# Create Subscription

POST https://api.airweave.ai/webhooks/subscriptions
Content-Type: application/json

Create a new webhook subscription.

Webhook subscriptions allow you to receive real-time notifications when events
occur in Airweave. When you create a subscription, you specify:

- **URL**: The HTTPS endpoint where events will be delivered
- **Event Types**: Which events you want to receive (e.g., `sync.completed`, `sync.failed`)
- **Secret** (optional): A custom signing secret for verifying webhook signatures

After creation, Airweave will send HTTP POST requests to your URL whenever
matching events occur. Each request includes a signature header for verification.

Reference: https://docs.airweave.ai/api-reference/webhooks/create-subscription-webhooks-subscriptions-post

## Authentication

- `x-api-key` header (required) — API Key authentication via header

## Servers

- `https://api.airweave.ai` (Production, default)
- `http://localhost:8001` (Local)
