What a Shipping API Can Do
Unival's integration page describes four main jobs:
- Order integration. Connect online orders with your shipping workflow and reduce repetitive manual processing.
- Shipping labels. Streamline label creation and prepare shipments more efficiently.
- Shipment tracking. Keep tracking information connected so progress is easier to follow and manage.
- Multiple orders. Create and manage shipments while keeping tracking information connected.
The same page notes that the API is designed for websites, eCommerce platforms, shipping software and other business systems. Read the full description on our API and Shopify integration page.
Direct Carrier API or Provider Integration?
You can also integrate with a carrier directly. This table summarizes what FedEx's developer portal says, checked in October 2026.
| Stage | What FedEx says | What it means for you |
|---|---|---|
| Setup | Create an organization, link FedEx shipping accounts and create an API project | Plan time for account and project setup |
| Access | OAuth 2.0 tokens last about an hour and must be renewed | Your code must refresh tokens |
| Testing | A sandbox is available, and some APIs need certification before production | Check which APIs you plan to use |
| Labels | Ship and Open Ship need label certification, and FedEx's bar code review takes up to three business days | Allow time before go-live |
A direct integration uses your own carrier account and your own developers. A provider integration such as ours connects your system to the provider's shipping functionality instead. Which fits better depends on your team, your timeline and your rates.
Questions to Ask Before You Integrate
Use the same questions with every provider, including us:
- Which platforms and systems does the integration support?
- What access do you provide for development and testing?
- Who handles any carrier label certification, and how long does it take?
- Can I send the service level and shipment value with each order?
- How does tracking information reach my system?
- What rates apply to shipments created through the integration?
