Held for approval by default (changes and sends)
Held for a person's approval by default. The approval is recorded and the action is sent once, never twice, with 10 seconds to undo. 9 actions.
- Create Rich MenuCreate 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 ImageCreate 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
- Delete Rich MenuPermanently delete a rich menu by ID. Delete only a menu the caller owns or explicitly intends to remove.
- Link or Unlink User Rich MenuLink 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 accept

- Reply to MessageReply with one to five text messages using a single-use token from a LINE webhook. Call this within one minute of receiving the token. If LINE reports an expired, reused, or invalid token, wait for a
- Send Push MessageIrreversibly send one to five text messages from a LINE Official Account to a webhook/API userId, groupId, or roomId. The destination is never a user's visible LINE ID.
- Set or Clear Default Rich MenuSet 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.
- Upload Rich Menu ImageUpload a JPEG or PNG image for a rich menu. An image cannot be replaced for the same rich-menu ID; create a new menu to use another image.
