API Integration / Case Study 001

E-Commerce Inventory Synchronization System

Multi-platform real-time inventory management for distributed retail operations

99.7%
Sync Accuracy
4.2s
Average Latency
3
Integrated Platforms

Objective

Client operated three separate e-commerce platforms (Shopify storefront, WooCommerce wholesale portal, custom POS system) with manual inventory reconciliation occurring daily. Goal was to implement real-time bidirectional synchronization to eliminate stock discrepancies and reduce manual data entry overhead by 90%.

Technical Stack

Core Technologies

  • Python 3.11 (Flask framework)
  • Redis 7.0 (caching layer)
  • PostgreSQL 15 (transaction log)

API Integrations

  • Shopify Admin API v2024-01
  • WooCommerce REST API v3
  • Custom POS webhook endpoints

Implementation Logic

  1. 01
    Webhook Registration: Configured webhook listeners on all three platforms to capture inventory_updated events in real-time
  2. 02
    Event Processing: Python Flask API receives webhook payloads, validates signatures, and queues updates in Redis with 60-second deduplication window
  3. 03
    Conflict Resolution: Last-write-wins strategy with PostgreSQL transaction log maintaining audit trail of all inventory changes
  4. 04
    Propagation: Worker processes consume Redis queue and dispatch updates to other platforms via their respective APIs with exponential backoff retry logic

Operational Impact

Quantitative Results

  • Manual reconciliation time reduced from 2 hours/day to 5 minutes/week
  • Overselling incidents decreased from 12/month to 0.4/month
  • Average sync latency: 4.2 seconds (target: <5s)

System Reliability

  • 99.7% sync accuracy measured over 90-day period
  • Zero data loss incidents post-deployment
  • Automated alerting on sync failures >10s
Data Pipeline / Case Study 002

Financial Reporting Automation

Executive dashboard with automated daily financial aggregation

Data Sources
100%
Automation Rate

Objective

Executive team required daily financial dashboards aggregating data from Stripe (payments), QuickBooks (accounting), Salesforce (pipeline), Google Analytics (traffic), and internal database (operations). Existing process involved 6 hours of manual CSV exports and Excel manipulation. Target was full automation with <15 minute data freshness.

Technical Stack

Automation Platform

  • n8n (self-hosted, v1.19.4)
  • Python 3.11 (custom nodes)
  • Google Sheets API (dashboard output)

Data Sources

  • Stripe API v2024-01
  • QuickBooks Online API v3
  • Salesforce REST API v58.0

Implementation Logic

  1. 01
    Scheduled Triggers: n8n workflow executes daily at 6:00 AM UTC with cron scheduling and error notification to Slack
  2. 02
    Parallel Data Fetching: Five parallel branches query each API simultaneously with custom Python nodes handling authentication and pagination
  3. 03
    Data Transformation: Custom Python functions normalize currencies, calculate KPIs (MRR, CAC, LTV), and format for dashboard consumption
  4. 04
    Output Generation: Results written to Google Sheets template with conditional formatting and chart auto-refresh

Operational Impact

Efficiency Gains

  • Report generation time: 6 hours → 12 minutes (97% reduction)
  • 30 staff-hours/month reallocated to analysis vs. data entry
  • Zero manual errors in financial calculations post-implementation

Business Value

  • Executive team has real-time financial visibility before 9 AM daily
  • Enabled data-driven decision making with <24h lag time
  • 99.2% workflow success rate over 90-day measurement period
Workflow Automation / Case Study 003

Customer Onboarding Automation

End-to-end onboarding workflow with document processing and CRM integration

73%
Time Reduction
8 → 2.2
Days to Complete
0
Manual Touch Points

Objective

B2B SaaS client's onboarding process required manual collection of contracts, W9 forms, and compliance documentation, followed by data entry into HubSpot CRM and Airtable project management system. Average onboarding took 8 business days with 15+ manual touchpoints. Target was <3 days with zero-touch automation for standard customers.

Technical Stack

Core Platform

  • Zapier (Premium tier)
  • Python 3.11 (webhook handlers)
  • AWS Lambda (document processing)

Integrations

  • DocuSign API v2.1
  • HubSpot CRM API v3
  • Airtable API v0.1

Implementation Logic

  1. 01
    Deal Creation Trigger: HubSpot deal marked "Closed-Won" triggers Zapier workflow sending templated DocuSign envelope with contracts and forms
  2. 02
    Document Collection: Customer completes DocuSign remotely; webhook notifies Python endpoint which downloads signed PDFs to secure S3 bucket
  3. 03
    Data Extraction: AWS Lambda function with pytesseract OCR extracts key fields (company name, EIN, billing contact) from W9 and contract PDFs
  4. 04
    CRM/PM Update: Extracted data populates HubSpot deal properties and creates Airtable onboarding project with automated task assignments

Operational Impact

Process Improvements

  • Average onboarding time: 8.0 days → 2.2 days (73% reduction)
  • Manual touchpoints eliminated: 15 → 0 for standard onboardings
  • Data entry errors: 8% of records → <0.5% with OCR validation

Business Metrics

  • Customer satisfaction (onboarding NPS): +18 points post-automation
  • Sales team capacity: +40% (time freed from onboarding admin)
  • System uptime: 99.6% measured over 180-day period
