Versioning

The version is in the path: every request goes to /v1. There is nothing to configure — no version header, no per-account setting.

Stability

v1 is additive. New endpoints, optional request fields, response fields, status and error-code values, and webhook event types arrive over time. Nothing that already exists is renamed, removed, or given a new meaning, so code written against v1 today keeps working as it grows.

Every change is recorded in the changelog.

SDK versions

Pin a tag rather than a branch, as the quickstart install commands do.
