ERP API Integration Explained: REST, Webhooks, Auth and Idempotency
A plain-English explanation of ERP API integration: REST APIs, webhooks, authentication methods, idempotency, pagination, rate limits and error handling.
Integration · Analytics
Overview
We build a reporting layer — views or a warehouse — with agreed definitions, then a Power BI model on top that refreshes reliably and respects access rights.
01Data
| Entity | Direction | Notes |
|---|---|---|
| Sales & orders | ERP → App | Fact tables by date, customer, product and channel. |
| Inventory | ERP → App | Stock snapshots and movements. |
| Finance | ERP → App | GL balances, budgets and analytic data. |
| Operations | ERP → App | Production, delivery and service KPIs. |
| Master data | ERP → App | Dimensions for products, customers, sites. |
02Use cases
Monthly financial and operational packs.
ERP combined with CRM, marketing or web data.
Sales, stock and service KPIs by team.
03 — Architecture
Data flows from the ERP to reporting views on a read replica, or to a warehouse via scheduled extraction. Power BI imports from that layer with incremental refresh, avoiding load on production.
For on-premise sources, the on-premises data gateway connects securely; cloud sources connect directly.
04Reliability
Dedicated read-only database user or service principal; Power BI workspace access managed through Entra ID groups.
Refresh failures alert the data owner; extraction jobs log row counts and errors.
Scheduled refreshes retry automatically; extraction jobs are idempotent by date range.
05 — Data mapping
| Power BI | ERP |
|---|---|
| ERP sales lines | FactSales |
| ERP stock moves | FactInventory |
| ERP partners | DimCustomer |
| ERP products | DimProduct |
| ERP analytic accounts | DimCostCentre |
06 — Automation
07 — Security
Read-only access, row-level security in Power BI, and no direct write access to the ERP.
