BillingWebhookKit is a browser-only testing tool. The hosted app has no backend and does not upload webhook signing secrets, pasted payloads, or generated fixtures.

Use GitHub issues for security-relevant bugs that do not contain private secrets or customer data:

https://github.com/qihaze123/billing-webhook-kit/issues

Do not post:

• Real webhook signing secrets
• Production API keys
• Customer emails or order identifiers
• Private checkout URLs
• Raw production webhook payloads

If a report needs sensitive context, first open a minimal issue describing the class of problem without secrets.

• Static GitHub Pages app
• Browser-only Web Crypto signature utilities
• Public free sample package
• Public documentation and guide pages

The paid Pro Kit is a local digital asset pack. Do not include private Pro Kit archive contents in public issues unless the same file is already present in the public free sample or manifest.
