About sendapi
SendAPI is a unified messaging API for developers. A single REST endpoint and API key handle WhatsApp, SMS, OTP verification codes and transactional email sending. SMS reaches 190+ countries, WhatsApp connects from your own number with a QR scan and supports rich media and two-way conversations without a Meta application, and OTP flows can fail over from SMS to WhatsApp to email.
Email features include dedicated IP pools, DKIM, SPF and DMARC and real-time delivery webhooks. Developers also get typed SDKs in TypeScript, Python and Go, safe retries through idempotency keys, and self-serve signup. The site calls itself an official Meta Business Partner.
Plans are Starter at $9.99 (5,000 emails, 1 WhatsApp session, 1 API key), Growth at $29.99 (25,000 emails, 3), Business at $79.99 (100,000 emails, 10) and a custom Enterprise plan. SMS is billed through top-up credits, and all plans have a 7-day free trial.
