Create a LINE Messaging API Channel

What is a Channel? (Is it different from an OA?)

This is easy to mix up. The OA is the clinic channel that patients actually see. The Channel is the API credential container you create in the Developers Console.

Analogy: the OA is the storefront (patients walk in and send messages). The Channel is the back-door key (clinic staff come in via the API to handle messages).

You need both, and when they are created under the same Business ID they link automatically.

The Provider concept

The top-level group in the Developers Console is the Provider. You can create multiple Channels inside a Provider.

• Provider = the company (e.g. our clinic group)
• Channel = an individual communication channel (Messaging API, LINE Login, etc., by type)
• If you have multiple OAs, each OA needs its own separate Messaging API Channel

Create a Provider

1. Go to developers.line.biz/console → sign in with the same Business ID you use for OA Manager
2. On first entry, accept the terms and enter your developer details (name · company · contact)
3. Click Create a new provider
4. Provider name: your company name (not shown to patients — internal use only)
   • e.g. Our Clinic Group or Aura Group
5. Create

Create a Messaging API Channel

1. Open the Provider you just created
2. Click the Create a Messaging API channel card
3. Enter the details:
   • Channel type: Messaging API (already selected)
   • Provider: the Provider you created above
   • Channel icon: clinic logo (optional, can be changed later)
   • Channel name: recommended to match the OA
   • Channel description: a one-line description
   • Category: Hospital / Clinic
   • Subcategory: Hospital / Beauty Clinic, etc.
   • Email address: operations email
   • (Optional) Privacy Policy URL, Terms of Use URL
4. Accept the terms (LINE Developer Agreement + LINE Official Account API Terms)
5. Create

Confirm the automatic link to your OA

If you created it under the same Business ID, the Messaging API Channel links automatically to your existing OA.

1. Channel console → Messaging API tab
2. If the OA name appears at the top, the link is working
3. The Channel ID + Channel Secret + Channel Access Token shown here are what you use to connect the CRM

Frequently asked questions

Q. I created the wrong Channel

You can delete it via Channel settings → Delete this channel. Note that deleting it immediately breaks the Webhook and invalidates the token. You will need to create a new Channel and re-register it in the CRM.

Q. My OA doesn't appear (it didn't link automatically)

Check that you are signed in with the same Business ID on both the Developers Console and OA Manager. If you created it with a different ID, manual linking is required and the process is complicated — creating a new one with the same ID is faster.

Q. Do I also need to create LIFF and LINE Login?

If you only need the Messaging API integration, don't create LIFF/LINE Login channels. They are separate authentication flows and the CRM does not use them.

Q. What's next?

1. Continue to the actual integration steps in the LINE connection guide — issue the Channel Secret + Access Token → register the Webhook URL → enter them in the CRM
