The Challenge

Where This Started.

Before

  • Three disconnected systems: CRM, ERP, and a payment platform
  • Manual data reconciliation across every system
  • No single source of truth for customer or order data

After

  • One secure integration layer inside WordPress
  • REST, SOAP, and OAuth2 unified behind one consistent interface
  • Consistent logging and error handling across every connection

Business Impact

Why It Mattered

Fragmented systems mean fragmented data: the same customer or order existing in three places, none of them fully in sync. That gap grows more expensive to manage as a business scales.

Engineering Approach

How We Approached It

Rather than building a one-off connector per system, the integration was designed as a single secure layer inside WordPress capable of speaking REST, SOAP, and OAuth2 — so future systems could be added to the same layer instead of requiring another bespoke connector.

Architecture

How It's Wired Together.

WordPress Integration Layer
CRM — OAuth2
ERP — SOAP
Payment Platform — REST

A unified integration service inside WordPress brokers all outbound and inbound calls, normalising each external system's data shape into one consistent internal format before anything touches WooCommerce or WordPress data.

Implementation

What We Built

Built secure OAuth2 authentication against the CRM, a SOAP client for the legacy ERP, and REST endpoints for the payment platform — all routed through the same internal service layer with consistent logging and error handling.

Technical Highlights

What Made This Work.

  • One integration layer instead of three disconnected point-to-point connections

  • Secure OAuth2, SOAP, and REST support inside a single WordPress service

  • Consistent logging and error handling across every connected system

Results

The Outcome.

Three separate, manually-reconciled systems unified into one integration layer

Customer and order data now flows automatically between systems that previously required manual reconciliation, removing a recurring operational burden.

Lessons Learned

What This Taught Us

Building one flexible integration layer up front — rather than a bespoke connector per external system — meant each additional system after the first two took a fraction of the engineering time.
