under **Select Chatbot Type** and pick a folder.)
3. On the **Bot Settings** tab, enter a **Chatbot Name**.
4. Decide the **Chatbot Status**: it's **on by default** on the create page, so the bot starts replying as soon as you save. Turn it off if you're not ready.
5. Enter keywords in **Trigger Keyword (Equals)** or **Trigger Keyword (Contains)** and press Enter to add each one, up to 20 per field.
6. Switch to the **Edit Message** tab and add the reply messages (up to 5; you can also choose **Template**).
7. Click **Save** in the top-right.

The animation below clicks **Add** in the "Anniversary Sale" folder, enters the chatbot name, and turns the Chatbot Status off.

The screenshot below shows the top of the Bot Settings tab. **Basic Settings** has the chatbot name, status and **Chatbot Time Zone** (the reference time zone for date and time settings), with **Restriction Conditions** below. On the right, **Bot Information** shows the trigger event is Text Message.

Next it scrolls down to Trigger Keyword (Equals), types "anniversary" and presses Enter; the keyword turns into a chip.

Then it switches to the Edit Message tab, clicks **Text** and types the reply. **Message Preview** on the right shows what friends will receive.

Finally it clicks **Save** and returns to the folder, where the new chatbot appears with its status off.

## Restriction conditions and tag settings

The Bot Settings tab lets you limit when and for whom the bot replies, and tidy up tags when it triggers:

| Setting | What it does | Limits |
|---|---|---|
| **Trigger Duration** | Only triggers within a date range: No Limit, Before (inclusive), After (inclusive), Between (inclusive) | Based on the chatbot time zone |
| **Weekly Effective Period** | Only triggers on certain weekdays and hours, such as office hours | |
| **Limit Tag Trigger for Chatbot** | Only applies to members with the chosen tags | Up to 40 tags; choose "Possess all tags simultaneously" or "Possess any one tag" |
| **Exclude Tag Trigger for Chatbot** | Members with the chosen tags won't trigger it | Up to 40 tags |
| **Trigger Environment** | Triggers in LINE friend chats (**Bot**), LINE groups (**Group**) or both (**Bot and Group**) | Some message formats aren't available for groups |
| **Trigger Add Tag**, **Trigger Remove Tag** | Adds or removes tags on the member when triggered | Up to 15 to add, 60 to remove |
| **Share Add Tag** | Adds tags when a member shares this message | Up to 15 |
| **Service center transfer** | Hands the conversation to Service Center after triggering | |

## Turn on, turn off and delete

* **Turn on or off**: flip the Chatbot Status switch right in the list. You'll see "**Chatbot Activated**" or "**Chatbot Deactivated**".
* **Duplicate, move, download trigger records**: click "⋯" at the end of a chatbot's row to **Duplicate**, **Move** it to another folder, or **Download Trigger Records** (recent 10,000 records).
* **Delete**: click "⋯", choose **Delete**, and click **Confirm** in "**Confirm Delete "chatbot name"?**".

The animation below clicks "⋯" on the chatbot we just created, chooses **Delete** and clicks **Confirm**; the chatbot disappears from the list.

When you delete a folder, the confirmation says "**Items in the folder will be deleted as well**", so the chatbots inside are deleted too.

## How it works

* **The create page defaults to on.** As soon as you save, the bot starts replying to real friends. When testing a new bot, turn its status off first and switch it on from the list once you've checked the content.
* **"Equals" is stricter than "Contains".** Contains triggers whenever the keyword appears anywhere in the message; for example the keyword "sale" also fires on "is the sale over?". To respond only to an exact command, use Equals.
* **Richmenus can trigger keywords.** A Richmenu button set to Send text sends the text as the friend, which can trigger a keyword chatbot. See [Set up LINE Richmenus](https://docs.oakmega.com/en/guide/messages/richmenu.md).

## FAQ

### Trigger keyword cannot be empty

A keyword chatbot needs at least one keyword. Type it into Trigger Keyword (Equals) or (Contains) and press Enter.

### Message content cannot be completely empty

The Edit Message tab doesn't have any messages yet. Add at least one message before saving.

### A friend sent the keyword but got no reply

First check that the Chatbot Status is on in the list, then check whether Trigger Duration, Weekly Effective Period, limit or exclude tags, or Trigger Environment rule this friend out.
