chargebee/CHANGELOG.md

A library for integrating with Chargebee.

### v3.28.0 (2026-06-30)
* * *

### New Features
* Added an optional `telemetryAdapter` config hook for tracing Chargebee API calls via OpenTelemetry (or any APM). When unconfigured, the SDK skips all telemetry work — no behavior change for existing integrations.
* Each API call emits one CLIENT span (`chargebee.{resource}.{operation}`) with OpenTelemetry HTTP semantic-convention attributes plus `chargebee.*` attributes, and injects W3C trace context (`traceparent`) into outbound requests for distributed tracing.
* Exposed `TelemetryAdapter`, `RequestTelemetryContext`, `RequestTelemetryResult`, `RequestTelemetryError`, `RequestTelemetryHandle` types and the `TelemetryAttributeKeys` constant from the CJS and ESM entry points.
* Added a ready-to-use OpenTelemetry adapter via the `chargebee/telemetry/otel` subpath. `@opentelemetry/api` is an optional peer dependency and is not bundled — install it in your app to use this adapter.

### Enhancements:
- **Zod-backed request validation** — Set `enableValidation: true` in the client configuration to validate outgoing request parameters against each endpoint's generated Zod schema before the API call is sent. Invalid payloads raise `ChargebeeZodValidationError`, which carries the offending `actionName` and the original `ZodError` (including `issues` and `flatten()`) for inspection.
- **Runtime dependency** — Added [`zod`](https://www.npmjs.com/package/zod) (v4) as a runtime dependency to support request validation.

### v3.24.1 (2026-06-03)
* * *
### Bug Fixes:
- Fixed `Content-Length` header being computed from the JavaScript string length (UTF-16 code units) instead of the UTF-8 byte length. Requests with non-ASCII payloads (e.g. accented characters, CJK, emoji) under-declared `Content-Length` and were rejected by Node's `fetch`/undici (≥ 7.26.0) with `Request body length does not match content-length header`. The header is now computed via `Buffer.byteLength(data, 'utf8')`. Resolves https://github.com/chargebee/chargebee-node/issues/119. 

### Tests:
- ASCII form-urlencoded body — `Content-Length` matches the UTF-8 byte length of the serialized body.
- Multi-byte JSON body — `Content-Length` matches the UTF-8 byte length and is greater than the JS character count, ensuring the regression cannot return.


### v3.24.0 (2026-05-04)
