August 2026

Updated through August 8, 2026.

​
Tenant-safe customer provisioning

  • Routed Node.js and Python customers.upsert() calls directly to Nozle Core using the merchant’s secret key.
  • Removed master-organization authentication from the Engine customer compatibility endpoint.
  • Added local SDK validation and tenant-isolation regressions for customer provisioning.
  • Verified Node.js and Python customer creation against the Pullse Testing production organization with disposable canaries.

​
Mixed Entity checkout and billing anchors

  • Added one-invoice, one-payment checkout for mixed Entity plan baskets of up to 100 Entities.
  • Added a stable customer-level Entity billing anchor established only after the first successful paid checkout.
  • Added anniversary-aligned proration for Entity plans purchased after the anchor is established.
  • Added replay-safe checkout batches and fail-closed protection for concurrent first-paid checkouts.
  • Clarified that paid top-ups enter the customer pool and are allocated explicitly to Entities.

​
Entity-owned subscriptions and SDK 0.5.0

  • Added independent subscriptions for customer Entities, including mixed monthly and annual plans under one paying customer.
  • Added Entity-scoped checkout, plan changes, end-of-period cancellation, stable subscription identities, and payment-gated activation.
  • Added suspended, deleted, and recreated Entity protection so stale identities cannot inherit billing state.
  • Released the backend integration surface in @nozle-js/node 0.5.0 and nozle-sdk 0.5.0.
  • Verified the Core API and published Python SDK against production with reversible Entity-subscription canaries.

​
Subscription settlement controls

  • Added preview and apply APIs for cancellation, downgrade, and uncancel transitions.
  • Added merchant-controlled timing, billing-anchor, proration, credit, refund, offset, and final-invoice policies.
  • Added idempotent transition application so uncertain requests can be retried safely.
  • Released the settlement controls in @nozle-js/node 0.4.2 and nozle-sdk 0.4.2.

​
Developer experience

  • Completed the React, Node.js, and Python SDK references with current signatures and security guidance.
  • Added rendered React component previews and a dedicated theming reference.
  • Replaced customer-specific examples with neutral, reusable integration examples.
  • Restored the complete Nozle Billing API reference with generated request, response, and schema documentation.

​
July 2026

​
Product credits

  • Introduced exact-decimal credit systems, plan grants, paid top-ups, immutable balance sources, and operation history.
  • Added advisory usage checks and atomic, idempotent credit consumption.
  • Added durable usage-event publication and reconciliation so committed deductions survive downstream outages.
  • Added customer and Entity balance APIs, per-Entity grants, shared-pool policies, and top-up allocation/deallocation.

​
Payment-first billing

  • Paid plan changes now preserve the current plan until payment succeeds.
  • Added payment-aware checkout results for hosted Stripe, embedded Stripe, immediate completion, and scheduled changes.
  • Added durable upgrade webhook processing and support for end-of-period cancellation.
  • Added merchant-configurable billing anchors and transition-policy defaults.

​
Security and tenancy

  • Restricted publishable keys to the public plan catalog.
  • Moved customer billing operations behind authenticated merchant backends and least-privilege secret keys.
  • Hardened customer, organization, mutation, and internal service authorization.
  • Removed automatic seat billing from Entity lifecycle changes; merchants now emit explicit, idempotent seat events.

​
SDKs and dashboard

  • Added product-credit and Entity APIs to the Node.js and Python SDKs.
  • Refactored React checkout around merchant-owned callbacks and forwarded validated return URLs to Stripe.
  • Added customer and Entity credit dashboards, paid top-up checkout, and refreshed analytics and settings interfaces.

​
June 2026

​
Entitlement rework

  • Added two-path entitlement resolution for feature gates and usage limits.
  • Added margin-aware decision fields: cost_per_use_cents, revenue_per_use_cents, and margin_per_use_cents.

​
Checkout flow

  • Introduced invoice-first embedded Stripe checkout.
  • Made plan activation payment-gated.
  • Added one-off invoice checkout for credit top-ups and add-ons.

​
SDK updates

  • Released initial LLM usage capture for OpenAI and Anthropic in the Node.js and Python SDKs.
