## Verdicts

**360dialog WhatsApp API + MCP.** Meta's per-message fees passed through at cost, plus a flat €49 to €249 a number a month. No changelog, official SDK or standalone OpenAPI download.

**Photon.** Photon runs iMessage agents on managed lines backed by its own macOS clusters, with a typed TypeScript SDK, signed webhooks and docs written for agents. Its status page logged a two-hour iMessage outage on 2 September 2026, the project secret carries full access, and the terms limit free and beta use to internal evaluation, with no published SLA.

## Before you call either

### 360dialog WhatsApp API + MCP

1. Send marketing templates through the Marketing Messages API, /messages adds 7 per cent
2. Ask a docs page a question with `?ask=` before reading the whole page
3. Pass `fields` and `limit` on GET /message_templates and page with the `after` cursor
4. Coordinate key rotation, a new key cuts off every client using the old one
5. Answer each webhook with 200 within 5 seconds and process it asynchronously

### Photon

1. Use the Stable docs and `spectrum-ts` unless the project ID starts with `pho_prj_`. Stable and Beta packages, hosts and credentials don't mix
2. Design flows so the person texts first. Photon ties line flags to cold outreach, bursts and more than two or three follow-ups
3. Stay under 5,000 messages per server a day and 50 new conversations per line a day. Further sends are rejected until the window resets
4. Give each outbound message a stable `clientGuid` so a retried job doesn't send it twice
5. Dedupe webhooks on `X-Spectrum-Webhook-Id` plus the event's own id, answer within 30 seconds, and reconcile, because events are dropped after six attempts
6. Keep the project secret out of the agent's context. It grants full management access and doesn't expire
