The National Emergency Response Information System (NERIS) is advancing its mission to modernize emergency response data management through the release of a new application programming interface (API) infrastructure - the first in a series of API releases.

This API focuses on three core data schemas: Fire Department Specification, Computer-Aided Dispatch, and Incident Data. By facilitating automated data exchanges, NERIS aims to replace outdated, manual processes (zip files in email) with a streamlined system that enables near real-time data sharing and retrieval.

This development marks a significant step toward improving the connectivity and interoperability of emergency response services across the nation. It is a foundational element in modernizing how fire departments and emergency services collect, manage, and exchange data.

What are APIs?

APIs act as links between software systems, creating a bridge for seamless communication. In the context of NERIS, the API enables CAD/RMS clients to transmit and receive data in JSON format. This capability allows Computer-Aided Dispatch (CAD) and Records Management System (RMS) vendors to automatically send data payloads to NERIS and retrieve enhanced information, integrating it with other datasets. The API's structure ensures data integrity through strict validation rules, preventing the acceptance of invalid data structures and ensuring the reliability of the data collected.

NERIS utilizes RESTful architecture, which relies on standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources. This approach simplifies interactions by defining clear actions: GET retrieves data, POST creates new resources, PUT updates existing ones, and DELETE removes them.

Key features of the API release include:

• Documentation available through Swagger, allowing end users to visualize and interact with API resources.
• A sandbox environment for developers to test payload submissions and refine their integrations.
• Monthly "NERIS Office Hours" conducted by the NERIS development team to provide support and answer questions for CAD/RMS vendors.

Future Implications

By enabling data connectivity between systems, NERIS will enhance the efficiency and effectiveness of emergency services nationwide. As departments and vendors integrate this API into their operations, the potential for improved decision-making and resource allocation will become increasingly attainable.
