Facebook vs Open Collective

Meta's Graph API is the single HTTP interface behind Facebook Login, Page management, and Social Plugins, exposing versioned endpoints under graph.facebook.com that read and write data about people, Pages, and Groups once a user grants OAuth permissions. Most scopes that touch another person's data or a business Page require Meta's app review process before they work outside development mode, and the same Graph API infrastructure also underlies Instagram's Business API stack.

Open Collective's GraphQL API (v2) queries collectives, expenses, transactions, and members for the platform's transparent nonprofit/open-source funding model, and public collective data is readable with no authentication at all. Its own docs flag the older REST API as still running but no longer developed, pointing new integrations at the GraphQL surface and a companion PDF service (for receipts and invoices) that accepts either a personal token or an OAuth bearer token. A personal access token, not a full OAuth app-review flow, is the documented way to authenticate for private or write access.
