Notion Marketplace
Notion Labs, Inc.
Integrations and widgets that extend Notion pages, databases, and workspaces.
Services that sync or read/write data through the platform’s APIs rather than embedding UI.
21 marketplaces in this directory match this tag.
A connector integrates through the platform’s APIs — syncing records, reading and writing data, reacting to webhooks — without rendering UI inside the host. It is the workhorse surface of CRM, cloud, and automation marketplaces, and the natural shape when your product already has its own interface.
Connectors authenticate with OAuth 2.0 for multi-tenant apps or API keys and personal access tokens for single-account use, and they live or die on rate limits and data-model fidelity. On iPaaS platforms a single published connector becomes usable across the whole ecosystem — publish once, reach everywhere.
