Overview

Review the PartsSource Customer API documentation before getting started.

The Customer API is designed for external integrations with the PartsSource Marketplace Platform. It enables partners and customers to programmatically search the parts catalog, place orders, and manage user information within their authorized tenant.

Base URL

https://api.partssource.com/customer

Key Features

Multi-Tenant Architecture

The Customer API enforces strict tenant isolation. Each request is scoped to your organization, ensuring you can only access data belonging to your authorized tenant. Attempts to access resources outside your tenant will return a 403 Forbidden error.

Available Resources

Resource	Description
Catalog	Search parts and retrieve detailed product information including pricing options
Orders	Create new orders and retrieve order status and details
Users	Look up user profiles and search users within your organization

Authentication

All API requests require a valid JWT Bearer token obtained via the OAuth 2.0 client credentials flow.

curl -X POST https://auth.partssource.com/oauth2/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials" \
  -d "client_id=YOUR_CLIENT_ID" \
  -d "client_secret=YOUR_CLIENT_SECRET"

Include the token and API key in all requests:

curl -X GET https://api.partssource.com/customer/users/lookup?userId=12345 \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "x-api-key: YOUR_API_KEY"

For complete authentication details, see Authentication Overview.
