Roles & Permissions for Embedded Analytics
Edited 50 days ago
Access to Fluent Embedded Analytics is controlled through a combination of permissions and role-based access control (RBAC). This document defines the permission model, role requirements, and configuration patterns for access to Fluent Analytics.Access to Fluent Analytics is controlled through a two-layer model: users must be assigned a role that 
  • has the `ANALYTICS_VIEW` permission AND 
  • is listed in the Analytics Query definition.
Embedded Analytics Query Settings
Edited 51 days ago
Embedded Analytics Queries are configured through settings that map query names to analytics resources in the Fluent Analytics backend services. Each setting follows the pattern `fc.analytics.queries.{domain}` and defines available queries, their resource locations, access permissions, and optional default parameters. Use this document to:
  • Understand query setting structure and naming conventions
  • Configure new analytics queries
  • Set default parameters for queries
  • Control query access through role-based permissions
Query Structure for Embedded Analytics
Edited 50 days ago
This document defines the structure and syntax for querying the Fluent Embedded Analytics backend services. Analytics Queries reference pre-configured metrics by name (called "targets"), rather than defining individual fields like standard GraphQL queries. Targets provide controlled access to analytics metrics with built-in role-based permissions. Use this document to: 
  • Understand and construct analytics GraphQL queries 
  • Understand target name format and how it links to query settings
  • Configure filter parameters to refine query results 
  • Integrate analytics into dashboards and web applications

Control Types
Edited 44 days ago
This page describes how to configure a control: the structure of the control data and the values each standard control type expects. For what each type does and how the utility resolves and applies controls, see the Controls Utilities Overview and the Detailed Technical Description on the Controls Utilities page.
Controls Utilities Overview
Edited 42 days ago
The Controls Utilities library (`util-controls`) applies controls to a catalog position in a consistent, reusable way. Rather than each rule reimplementing how to find and apply controls, a rule calls `ControlUtils.applyControls(...)`, which loads the required data from GraphQL, evaluates the applicable controls, and returns an updated position together with an audit of every change.

Control Utils
Edited 44 days ago
`ControlUtils` is the entry point of the Controls Utilities bundle. This page is the API reference for applying controls to a position from a rule.For the underlying concepts (control, control group, bulk vs position-level control) see Controls Utilities Overview. For the order in which the `ControlUtils` resolves and applies controls, and the behavior of the caches, see the Detailed Technical Description on the Controls Utilities package page.

A user sees the number that matters without leaving the screen they are already working on.It is built for monitoring in context: four reference dashboards covering Orders, Fulfillments, Inventory, and Returns, plus the ability to place any single metric on any page. Metrics come from the Fluent Metrics Library.

How Controls Utilities work
Edited 44 days ago

IPC vs. IPU – Understanding Inventory Measuring Models in Fluent Commerce
Edited 492 days ago
Fluent Commerce supports two different models for measuring inventory updates: Inventory Position Updates (IPU) and Inventory Position Changes (IPC). These models play a key role in how we track and charge for inventory processing activity on the platform.With the introduction of Inventory Batch Pre-Processing (BPP) and advancements in ingestion optimization, IPC has emerged as the modern, cost-efficient model. This article outlines the differences between IPU and IPC, how they relate to inventory processing, and when each is applicable.
