## Welcome

The Gateway API provides OTLP/HTTP endpoints for ingesting OpenTelemetry traces.

## Authentication

All trace ingestion endpoints require authentication via OAuth2 bearer token in the Authorization header:

```
Authorization: Bearer <your_oauth2_token>
```

Obtain your token from the [OAuth API](/api-reference/oauth/introduction) using:

* API key and secret with `write:traces` permission
* `grant_type` = `client_credentials`
* `audience` = `https://gateway-api.unomiq.com`.

## Base URL
