# Connect Notion with an internal integration token

`POST /v1/integrations/notion/connect`

Connect a Notion workspace using a customer-created internal integration token (no OAuth).

## Request body

- NotionManualConnectBody — Request body for connecting Notion with a customer-created internal integration token.
  - `access_token` string, required — Notion internal integration token (ntn_… or secret_…)
  - `store_name` string, nullable — Optional ingestion store name
  - `store_config` IntegrationStoreConfig — Store and file configuration chosen when connecting a data source. Applied to the ingestion store when the connector creates it and to every imported file. The defaults (contextualization on, high-quality ingestion) give the best retrieval quality and downstream availability. A pre-existing store keeps its own configuration; only the ingestion mode still applies to newly imported files.
    - `metadata_contextualization` boolean — Contextualize chunks with the connector's curated metadata fields
    - `file_contextualization` boolean — Generate an LLM context for each chunk situating it within the full document
    - `ingestion_mode` 'fast' | 'high_quality' — Strategy for adding a file to a store.
