What Makes a High-Quality Shift4Shop 3PL Integration?

1. Easy-to-Use Software

2. Speed and Accuracy Guarantees

3. People who Get Ecommerce

Setting up a Shift4Shop Integration is simple.

Here’s how Red Stag’s integration works:


Connect your Shift4Shop store

A simple API key connects your store to Red Stag’s platform. Our team can complete this for you if you’d like.


Set the rules that work for you

Push orders every 15 minutes, delay them for QA by your team, set SKU-specific rules, and more.


Push data back to your store

Shipping notices, tracking numbers, and more can be sent back to you. Display in-cart shipping rates based on actual data.


Continue receiving all the data you need

If we know it, you’ll know it. Reports and real-time data are available on just about anything you can imagine — inventory levels, shipping statuses, and more.


Update and tweak as your needs change

Red Stag’s Shift4Shop integration is designed to be modular and accessible, so you can make changes in minutes, without a developer (but if you need us – we’re there).

Know that your orders are 100% accurate.

If we mess it up, we pay for it.

Reach 96% of the U.S. in 2-days with ground shipping.

Red Stag Fulfillment was built for ecommerce operators, by ecommerce operators. Our founders experienced the pain of a bad 3PL relationship firsthand. So, they founded Red Stag to operate differently.
