Publishing to LINE

Learn how to configure the integration with LINE. Let users of LINE message your bot and get quick answers.

To publish your chatbot to LINE, you will need to create a Messaging API channel.

Tip: Please refer to these instructions for more details on channel creation.

Note: For using a third party integration component, requests and end-user data are sent to both Progress and the third party. Also, you may be required by the third party to have a valid account with such third party. The third party’s terms of service, SLA, pricing, and quotas are applicable for using a third party integration component.

Create a Messaging API provider

First, you have to open the LINE Developers Console and create a Provider. The service is provided free of charge for LINE business accounts.

Create a Messaging API channel

In your newly created provider you need to create a new Messaging API channel.

Obtain your Messaging API channel’s credentials

From the Basic settings of your newly created channel you should be able to retrieve its Channel secret. In the Messaging API tab of your channel scroll down to Channel access token and issue a Long-lived channel access token

Create a new channel in NativeChat

Open the Publishing section of your NativeChat bot.
Click the Add button for LINE to open the Add LINE configuration form.
Provide the Channel secret and Long-lived channel access token you have obtained from your Messaging API channel.
Click the Add configuration button. You will receive a Webhook URL that you will need to enter in the Messaging API tab of your LINE channel in the LINE Developers Console.

Configure the Webhook URL

Open the Messaging API tab of your LINE channel in the LINE Developers Console. Next locate the Edit button below the Webhook URL title in the Webhook settings section. Click the Edit button and paste the endpoint URL that was generated by NativeChat, and click the Update button. Afterwards locate the Use webhook switch and flip it. This will connect your LINE bot channel with NativeChat and you should now be able to chat with the bot.

Remove the bot’s automatic reply

After you’ve done all the steps above you’ll notice the bot immediately responds with an automatic response stating Unfortunately, this account isn’t set up to reply directly to messages. In order to disable this you need to head to the Messaging API tab of your LINE channel in the LINE Developers Console. Locate Auto-reply messages and click the green Edit button on the right side. In the newly opened tab locate Auto-response and click on the Disabled radio button next to it.

Test your bot

With LINE for Android or iOS

To add your bot as a contact to your LINE account you will have to:

Open the Messaging API tab of your LINE channel in the LINE Developers Console.
On your mobile device open the LINE application.
In the LINE mobile application navigate to Home and then click Add friends -> QR code
Scan the QR code displayed in the Messaging API tab of your LINE channel

Known issues

The LINE channel is still in Beta and is missing some of the features available in the other channels that NativeChat provides.

Limitations

Multi-select is not supported.
Quick reply, Location picker, Third-party Authentication, Date picker, Single-select, and Carousel are only supported for the LINE mobile application (iOS and Android).

Things to consider

After a user selects an item using the UI for Single-select or Date-picker they won’t see the actual response in the chat. This behavior cannot be changed and you may want to add some additional steps to your cognitive flow in order to display the chosen value.
