Verdicts

Plivo API

US long code SMS $0.0077 a message and numbers $0.50 a month, with carrier surcharges listed per carrier. No OpenAPI spec.

WhatsApp Business Platform (Cloud API)

The first-party WhatsApp API has a public OpenAPI document, Markdown docs with llms.txt, numeric rate limits and a test number that sends without a payment method. Setup needs a person in three Meta dashboards, no idempotency key was found for sends, and Meta's terms restrict general-purpose AI assistants on the platform.

Before you call either

Plivo API

  1. Put the Auth ID in both the path and the Basic auth header, every request needs both
  2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After
  3. Give each agent its own subaccount to isolate credentials and spend
  4. Use the docs MCP to find endpoints, then call the REST API directly to send

WhatsApp Business Platform (Cloud API)

  1. Check when the user last wrote. Free-form messages are accepted only within 24 hours of the user's last message. After that, send an approved template.
  2. Record the message id from each send and match it to messages webhook statuses. Many failures arrive only by webhook, and no idempotency key was found.
  3. On error 130429 or 131056 wait and retry. Meta's guidance for the per-recipient limit is 4^X seconds, with X rising by one per failure.
  4. Verify X-Hub-Signature-256 with the app secret on every webhook, and deduplicate, because failed deliveries are retried for up to 7 days.
  5. Request health_status on the phone number before a campaign to see whether the app, business, account, number and template can send.
