Inventory System Overview

Our inventory system is architected to facilitate detailed tracking and management of car parts categorized hierarchically by:

  • Brand (e.g., Toyota, Ford)
  • Model Year (e.g., 2018, 2022)
  • Part Category (e.g., brakes, engine)
  • Individual Part

This categorization enables precise filtering and retrieval of parts compatible with specific car brand-model year combinations.

Core Features:

  • Hierarchical categorization supporting brand and model year filtering
  • Real-time update capabilities for stock, pricing, descriptions
  • Bulk update endpoints for large-scale inventory management
  • Pagination and filtering to optimize data retrieval performances
  • Secure token-based authentication with rate limiting

Authentication & Rate Limiting

All requests require authentication via an API token included in the request header:

Authorization: Bearer YOUR_API_TOKEN

Obtain and manage your API tokens through our Developer Portal.

Rate Limits:

Plan Requests per Hour Reset Interval
Free 500 Hourly
Standard 5,000 Hourly
Enterprise Custom Custom

Exceeding limits results in HTTP 429 responses. Implement retry logic with exponential backoff to handle rate limit errors gracefully.


API Endpoints

Brand Management

Brands are the primary identifier for car parts.

  • List All Brands
    GET /brands
    Retrieves all car brands available.

  • Get Brand Details
    GET /brands/{brandId}
    Fetch detailed information on a specific brand.

  • Create a New Brand
    POST /brands
    Request body:

    {
      "name": "Tesla",
      "description": "Electric vehicle manufacturer"
    }
    

    Creates a new brand entry.

Model Year Management

Model years are nested under brands to specify part compatibility.

  • List Model Years for a Brand
    GET /brands/{brandId}/model-years
    Retrieves available model years for the brand.

  • Add Model Year to a Brand
    POST /brands/{brandId}/model-years
    Request body:

    {
      "year": 2024
    }
    

    Adds a new model year for the brand.

  • Delete a Model Year
    DELETE /brands/{brandId}/model-years/{modelYearId}
    Removes a model year from the brand.

Car Parts Management

Parts are assigned at the intersection of brand and model year, and grouped by categories.

  • List Parts by Brand and Model Year
    GET /brands/{brandId}/model-years/{modelYearId}/parts
    Optional query parameters:

    • category (e.g., "engine", "brakes")
    • limit (default 50)
    • offset (pagination)
  • Get Part Details
    GET /parts/{partId}

  • Add New Part
    POST /brands/{brandId}/model-years/{modelYearId}/parts
    Request body example:

    {
      "name": "Oil Filter",
      "category": "engine",
      "sku": "OF-76543",
      "stock": 150,
      "price": 15.00,
      "description": "Oil filter for 2011 Toyota Camry"
    }
    
  • Update Part Details or Stock
    PATCH /parts/{partId}
    Supports partial updates. For example:

    {
      "stock": 130,
      "price": 14.50,
      "description": "Updated oil filter for 2011 Toyota Camry"
    }
    
  • Delete Part
    DELETE /parts/{partId}

  • Bulk Upload Parts
    POST /parts/bulk-upload
    Accepts a JSON array of parts objects to efficiently add or update multiple parts.


Data Structures & Categorization Scheme

  • Brand

    • id (integer)
    • name (string)
    • description (optional string)
  • Model Year

    • id (integer)
    • brandId (integer)
    • year (integer)
  • Part

    • id (integer)
    • brandId (integer)
    • modelYearId (integer)
    • name (string)
    • category (string) — predefined values include: ["brakes", "engine", "suspension", "electronics", "transmission"]
    • sku (string)
    • stock (integer)
    • price (float) — in USD
    • description (optional string)
    • createdAt (ISO-8601 timestamp)
    • updatedAt (ISO-8601 timestamp)

This normalized structure ensures fast, reliable queries by brand and year, improving inventory accuracy.


Use Case Examples

1. Fetch Suspension Parts for 2019 Ford Models

GET /brands/2/model-years/2019/parts?category=suspension&limit=20
Authorization: Bearer YOUR_API_TOKEN

2. Add Model Year 2023 to Toyota

POST /brands/1/model-years
Content-Type: application/json
Authorization: Bearer YOUR_API_TOKEN

{
  "year": 2023
}

3. Update Stock Quantity for a Part

PATCH /parts/101
Content-Type: application/json
Authorization: Bearer YOUR_API_TOKEN

{
  "stock": 90
}

4. Bulk Upload Multiple Parts

POST /parts/bulk-upload
Content-Type: application/json
Authorization: Bearer YOUR_API_TOKEN

[
  {
    "brandId": 1,
    "modelYearId": 3,
    "name": "Spark Plug",
    "category": "engine",
    "sku": "SP-9001",
    "stock": 50,
    "price": 10.00,
    "description": "Spark plug for 2012 Toyota Camry"
  },
  {
    "brandId": 1,
    "modelYearId": 3,
    "name": "Fuel Pump",
    "category": "engine",
    "sku": "FP-9910",
    "stock": 20,
    "price": 150.00
  }
]

Error Handling Schema

All errors return a JSON response with an error object containing code and message fields.

Status Code Meaning Description
400 Bad Request Malformed payload or invalid data
401 Unauthorized Invalid or missing API token
404 Not Found Resource does not exist
409 Conflict Duplicate or conflicting entry
429 Too Many Requests Rate limit exceeded
500 Internal Server Error Unexpected server error

Example:

{
  "error": {
    "code": 404,
    "message": "Brand with ID 99 not found"
  }
}

Best Practices for Integration

  • Always paginate large data responses using limit and offset parameters to improve performance.
  • Cache brand and model year data locally as these update infrequently.
  • Validate input payloads client-side to minimize 400 errors.
  • Use bulk endpoints when updating or adding multiple parts simultaneously.
  • Keep your API tokens secure and never expose them in public repositories or client-side code.
  • Implement retry logic with exponential backoff when receiving 429 errors due to rate limiting.
  • Monitor and automate stock level adjustments to prevent overselling and stockouts.
