Freelance Quote API Simulation

Insurance APIs often require precision across multiple linked fields — projects, coverage options, certificate holders, and business rules must all align before a quote is generated. This project simulates that complexity through a fully structured API mock for freelance insurance quotes.

While there’s no live backend, the details of the API have been carefully built to reflect real-world quoting logic — and it’s fully testable using a public Postman Workspace. The goal was to replicate a realistic insurance submission flow and demonstrate how automation scripts can validate business rules, enforce structure, and simulate outcomes.

What This Project Covers

This simulated API accepts a structured JSON payload for freelance insurance quotes. It includes:

• Client information

• Up to three freelance projects (each with value, dates, and an eventId)

• Mapped certificate holders tied to those eventIds

• Dynamically selected coverages (e.g., liability, cyber, enhancements)

• Application questions that trigger inclusion/exclusion rules

Despite being a simulation, the system is modular, repeatable, and testable — making it a valuable way to showcase workflow automation and validation logic.

Project Design & Intent

The core idea behind this initiative was to:

• Replicate complex real-world business rules seen in quoting APIs

• Provide a safe, fully simulated environment where prospective employers can see how I think about request structure, validation, and data integrity

• Highlight the value of Postman as a test automation tool, not just a manual API client

This project mirrors how insurance carriers might process multi-project freelance submissions — enforcing date constraints, validating certificate holder alignment, and auto-including coverages based on responses.

Pre-Request Scripts:

• Generate realistic start/end dates

• Dynamically create UUIDs for each project’s eventId

• Ensure each certificate holder maps correctly to a project

• Randomize values across industries, coverage types, and application questions

Post-Request Scripts:

• Validate that the eventId links between projects and certificate holders match

• Confirm that policy start and end dates are derived from project ranges

• Enforce business rules (e.g., rented equipment is auto-added if equipmentRental = "Yes")

• Generate detailed error feedback when rules are broken

Sample Test Cases Included

• Valid multi-project quote with correct mappings

• Failing requests due to invalid email, mismatched eventId, or date issues

• Dynamic test generation using seeded environments

What It Shows

Even without a live backend, this API simulation demonstrates:

• Real-world insurance flows

• Use of Postman for automated request generation and validation

• Robust pre/post scripts to mirror production API behavior

• Combination of domain logic with testable payloads to create meaningful validation checkpoints
