An integration tool for universal connection of Microsoft Dynamics to any REST API–based system
Easy integration with REST APIs of external systems
Configuration of integration scenarios without deep coding
Data synchronization and management between Dynamics and external services
Ability to extend integrations according to business needs

RESTwithUS is an extension for Microsoft Dynamics 365 Business Central and NAV that enables ERP integration with any external system or service supporting REST APIs. It allows you to define API requests, authentication, parameters, and responses directly within the system, without the need for complex custom development.
With RESTwithUS, you can:
easily read, create, update, and delete data in external systems
Synchronize records between ERP and other applications
work with data in real time or according to a defined schedule
manage REST API communication directly from the Dynamics environment
RESTwithUS covers the essential areas of working with REST APIs:
API provider configuration – support for multiple authentication methods (API keys, Basic, OAuth, etc.)
Entity and field mapping – mapping JSON responses to Dynamics tables and fields
API operation definitions – configuration of GET, POST, PUT, PATCH, and DELETE calls
Connection and data management – monitoring API calls, errors, and logs directly within the system
RESTwithUS is suitable for organizations that need to:
integrate ERP with external systems such as e-commerce platforms, CRM solutions, helpdesk systems, or custom applications
synchronize customers, orders, inventory, and other business data
automate data flows between Microsoft Dynamics and other applications
Reduce manual intervention and errors in system integrations
RESTwithUS eliminates the need for standalone integration development and provides a straightforward interface for managing integrations directly within the ERP environment.
RESTwithUS can be deployed as a standard extension for Business Central or NAV. It is designed to be gradually expanded based on current integration needs—adding new API services, operation types, entity mappings, and scenarios without modifying the ERP core.
Integration management and monitoring are handled directly within Dynamics, allowing IT teams to maintain visibility and respond quickly to changes or issues.
