Messaging

Register a browser Web Push subscription

Register a browser `PushSubscription` (the `endpoint` plus the `p256dh` / `auth` keys returned by `pushManager.subscribe()`) so it becomes eligible to receive native Web Push. The send endpoint (`/messaging/push`) only delivers to subscriptions registered to the project, so a caller cannot push to arbitrary or other-tenant endpoints. Registration is idempotent - re-registering the same endpoint updates the existing row (keys rotate, `lastSeenAt` bumps) instead of creating a duplicate. Each project has a cap on the number of registered subscriptions; when the cap is reached, the least-recently-seen subscriptions are evicted to make room. Optionally associate the subscription with a `userId` (your end-user id, for targeted sends) and a `deviceId`. Accepts: OrgBearerAuth (for admin users), ProjectBearerAuth (JWT for authenticated users), or ApiKeyAuth (X-API-Key for programmatic access).

SDK setup

Create a client and set credentials (JWT and/or API key) before calling the API. Match the authentication type shown above.

import { Configuration, MessagingApi } from 'mudbase-sdk';

const configuration = new Configuration({
  basePath: 'https://cloud.mudbase.dev',
  apiKey: 'sk_live_mudbase_doc_Xk9mP2qR7vN4wL8jH3tY6uE',
  accessToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c3JfbW9yZ2FuX2RlIiwiZW1haWwiOiJtb3JnYW4uY2hlbkBub3J0aHdpbmQuZGV2IiwiZXhwIjoxODI1MTI5NjAwfQ.doc_preview_sig',
});
// This endpoint accepts either credential - apiKey or accessToken alone is enough.

const messaging = new MessagingApi(configuration);
import { Configuration, MessagingApi } from 'mudbase-sdk';

const configuration = new Configuration({
  basePath: 'https://cloud.mudbase.dev',
  apiKey: 'sk_live_mudbase_doc_Xk9mP2qR7vN4wL8jH3tY6uE',
  accessToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c3JfbW9yZ2FuX2RlIiwiZW1haWwiOiJtb3JnYW4uY2hlbkBub3J0aHdpbmQuZGV2IiwiZXhwIjoxODI1MTI5NjAwfQ.doc_preview_sig',
});
// This endpoint accepts either credential - apiKey or accessToken alone is enough.

const messaging = new MessagingApi(configuration);

Example request
