insert_block
Add a new block as a child to an existing parent block in Logseq. Specify content, optional properties, and position (beginning or end) to organize hierarchical knowledge structures efficiently.
Instructions
Inserts a new block as a child of the specified parent block.
Creates hierarchical content by adding children to existing blocks.
The new block is inserted at the beginning (before=True) or end (before=False)
of the parent's children.
Args:
parent_block_id: The ID of the parent block to insert under.
content: The content of the new block.
properties: Optional properties to set on the new block.
before: Whether to insert at the beginning of children (default: False).
Returns:
Information about the created block.Input Schema
