Configuration

Published on: January 2, 2026

USPS OAuth Shipping is intentionally minimal in surface area. Every setting exists to solve a real operational problem; nothing more.

Global Settings

Found under WooCommerce → M Media USPS.

These settings apply across all shipping zones.

  • Client ID / Client Secret
    Your USPS OAuth credentials.
  • Origin ZIP Code
    The ZIP code packages ship from. This directly affects rate calculations.
  • Rate Adjustment (%)
    Apply a global markup or discount. Negative values reduce rates; positive values increase them.
  • Handling Fee
    A fixed dollar amount added to every rate.
  • Sandbox Mode
    Routes requests to the USPS test environment. Use this when validating setup or troubleshooting.
  • Default Package Dimensions
    Used when a product does not define its own dimensions.

Shipping Zone Settings

Configured per zone under WooCommerce → Settings → Shipping.

Each zone allows you to:

  • Enable or disable USPS OAuth Shipping
  • Customize the method title shown to customers
  • Select which domestic and international USPS services are offered
  • Define a fallback rate to display if the USPS API is unavailable

Fallback rates are optional but recommended for stores that prioritize checkout continuity.

Supported Services

Domestic

  • Media Mail
  • USPS Ground Advantage

International

Built by People Who Actually Use the Software

M Media software isn't venture-funded, trend-chasing, or built to look good in pitch decks. It's built by developers who run their own servers, ship their own products, and rely on these tools every day.

That means fewer abstractions, fewer dependencies, and fewer "coming soon" promises. Our software exists because we needed it to exist — to automate real work, solve real problems, and keep systems running without babysitting.

We build software the way it used to be built: practical, durable, and accountable. If a feature doesn't save time, reduce friction, or make something more reliable, it doesn't ship.

✓ Every feature solves a problem we actually had
✓ No investor timelines forcing half-baked releases
✓ Updates add value, not just version numbers
✓ Documentation written by people who got stuck first

This is software designed to stay installed — not be replaced next quarter.

No Bloat. No Spyware. No Nonsense.

Modern software has become surveillance dressed as convenience. Every click tracked, every behavior analyzed, every action monetized. M Media software doesn't play that game.

Our apps don't phone home, don't collect telemetry, and don't require accounts for features that should work offline. No analytics dashboards measuring your "engagement." No A/B tests optimizing how long you stay trapped in the interface.

We build tools, not attention traps.

The code does what it says on the tin — nothing more, nothing less. No hidden services running in the background. No dependencies on third-party APIs that might disappear tomorrow. No frameworks that require 500MB of node_modules to display a button.

✓ Your data stays on your device
✓ No "anonymous" usage statistics
✓ Minimal dependencies, fewer risks
✓ Respects CPU, RAM, and battery
