The New Relic Insights Dashboard API is a REST API designed to provide programmatic control over dashboards in sub-accounts and across an organization, enabling unique solutions and automation of dashboard management. The API offers five endpoints for creating, listing, showing, updating, and deleting dashboards, as well as additional functionality like filtering and pagination. To use the API, customers must generate a user-level admin API key and navigate to the different endpoint using the New Relic API Explorer. The Insights Dashboard API can be valuable in various use cases, such as reinforcing monitoring culture, creating shared knowledge, eliminating "what should I monitor" questions, leveraging automation to increase efficiency, and supporting a consistent monitoring process across teams and departments.
