GitHub's October 7 article on secret protection discusses protecting credentials as software production grows. A tiny publishing script has the same boundary: the post belongs in public; the token does not.
Load credentials from a local environment file or a secret store. Keep the file out of version control. Print whether a token is configured rather than printing its value.
Be careful with failure handling. Some API clients include request headers or a full URL in an exception. If authentication appears in the URL, logging the exception can disclose it. Keep a safe error summary and redact credentials before saving diagnostics.
Use the narrowest permissions the platform offers. A publishing job should not need access to unrelated accounts. Keep the credential separate from your article manifest, so you can share the content without sharing account access.
After an accidental disclosure, revoke or rotate the credential. Removing the visible line does not invalidate copies in history, logs or caches.
One practical check before your first live run: trigger a harmless request failure, then inspect the resulting log. Is it useful enough to debug, and safe enough to send to someone else?
The token shown on the cover is fictional.
