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.

Novu

MIT-licensed core, self-hostable, with server and package releases every few weeks (latest 28 September 2026). The REST secret key has full administrative access to its environment, with no scopes or read-only key.

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

Novu

  1. Send Authorization: ApiKey <key> to the REST API. Bearer is for the MCP server
  2. Ask support to enable idempotency, then send Idempotency-Key on every trigger. A 409 means the first call is still running
  3. Use eu.api.novu.co and eu.mcp.novu.co for an EU account. A US key won't authenticate there
  4. Pass environmentId from get_environments on MCP calls. OAuth sessions default to Development
  5. Keep limit at 100 or below on list calls. Higher values return 422
