Working code for the API integrations PHP developers actually ship: SDK setup, webhook signatures, subscription lifecycle, error taxonomies, fee math. Targeting the current Stripe SDK – no copy-paste from someone else's 2018 tutorial.
Not a rehash of the SDK readme. Every snippet is written and tested against the current Stripe PHP library, with the gotchas the official docs gloss over.
Raw bodies, signature checks, idempotency, fee math, the Laravel and Symfony traps. The plumbing that breaks in production, covered in full.
Each guide is original in English, Russian, German and Spanish – not machine-translated, written for developers in their own language.
