Guides

Guides explain how Bird works and how to build on it: the platform concepts that apply across every channel, plus a deep dive into each channel you send on.

Start with the platform guides if you're wiring up Bird itself: Authentication, how Users, teams & roles and Workspaces fit together, and Billing & usage. The API mechanics every integration leans on live here too: Webhooks & events, Idempotency, Errors, and Rate limits. Two cross-channel guides complete the platform layer: Deliverability covers the sender-reputation model, and Abuse & compliance covers how Bird keeps shared sending infrastructure healthy.

Then go channel-deep. The Email guide covers sending, domains and authentication, dedicated IPs, tracking, suppressions, and deliverability. The SMS guide covers free-form and template sends, the message log, and delivery events. The WhatsApp guide covers template messaging, phone-number setup, and metrics. The Verify guide covers one-time passcodes over email, SMS, and WhatsApp: send-and-check, country configuration, and sender branding.
