ECRS released updated Third-Party Integration and API Guidance this week, a formal framework defining how retailers and solution providers can connect with its CATAPULT point-of-sale platform through standardized, reusable API endpoints. The documentation is designed to reduce technical friction for integrators while protecting the platform’s stability across high-volume retail environments.
Why standardization matters
The guidance codifies an integration philosophy ECRS has been building toward for five years. Pete Catoe, founder and CEO of ECRS, said the shift to generic, open endpoints is fundamental to how the company thinks about third-party relationships.
“Over the last five years, ECRS has executed our vision of delivering generic, open API endpoints that enable our customers and third-party providers to fully leverage the CATAPULT transactional ecosystem. This commitment continues to accelerate as we remain focused on serving our retailers first, giving them the flexibility and adaptability that only a truly open system can provide,” Catoe said.
The core principle: ECRS will not build or maintain custom or exclusive APIs for individual third-party providers. All integrations must be built against standard interfaces that any qualified developer can access — a governance choice designed to prevent technical debt and ensure integrations remain functional as CATAPULT evolves.
How the integration process works
The guidance establishes a five-step workflow for new integrations. Integrators first identify the business use case, then ECRS evaluates which existing standard APIs already address the need. If new API development is required, an active CATAPULT retailer must sponsor and fund the effort. Third parties then build against the resulting generic endpoint — not a custom solution — and validate performance in a live retail environment before production release.
The customer sponsorship requirement is a deliberate design choice. It ensures that new API development is driven by real operational needs at the store level rather than vendor priorities, and that the resulting interface serves the broader retailer community rather than a single integration partner.
Scope of available APIs
The guidance consolidates documentation for ECRS’ suite of REST API and API client solutions, covering operational workflows, analytics, loyalty, e-commerce and enterprise management functions. Full documentation is available at ecrs.com/catapult-api.
