Common questions
Q.Does this verify signatures?
The first version focuses on formatting and inspection; signature verification depends on provider secrets.
Before using Webhook
When it helps
Webhook is useful when development, documentation, and automation workflows need repeated conversion, validation, and debugging steps in one place. It is designed for situations like turning {"event":"payment.success"} into Formatted event field without leaving the browser workflow.
Suggested workflow
The basic workflow is simple: enter Payload, adjust options when needed, and review Formatted payload. Before relying on the result, check the units, date, file type, rounding basis, or other assumptions that may change the outcome.
How to verify results
Webhook is a supporting utility for quick judgment. If the result affects contracts, filings, payments, security, customer data, or other important decisions, verify it against official sources, source systems, internal policy, or qualified review.
Data handling notice
Browser-local processing: the main calculation or conversion runs in your browser.
No server storage: except for UI preferences such as favorites, ZHS does not store your input files or text on the server.
Sensitive-data caution: even with local processing, avoid entering production secrets, national IDs, financial data, or raw customer data into public web tools.
