Defines the programming interface that both the client and service agree upon to communicate through using interprocess communication (IPC). | | Client | See Host Application. | | Client ID | DT provides this unique identifier for the client or Host App in each DT environment. DT derives this unique identifier from the APK that you send to DT; it is unique to each environment. | | Client Secret | Unique secret passphrase assigned to the client or Host App. Used during SDK initialization and must be stored securely. | | DPP | Dynamic Preload Platform. Loads selected apps for specific mobile devices and operators. | | DT Ignite | Dynamic Preload Platform (DPP) for Android OS that allows Mobile Network Operators (MNOs) to preinstall applications. | | Host Application | Application that interacts with DT Ignite through the Ignite Services API to present target applications for installation. Also referred to as Host App, Client, Integrator, or Integrator App. | | Ignite Services API | Component of DT Ignite that allows authenticated host applications to interact with applications and application metadata securely. Also referred to as Ignite API. | | Ignite Services Client SDK | Software library that provides a set of features to consume the Ignite Services API AIDL in a convenient, simplified way. | | Integrator | See Host Application. | | IPC | Interprocess communication. | | Operator | Provider of wireless communications services that owns or controls all components required to sell and deliver services to end users, including radio spectrum allocation, wireless network infrastructure, billing, customer care, provisioning, marketing, and repair organizations.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.digitalturbine.com/dt-ignite/getting-started-with-the-dt-ignite-services-sdk/key-dtis-terms.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
