LINE Connection

The LINE connection lets you publish DailyPlay streams inside LINE using a LIFF or LINE MINI App channel. Players open a permanent LINE link and play your campaign in LINE — no Messaging API or channel secrets required.

Prerequisites

Section titled “Prerequisites”
Requirement Where to find it
LINE Developers account LINE Developers Console
LIFF app (or LINE MINI App channel) LINE Developers Console → your provider → LIFF / MINI App
Public LIFF ID Shown on the LIFF (or MINI App) settings page — e.g. 1234567890-AbCdEfGh

Setting Up the Connection

Section titled “Setting Up the Connection”
  1. Go to Connections from the main navigation
  2. Click Add Connection and choose LINE (LIFF / MINI App)
  3. Enter:
    • LIFF ID (required) — your public LIFF ID only; do not paste a channel secret or access token
    • Link type — Classic LIFF (recommended) or LINE MINI App
    • LINE Basic ID (optional) — e.g. @yourbrand
    • Official Account page URL (optional) — e.g. https://page.line.me/…
  4. Save the connection

Configure the Endpoint URL in LINE

Section titled “Configure the Endpoint URL in LINE”

In the LINE Developers Console, set your LIFF (or MINI App) Endpoint URL to:

https://app.dailyplay.ai/?liff_id=YOUR_LIFF_ID

Replace YOUR_LIFF_ID with the same LIFF ID you entered in DailyPlay. The liff_id query parameter is required so DailyPlay can initialize LIFF before opening the stream.

Then ensure the LIFF app is Added (or publish your MINI App channel) in the LINE Developers Console.

Publishing a Stream to LINE

Section titled “Publishing a Stream to LINE”

Once an active LINE connection exists for your organization:

  1. Open the stream you want to publish
  2. Open the Share options
  3. Use the Publish to LINE panel:
    • Copy the LINE permanent link
    • Follow the setup checklist (Endpoint URL, LIFF/MINI App published, link added to OA)
Section titled “Permanent link format”
Link type URL pattern
Classic LIFF https://liff.line.me/{liff_id}/stream/{org-slug}/{stream-slug}
LINE MINI App https://miniapp.line.me/{liff_id}/stream/{org-slug}/{stream-slug}
Section titled “Add the link to your Official Account”

Put the permanent link in your LINE Official Account rich menu or rich message so followers can open the stream in one tap.

Share on LINE

Section titled “Share on LINE”

From a stream (or game) share panel you can also use Share on LINE:

  • Mobile — Opens the LINE share sheet with a pre-filled message
  • Desktop — Copies the message so you can paste it into LINE

When a LINE connection is active, the shared message uses the permanent LIFF/MINI App URL. Otherwise it uses the normal stream (or game) URL.

How It Works

Section titled “How It Works”
  1. A player opens the permanent LINE link (from your rich menu, a rich message, or a shared message)
  2. LINE loads DailyPlay with your configured Endpoint URL and liff.state
  3. DailyPlay initializes LIFF, then opens the stream path
  4. The player plays the stream inside LINE

If LIFF initialization fails, or the player opens a normal https://app.dailyplay.ai/stream/… link inside LINE’s in-app browser, the stream still loads as a regular web page.

Managing the Connection

Section titled “Managing the Connection”
  • Edit — Update LIFF ID, link type, Basic ID, or OA page URL from Connections
  • Enable / Disable — Toggle the connection without deleting it (disabled connections hide the Publish to LINE panel)
  • Delete — Permanently remove the LINE connection from your organization

Troubleshooting

Section titled “Troubleshooting”

Publish to LINE panel does not appear

Section titled “Publish to LINE panel does not appear”
  • Confirm you created a LINE (LIFF / MINI App) connection (not a webhook)
  • Ensure the connection is enabled
  • Open a stream share panel — permanent publish is stream-only

Stream opens as a blank page in LINE

Section titled “Stream opens as a blank page in LINE”
  • Verify the Endpoint URL is exactly https://app.dailyplay.ai/?liff_id=YOUR_LIFF_ID
  • Confirm the LIFF ID in DailyPlay matches the LIFF app in the LINE Developers Console
  • Ensure the LIFF app is Added (or the MINI App channel is published)
Section titled “Permanent link opens but stream does not load”
  • Check that the org slug and stream slug in the URL are correct
  • Confirm the stream is published / playable in DailyPlay
  • Try opening the normal stream URL in a regular browser to isolate LINE-specific issues

Share on LINE copies a message instead of opening LINE

Section titled “Share on LINE copies a message instead of opening LINE”
  • On desktop, LINE’s share URL is not supported — DailyPlay copies the message for you to paste
  • On mobile, the LINE share sheet should open automatically

Limitations

Section titled “Limitations”
  • No LINE Messaging API, push messages, or bot webhooks in this integration
  • Channel secrets and access tokens are not stored — paste the public LIFF ID only
  • LINE cannot be attached as a stream event sink (unlike Braze, Zapier, or webhooks)
