Yes. SendAPI provides WhatsApp, SMS, OTP, and transactional email through a single REST API — the same channels as MessageBird (now Bird) but with a unified key and simpler integration.
SendAPI uses flat monthly pricing with bundled usage across all channels. MessageBird charges per message with separate rate cards per channel. For predictable workloads, SendAPI is generally more cost-effective.
