Lightspeed eCom (C-Series) has an open API. This tool lets third-party developers build software applications, integrations, and extensions to exapand eCom (C-Series) with additional functionalities, specially-tailored to your business needs.

Once you've integrated eCom (C-Series) and Retail POS, Retail POS should be treated as the system of record. To keep your data accurate, only make changes to synced information exclusively in Retail POS. Updates to product made in eCom (C-Series) may be overwritten, or cause syncing issues. If your integration needs to manage products, you may want a connection to the Retail POS API instead.

eCom also offers an extensive App Store with existing third-party applications. There are some apps in the App Store that are not compatible with the omnichannel integration because they modify products or stock levels directly in eCom. A warning message will display if you try to integrate an incompatible app.
