Create document

Create a markdown/text DOCUMENT in a business's library.

This is the create endpoint for the same documents that list_files, get_file, update_file, and delete_file operate on (the create_library_file name is kept for backwards compatibility). It does NOT upload an image or video — for binary media use upload_media.

Documents are stored as resources and can be used as context for post generation. Use this to push blog posts, notes, or any written content.

Send an Idempotency-Key header to make a retry safe (a resend with the same key returns the original file instead of creating a duplicate).

Errors: 400 invalid_request: The file could not be created (e.g. bad path or content). 400 invalid_value: The business_id is not a valid UUID. 401 authentication_required: API key or token is missing, invalid, or revoked. 403 permission_denied: Your plan does not include API access, or this business is not in your org. 404 resource_not_found: No business with that ID exists. 422 IDEMPOTENCY_KEY_CONFLICT: The Idempotency-Key was reused with a different body. 429 rate_limit_exceeded: You sent too many requests this minute.
