Why tools?
Docs are better when they're not just text. These widgets reduce friction and help teams ship faster.
Each tool is designed to answer a specific operational question:
- API playground: generate realistic requests, learn required headers, and copy a cURL.
- Webhook simulator: generate event payloads and signatures to test your receiver.
- Warmup calculator: plan a ramp that reduces throttling and spam placement risk.
- Bounce code lookup: interpret SMTP and enhanced status codes and decide what to do.
- Email preview: render HTML like a recipient and spot obvious template issues early.
If you are building your first integration, start with:
- Authentication: API authentication
- Safe retries: Idempotency
- Production debugging: Observability
