# Create notification subscription

POST /api/notifications/subscriptions/subscribe
Content-Type: application/json

Link an event type to a notification channel

Reference: https://docs.ellaworks.ai/api-reference/ellaworks-prm-api/notifications/subscribe

## Authentication

- `X-API-Key` header (required) — API key supplied via the X-API-Key header. Takes precedence over bearerApiKey when both are present. Listed only on operations that actually accept a key.
- `Authorization` header (bearer token, required) — Same organization API key supplied as a Bearer token in the Authorization header (Authorization: Bearer \<key>). Compatible with OpenAI-SDK-standard clients. Accepted wherever this scheme is listed on the operation — not every endpoint; if both X-API-Key and Authorization: Bearer are present, X-API-Key wins.
- `Authorization` header (bearer token, required) — Supabase session JWT from a signed-in browser session, supplied as Authorization: Bearer \<jwt>. This is what the web app sends. It shares the Authorization header with bearerApiKey; the server distinguishes them by the ela\_ prefix on API keys.
