Connections
A Connection links one Sqquid Account to an external system. Sqquid exchanges information with ecommerce platforms, marketplaces, POS systems, and shipping services through these Connections.

Select a Connection name to manage it, or use a Connect card to add a system. The Healthy label indicates that a Connection is enabled; check Syncs to confirm its updates succeeded.
For a tour of adding and managing Connections in the app, see Daily Operations > Connections.
Before you configure a Connection, read about sources of truth, Locations and location mappings, and synchronization. The Connection guides describe the behavior of each external system.
How Connections fit together
Section titled “How Connections fit together”Connections have different roles:
| Role | What it does | Examples |
|---|---|---|
| Product and inventory source | Supplies the product information and available inventory that Sqquid uses as its starting point. | RunIt POS, Lightspeed Retail (X-Series), or Shopify Channels Hub |
| Sales Connection | Receives supported listing or inventory updates and sends orders to Sqquid. | Shopify, Amazon, eBay, Walmart, TikTok Shop |
| Service Connection | Provides a service, such as shipping. It does not receive customer orders. | EasyPost |
Your Account configuration determines which system is the source of truth. In a POS-led operation, the POS usually supplies product and inventory information. With Shopify Channels Hub, Shopify supplies it.

Section titled “Documented Connections”These guides cover the following systems:
| Type | Systems |
