SDK Overview

Checked-in SDKs and wrappers for Zentra’s reviewed BaaS surface

SDK Overview

Zentra provides checked-in SDKs and wrappers for the most common server-side and app environments. They wrap the REST API, normalize authentication, and expose helpers for the main BaaS products.

Some generated SDKs still include compatibility helpers such as customers, wallets, savings, or subscriptions. Identity is part of the reviewed gateway surface, but it remains tenant-gated. Treat transfers, webhooks, virtual accounts, payments, cards, and tenant-enabled identity as the reviewed public HTTP surfaces; treat the rest as compatibility or draft unless your tenant explicitly enables them.

Use SDK Surface Status when you need the current reviewed-vs-draft breakdown across the checked-in SDKs and wrappers.
