Verdicts

Expo Push Notifications

A free push relay with a small, well documented HTTP API, published limits of 600 notifications a second and written error codes. Sending needs no credential unless the owner turns on access tokens, there is no idempotency key or SLA, and the status page records three iOS push incidents since 4 August 2026.

MagicBell

A public OpenAPI 3.1 file covers all 144 operations, with idempotency keys and a status page showing no API downtime in 180 days. No batching or digest step, llms.txt, error code list, SLA or sub-processor list was found, and project tokens carry no scopes.

Before you call either

Expo Push Notifications

  1. Send an array of up to 100 messages per request, all for one project, and stay under 600 notifications a second
  2. Keep each ticket id and POST them to /--/api/v2/push/getReceipts about 15 minutes later. Receipts are cleared after 24 hours
  3. Stop sending to a token when a ticket or receipt returns DeviceNotRegistered
  4. If the project has enhanced push security on, send Authorization: Bearer <access token> or the call fails with UNAUTHORIZED
  5. Retry 429 and 5xx with exponential backoff, and expect an occasional duplicate because there is no idempotency key

MagicBell

  1. Ask the owner for a Project JWT from the dashboard's Project Auth page. The terms forbid accounts registered by automated methods
  2. Send Idempotency-Key with a UUID on POST /v2/broadcasts, and reuse it on a retry within 24 hours
  3. Stay under 500 requests a minute per IP. A 429 blocks the address for 60 seconds, so put many recipients in one broadcast
  4. Use a Project JWT for broadcasts, users, integrations and workflows, and a User JWT for one user's inbox, tokens and preferences
  5. Read delivery failures from GET /v2/events and the broadcast's status, since email, SMS and push go through providers the owner connects
