How do I connect my gym's LINE, and why does nothing arrive?

Connecting LINE costs nothing and needs no upgrade. Your members link their own LINE from their space, and the automatic messages you switched on reach them there: booking confirmations, receipts, class reminders, membership changes.

What is paid is the marketing side, not the plumbing. Writing message templates, sending one by hand and sending a group message belong to the Pro plan. Answering someone who wrote to you first is free, on purpose: receiving a message with nowhere to answer it is worse than not receiving it.

Path: Settings › Integrations › LINE.

A LINE Login channel identifies a member when they tap Connect your LINE. A Messaging API channel sends and receives. They do different jobs and neither replaces the other, which is why there are four boxes and not two.

Create both under the SAME provider in the LINE developer console. Two providers is the mistake that costs an afternoon: everything looks configured and members are recognised as strangers.

In your Messaging API channel, under Basic settings, there is a Linked LINE Official Account. If it is empty, LINE never offers Add as friend while a member signs in.

LINE only lets you write to people who added your Official Account as a friend. Signing in is not adding. So with that box empty, members connect happily, your screen says connected, and not one message is ever delivered. No error appears anywhere.

The Connected pill only looks at two of the four boxes: the Login Channel ID and the Messaging API access token. A gym can be marked connected with no channel secret for the Messaging API.

That secret is what proves an incoming message really comes from LINE. Without it, replies and blocks arrive at your server and are thrown away, and you keep writing into a void.

The member does it, from their own space: a Connect your LINE line sits at the top until they link, and the same button is repeated in My profile. At the front desk you can also hand them your phone: Link your account on their profile shows them a screen where one tap does it.

If they are not in front of you, open their profile and press Send connection link. It emails them the link. That needs an email address on their file; without one the row says so instead of offering a dead button.

A member who never linked is skipped in silence by every automatic message. Nothing is logged on your screen, because from the software's point of view nothing failed.

A member who linked and then BLOCKED your Official Account is different, and it is visible: the integration screen shows an Unreachable on LINE count with a See who button that filters your member list.

Replies your team types inside the LINE app never come back into the Inbox. LINE forwards what the member sends, never what you send from the LINE app. Answer from MoveMembers and the whole conversation stays in one place.

Three places do it: the member from their own space, you from the member row menu, and you from the LINE line on their profile. All three clear the link and nothing else.

Nothing is revoked on LINE's side. The person is still a friend of your Official Account, and they are told nothing. To message them again they have to go through the link once more.
