# Developer integrations

> Build on the platform using OAuth apps, webhooks, and API keys—learn how to register clients, subscribe to events, and authenticate server-side requests.

Developer integrations are for teams building custom workflows or connecting internal systems.

Use OAuth for user-delegated access, webhooks for reactive automation, and API keys for secure server-to-server calls.
