Celerant API
Celerant Technology is a unified omnichannel retail platform delivering point of sale, eCommerce, inventory, CRM, and back-office software through its Cumulus Retail and Stratus Enterprise products. An unofficial API lets you programmatically pull orders, inventory, products, and customer records—and push updates like new orders, inventory adjustments, and customer loyalty activity—across in-store and online channels.
What is Celerant?
Celerant Technology is a retail software vendor offering unified omnichannel management for thousands of retailers across apparel, footwear, sporting goods, firearms (FFL), pet supply, pharmacy, hardware, wine and liquor, and other specialty verticals. Retailers use Celerant to run point of sale, eCommerce, inventory, customer relationship management, loyalty, digital marketing, and back-office reporting from a single platform, synchronizing pricing, inventory, and customer data across in-store and online channels.
Core product families:
- Cumulus Retail (cloud POS, eCommerce, inventory, loyalty, and mobile apps for small-to-mid-size retailers)
- Stratus Enterprise (advanced customization, ERP, fulfillment, and analytics for complex multi-location retailers)
- Point of Sale and integrated eCommerce storefronts
- Inventory Management and back-office reporting
- CRM, loyalty rewards, and digital marketing tools
Common data entities:
- Products, SKUs, Pricing, Inventory levels
- Orders, Sales transactions, Returns, Tenders
- Customers, Loyalty accounts, Rewards
- Purchase orders, Vendors, Receiving
- Locations, Registers, Employees
The Celerant Integration Challenge
Retailers run mission-critical sales and inventory workloads on Celerant daily, but turning its portal- and integration-driven workflows into clean API-driven automation is non-trivial:
- Integration over open API: Celerant emphasizes pre-built and custom-managed integrations rather than a broadly published, self-serve public API, so connecting a new system often routes through a partnership or custom development engagement
- Two product platforms: Cumulus Retail and Stratus Enterprise have different deployment models, customization depth, and object behavior—generic integrations break across them
- Omnichannel data spread: POS, eCommerce, and back office each touch inventory, pricing, and customer records, and keeping them reconciled across channels is error-prone
- Per-retailer configuration: Specialty verticals (FFL firearms, pharmacy, CBD/vape) add compliance fields and workflows that vary by merchant
- Authentication and session handling: Back-office and portal access require credentialed sessions that complicate headless, automated access
- Batch and sync timing: Inventory, pricing, and order synchronization between POS and eCommerce runs on platform-defined cadences that downstream systems must account for

Frequently asked questions
Yes. Supergood adapts to either platform, normalizing product, order, inventory, and customer entities so you integrate once regardless of whether you run Cumulus Retail or Stratus Enterprise.
Celerant emphasizes pre-built and custom-managed integrations rather than a broadly published, self-serve public API. Supergood works against your authenticated account surfaces, so you get a clean API without a custom integration engagement.
Yes. Supergood normalizes inventory and pricing across POS and eCommerce channels, so you can read stock levels and push adjustments that keep in-store and online consistent.
Each account is profiled against its configured fields and workflows, so vertical-specific attributes—such as FFL firearms or pharmacy compliance data—are preserved rather than dropped into a generic schema.
Orders, returns, tenders, customer profiles, and loyalty/rewards activity are exposed through the same normalized API surface, so transactional and CRM data sit alongside catalog and inventory entities.
