Marketers can log in, tweak the design of an invoice or receipt, and hit save without needing a developer to push new code. Generous Free Tier:

This allows businesses to build multi-channel notification systems—such as sending a dual email confirmation and text alert for high-security actions like two-factor authentication (2FA) or urgent delivery updates. 3.

A quick glance at the GitHub repos shows a commitment to type safety. The PHP SDK, for example, uses DTOs (Data Transfer Objects) that auto-complete in IDEs, reducing the "guess the parameter name" fatigue that plagues less rigorous APIs.
