API Reference¶
Observability exposes two REST APIs. Each has a full endpoint reference with request and response schemas.
| API | Purpose | Reference |
|---|---|---|
| Event Ingestion API | POST-only endpoints that receive events from your data estate | Event Ingestion API Reference |
| Observability API | Read and manage projects, journeys, components, runs, rules, and users | Observability API Reference |
Authentication¶
Both APIs authenticate with an API key sent in a request header. API keys are managed per project. See API Keys to create one, and Observability API for the header the Observability API expects.
