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.

Vonage Messages API + MCP

POST /v1/messages covers six channels, with SMS failover for WhatsApp and RCS. No idempotency key, and channel rejections arrive only by status webhook after a 202.

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

Vonage Messages API + MCP

  1. Keep api.nexmo.com as the host, don't rewrite it to vonage.com
  2. Use the Messages API, not the legacy SMS API
  3. Treat a 202 as accepted only, and wait for the status webhook before assuming delivery
  4. Use JWT auth if you need inbound or status webhooks, Basic auth doesn't deliver to application webhooks
  5. Verify the webhook JWT and its payload_hash against the raw body
