Verdicts

Infobip API + MCP

API keys with scopes, expiry dates and IP allowlists, and OAuth 2.1 on the MCP servers. Europe-wide traffic processing degraded on 2026-08-10 (about 1 hour) and 2026-08-15 (about 3 hours).

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

Infobip API + MCP

  1. Use the account's own base URL (<subdomain>.api.infobip.com), not a generic host
  2. Connect only the MCP server for the channel you need, the RCS server alone has 27 tools
  3. Create a key with only the scopes the agent needs and an expiry date
  4. Send trial messages from ServiceSMS to verified numbers only (up to 5)

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.
