[ -n "$NOTION_INTEGRATION_KEY" ] && echo "NOTION_INTEGRATION_KEY is set" || echo "NOTION_INTEGRATION_KEY is NOT set"If it’s missing, ask the user to provide it (or connect a Notion integration) before proceeding:
- NOTION_INTEGRATION_KEY: Notion integration secret (starts with
ntn_...)
Also confirm the integration has been shared with the target page/database in Notion.

}' | jq .Tips / gotchas
- Sharing is required: even with a valid key, the integration can’t see a page/database until it has been shared with the integration in the Notion UI.
- Rate limits: keep requests small; for large pages, create the page first and then append blocks in batches.
- IDs format: Notion IDs may be returned with dashes; both dashed and non-dashed forms typically work in API calls.
