Open Collective vs TikTok

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.

TikTok for Developers bundles several OAuth-based kits under one app registration — Login Kit for authentication, Display API for a user's own public videos, and Content Posting API for publishing on their behalf — all issued through open.tiktokapis.com. More sensitive scopes require TikTok's app review before going live, and a separate Research API exists for qualified academics to query public data.
