I run an e-commerce site and I’m ready to simplify fulfilment by adding built-in UPS label generation. I already have an active UPS account; what I’m missing is the code that will let my team click “Create Label” from the order screen and immediately receive a printable PDF populated with the correct sender, recipient, weight and service data. My priorities are: • Seamless API authentication with my existing UPS credentials • Automatic label creation triggered from our order-management page (no manual re-entry of address or package details) • Returning the label as a ready-to-print PDF and saving the tracking number back to the order record The site is built on standard LAMP stack, so PHP solutions (or a lightweight microservice in Node/Python if better suited) are all fine, as long as they work reliably with our current checkout flow. The integration must stay within UPS’s official API limits and security guidelines. If you have previous experience wiring UPS label endpoints into a live storefront, please outline the approach you’d take, estimated turnaround, and any post-launch support you include. Quick, clean deployment and clear documentation are important to me so the in-house team can maintain it after hand-off.
