Bird provides official SDKs for Node.js (npm), Python (PyPI), Go (go modules), Ruby (RubyGems), PHP (Packagist), and Java (Maven Central). All SDKs are open-source, maintained by Bird's engineering team, and include full type definitions.
Yes. Every Bird account includes a sandbox environment that mirrors production API behavior. You can send test messages, trigger webhook events, simulate delivery failures, and validate templates — all without sending real messages or incurring costs.
Failed webhook deliveries are retried with exponential backoff — at 1 minute, 5 minutes, 30 minutes, 2 hours, and 24 hours. Each payload includes an HMAC-SHA256 signature for verification. You can inspect failed deliveries and manually replay events from the dashboard or API.
Bird provides migration guides for Twilio, SendGrid, Vonage, and MessageBird. The API concepts map closely — most migrations involve updating API keys, adjusting payload formats, and reconfiguring webhooks. SDKs include adapter utilities for common migration patterns.
