ArcGIS Velocity supports extensible real-time data ingestion through gRPC (generic Remote Procedure Call) and HTTP. Learn how to get started building standalone apps to push real-time data into ArcGIS feeds from external systems and custom client applications. Topics will include exploring gRPC developer resources, required client libraries, data packaging examples, and connecting to a gRPC feed to update features in a web map. In addition, you will learn how ArcGIS Velocity supports real-time data ingestion and egress or actuation through HTTP, which enables you to integrate with third-party APIs. Topics will include how to configure HTTP Receiver inputs, HTTP outputs, URL parameters, authentication, and custom headers to interact with external APIs and systems through HTTP.
