Oracle APEX Database and API Sync -- 2
Budget: $30 – $250 USD
Overview
-- We are seeking a skilled Oracle APEX developer to help implement an efficient and reliable synchronization mechanism between our Oracle database and external APIs.
-- The goal is to automatically trigger API calls whenever specific records in our database (e.g., Products, Customers, Orders) are created, updated, or deleted.
System Context
-- Our application is built on Oracle APEX.
-- We want to create listeners or triggers that act directly on the underlying Oracle database tables.
-- Once a change is detected, the system should automatically send the updated data to a designated external API endpoint.
Requirements
Database Events to Monitor:
-- INSERT, UPDATE, DELETE on:
-- Products
-- Customers
-- Orders
Integration Logic:
-- On any of these events:
-- Either trigger individual endpoints per entity (e.g. /api/products/update)
-- Or trigger a single generic API with type and payload (e.g., /api/sync)
-- Developer should recommend the most reliable and scalable structure.
Data Format & Transport:
-- Send changes as JSON payloads.
-- Transport over secure HTTP (HTTPS).
-- Include proper authentication.
Reliability & Fallbacks:
-- Log failures and provide a retry strategy to ensure data sync.
-- Avoid impacting APEX app performance
-- Ability to handle race conditions.
Expected Deliverables
-- Trigger scripts or packages integrated within Oracle APEX backend.
-- API execution logic with logging and fallback handling.
-- Technical documentation covering:
-- Setup and installation
-- API call structure
-- Fallback and error handling
-- Performance and security recommendations
Ideal Freelancer
-- Strong understanding of Oracle APEX and PL/SQL triggers
-- Strong understanding of REST APIs
-- Familiar with data sync, logging, retry mechanisms
-- Clear communication and documentation skills
