Bird: API Design & Integration Surface

Docs-backed

REST API at api.bird.com (or channel-specific endpoints for SMS, WhatsApp, etc.). Channels API provides a unified interface: POST /workspaces/{id}/channels/{channelId}/messages. SMS API: POST to originator number, text body, recipient. WhatsApp API: templated messages require pre-approved templates. Conversations API for thread management. Response includes message ID and status for delivery tracking. Webhooks for inbound messages and delivery status events.

Bird: Error Handling & Operational Reliability

Docs-backed

Structured error responses: HTTP status codes with JSON body containing errors array (each with code and description). 401 for invalid AccessKey, 422 for invalid phone number format, 429 for rate limit exceeded with Retry-After header. Delivery status webhooks surface provider-level errors (NACK, failed, delivery_failed). Bird's infrastructure handles carrier routing with fallback logic. SLA terms available for enterprise customers.

Bird: Comprehensive Agent-Usability Assessment

Docs-backed

Bird (rebranded from MessageBird in 2023) is a cloud communications platform (CPaaS) offering SMS, WhatsApp Business, voice calls, email, and chat messaging through a unified REST API. For agents, the key capabilities are: sending SMS/WhatsApp messages programmatically, handling inbound messages via webhooks, managing conversations across channels, and OTP/2FA delivery. The Channels API provides a consistent interface across communication channels — one API call can route to SMS, WhatsApp, or email based on channel configuration. Strong enterprise client base (Heineken, Uber, Google). Confidence is docs-derived.

Bird: Auth & Access Control

Docs-backed

Bearer token auth via AccessKey header. Workspace-scoped API keys with configurable permissions. Separate signing keys for webhook signature verification (HMAC-SHA256). No OAuth2 for direct API access; API key pattern. Key management via Bird dashboard. WhatsApp Business access requires Meta approval — a platform-level constraint outside Bird's control. SMS sending in some regions requires number verification.

Bird: Documentation & Developer Experience

Docs-backed

Getting started guides, API reference, webhook setup, and SDK documentation (Node.js, Python, Java, PHP, Ruby). WhatsApp template management and approval process well-documented. Documentation quality is high; the rebrand from MessageBird is reflected in updated docs. Community support via Discord and email.
