LINE

Enable the LINE connector in your fastn dashboard, then let each customer authenticate their own LINE account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LINE client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Yes. Every connection is scoped to the individual customer, so each authorises their own LINE account and only ever sees their own messages, conversations and participants. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.

Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent drafts and sends a reply to an inbound message within governed permissions.

fastn does. When LINE changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.

Yes. Every customer authorises their own LINE account, so messages, meetings and notifications originate from their workspace under their permissions. You never proxy through a shared account, which also means a customer revoking access affects only their own connection.

Sends are deduplicated per event, so a retry after a network failure does not post the same message twice into a channel people are reading.

A common starting point: connect their own LINE official account so your product messages their users from their own account. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LINE does not change your per-connector cost. You can start free with 3 connected accounts.
