How to Redact Secrets from JSON Payloads

Mask tokens, passwords, cookies, emails, and phone numbers before storing or sharing JSON payloads.

Last updated: 2026-06-24

Redaction should happen before AI analysis, support tickets, screenshots, and shared links. Once a secret is copied into the wrong place, the damage is already done.

Fields to mask

authorization
cookie
set-cookie
token
secret
password
api_key
email addresses
phone numbers
JWT-like strings

Example

{
  "api_key": "sk_test_****1234",
  "customer_email": "j***@example.com"
}

Common mistakes

Only masking the body and forgetting headers
Looking for exact field names but missing nested values
Keeping a full raw payload in chat logs

FAQ

Should I remove the whole field or partially mask it?

Mask enough to preserve debugging context, such as the prefix and last 4 characters.

What about binary payloads?

Store metadata and size, not the rendered content, unless you have a safe review workflow.

Use WebhookPilot to review the sanitized payload before sharing it.
