Acenda's ShipStation integration sends marketplace orders to ShipStation, where your team creates labels and ships, and passes tracking back to each marketplace. A separate, optional connection lets ShipStation send its own stock counts into Acenda. ShipEngine, ShipStation's developer API, was renamed ShipStation API in February 2025.

How does ShipStation connect to Acenda?
ShipStation is shipping software from Auctane.
ShipEngine, ShipStation's developer API, was renamed ShipStation API on February 28, 2025.
Acenda's ShipStation integration connects your ShipStation account with an API Key and Secret generated in ShipStation's API settings. That API Key and Secret connection is separate from ShipStation API (formerly ShipEngine). If you use ShipStation API, our team confirms the setup during onboarding.
You choose which sales channels and warehouses ShipStation fulfills for.
Inside ShipStation, Acenda is available as a store connection under Selling Channels, which ShipStation currently labels Beta.
What moves between ShipStation and Acenda?
As a fulfillment provider, Acenda sends marketplace orders to ShipStation. Your team creates labels and ships in ShipStation. Acenda does not create the labels. Tracking (carrier, number, and ship date) comes back and is passed to each marketplace.
A separate, optional connection lets ShipStation send stock counts into Acenda. ShipStation pushes stock for the products you choose into a dedicated Acenda warehouse and overwrites that warehouse on each sync. The first sync can take up to an hour. After that, updates in practice come every 15 to 30 minutes for an active store, and ShipStation controls the timing. Some connections use a different schedule. You then map that warehouse to your sales channels.
Acenda sends inventory to each channel on that channel's own schedule, not the instant stock changes, and holds back any Inventory Floor you set.

Step-by-step setup is in Acenda's help center: "Acenda and ShipStation Integration: Step-by-Step Guide" and "How to Integrate Inventory from ShipStation with Acenda."
Connecting ShipStation lets you sell on the channels Acenda connects, including Walmart, Target Plus, Amazon. Listings, routing, and tracking for each channel stay in Acenda. See Explore all channels.
Connecting a system to Acenda doesn't affect whether a marketplace accepts your brand. Each retailer makes its own decision.
