--- title: Zoho Inventory API Integration on Truto slug: zohoinventory category: E-Commerce canonical: "https://truto.one/integrations/detail/zohoinventory/" --- # Zoho Inventory API Integration on Truto **Category:** E-Commerce **Status:** Generally available ## Unified APIs ### Unified E-Commerce API - **Customers** — The customer represent a customer in E-Commerce. - **Orders** — The order represent an order in E-Commerce. - **Products** — The product represent a product in E-Commerce. ## How it works 1. **Link your customer's Zoho Inventory account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Zoho Inventory.** The Proxy API is a 1-to-1 mapping of the Zoho Inventory API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Sync product catalogs and stock levels from Zoho Inventory into your B2B ordering platform** — If you run a wholesale or B2B commerce platform, your merchant users need their Zoho Inventory product catalog—including real-time stock quantities, pricing, and variants—reflected in your app. Pulling Products via a unified API lets you display accurate availability without building Zoho-specific pagination, auth, or item-group logic. - **Push orders from your platform directly into your users' Zoho Inventory accounts** — Whether you're a marketplace, a field-service tool, or a custom storefront builder, writing Orders back into Zoho Inventory closes the loop on fulfillment. Your users avoid double data entry and their committed stock updates instantly, preventing overselling across channels. - **Pull historical orders and customer data to power analytics and forecasting** — SaaS companies building demand planning, purchasing automation, or business intelligence dashboards need access to historical sales velocity and customer segments. Reading Orders and Customers from Zoho Inventory gives your models the raw data they need to generate actionable recommendations for merchants. - **Keep customer records in sync between your platform and Zoho Inventory** — If your SaaS manages CRM, loyalty, or post-purchase workflows, syncing Customers ensures your users' contact details, billing addresses, and payment terms stay consistent across systems without manual reconciliation. - **Enable returns and inventory reconciliation workflows** — Post-purchase platforms handling RMAs or warranty claims need to validate original order line items and update inventory when returned goods are restocked. Reading Orders and writing adjustments back through a single integration layer eliminates fragile custom code. ## What you can build - **Real-time product catalog sync with stock levels** — Pull your users' Zoho Inventory items—including SKUs, pricing, variants, and current stock on hand—into your app so their catalog stays accurate across platforms. - **Automated order creation from external sales channels** — Write Sales Orders into Zoho Inventory whenever a transaction occurs in your platform, instantly allocating inventory and kicking off the fulfillment workflow. - **Customer directory import and sync** — Import Zoho Inventory contacts into your app with billing addresses, payment terms, and tax details so your users can manage accounts without switching tools. - **Historical order ingestion for sales analytics** — Bulk-read past orders to build sales velocity dashboards, cohort analyses, or AI-driven reorder recommendations inside your product. - **Unified multi-source e-commerce data layer** — Let your users connect Zoho Inventory alongside other e-commerce platforms through one consistent Customers, Orders, and Products schema—no per-integration mapping required. ## FAQs ### How does authentication work for Zoho Inventory? Zoho Inventory uses OAuth 2.0. Truto handles the full OAuth flow—including token refresh—so your end users simply authorize access through a consent screen and you never manage credentials directly. ### What data can I access through the Unified E-Commerce API for Zoho Inventory? The Unified E-Commerce API exposes three core resources: Customers (contacts, addresses, payment terms), Orders (sales orders with line items, statuses, and pricing), and Products (items with SKUs, stock quantities, pricing, and variants). These map to Zoho Inventory's /contacts, /salesorders, and /items endpoints respectively. ### Are there specific Truto tools available for Zoho Inventory today? Zoho Inventory tools are built on request. If you need capabilities beyond the Unified E-Commerce API—such as item adjustments, transfer orders, or purchase order creation—Truto can build custom tools scoped to your use case. ### How does Truto handle Zoho Inventory's API rate limits? Zoho Inventory enforces organization-level rate limits that vary by plan. Truto manages request throttling and retry logic automatically so your integration doesn't hit 429 errors or require custom backoff code. ### Does Zoho Inventory support multi-location inventory, and can I access that data? Yes, Zoho Inventory tracks stock across multiple warehouses and locations. Product stock quantities are available per location through the API. If your use case requires location-level granularity beyond the unified schema, Truto can expose that through custom tools. ### Can I access product variants and grouped items? Zoho Inventory handles variants through Item Groups. The Products resource in the Unified API maps to individual items, including variant-level data like SKU, price, and stock. Composite items and item groups can be accessed through custom tools if needed.
