# API Reference

> Auto-generated reference from the live OpenAPI spec.

The endpoints under this tab are generated from the live OpenAPI
spec at `https://api.yotel.in/openapi.json`. They update as we ship.

If a route shown here differs from what you see on the live API, it
likely means we deployed a docs build against a newer spec. Refresh
the page and check the `info.version` at the spec URL.

## Base URL

```
https://api.yotel.in
```

Regional: GCP Mumbai (`asia-south1`). No multi-region routing yet.

## Authentication

Every request on the `/api/v1/*` surface:

```
Authorization: Bearer yt_<env>_<secret>
```

See [Authentication](/authentication) for the full details.

## Try it in the playground

Each operation below has an interactive "Try it" panel. Paste your
`yt_test_…` key, tweak the request body, hit Run. Responses show the
real HTTP status + headers (including rate-limit).

<Warning>
  The playground uses **your real API**. A test-key "Try it" on
  `POST /api/v1/campaigns` creates a real row in your tenant's
  database. Use `yt_test_…` keys only.
