Verdicts

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.

OneSignal

Runs push delivery itself, so there's no separate push provider to wire up. Three incidents on the API and SDK endpoints in September 2026.

Before you call either

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

OneSignal

  1. Use Authorization: Key <key>, not Bearer, and put app_id in the body
  2. Send an idempotency_key UUID with every create call and reuse it on each retry
  3. On 429, wait for Retry-After, then back off with jitter, up to 10 attempts
  4. Stay under 10 sends per subscribed subscription in 15 minutes or the app is disabled
  5. Target people with include_aliases.external_id and set target_channel
