Available actions

## 823 actions your agents can run in LINE

- Create Rich Menu  
Create a rich-menu definition and return its ID. Creation alone does not display it: upload an image, then set it as default or link it to a user.
- Create Rich Menu with Image  
Create a rich-menu definition and upload its JPEG or PNG image in one call. If image upload fails, the newly created definition is deleted automatically. The finished menu must still be set as default or linked to a user to display.
- Delete Rich Menu  
Permanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove.
- Download Message Content Preview  
Download LINE's reduced-size preview image for a retained image or video message whose contentProvider.type is line.
- Get Message Delivery Count  
Get the number of reply, push, multicast, or broadcast messages sent on one UTC+9 calendar date. A result can be unready, unavailable\_for\_privacy, or out\_of\_service instead of containing a count.
- Get Rich Menu  
Get one Messaging API rich-menu definition by ID, including its canvas, tappable areas, and actions.
- Link or Unlink User Rich Menu  
Link or unlink a per-user rich menu. WARNING: LINE can return HTTP 200 even when nothing changed for a nonexistent, deleted, blocked, non-friend, or cross-channel user; success confirms request acceptance, not the assignment effect.
- List Chat Member IDs  
Return one page of member user IDs for a group or legacy room containing the bot. Requires a verified or premium LINE Official Account; room applies only to legacy multi-person chats.
- List Follower IDs  
Return one page of user IDs for friends of the LINE Official Account. This endpoint requires a verified or premium LINE Official Account and excludes blockers, deleted users, and users without profile consent.
- List Rich Menus  
List all rich menus created through the Messaging API. Menus created in LINE Official Account Manager are not included.
- Mark Messages as Read  
Mark all messages through a webhook-issued read token as read. The token must have been received by this exact bot; this operation cannot be undone.
- Set or Clear Default Rich Menu  
Set or clear the Messaging API default rich menu. Setting requires an image-backed rich menu; clearing does not delete the menu and does not clear a default managed in LINE Official Account Manager.
