When & Why to Use This Skill

This Claude skill provides a robust integration framework for Zoho Books and Zoho Inventory APIs, specifically optimized for the TSH Clients Console. It streamlines the management of products, orders, invoices, and payments while implementing high-performance OAuth token caching via Upstash Redis. By offering pre-configured API routes, error handling patterns for rate limits, and data fetching functions, it enables developers to build reliable e-commerce and ERP synchronization tools with minimal overhead.

Use Cases

  • Automated Inventory & Product Sync: Efficiently fetch and display real-time stock levels, product categories, and item details from Zoho Inventory.
  • Financial Document Management: Programmatically create and manage sales orders, invoices, payments, and credit notes within the Zoho Books ecosystem.
  • Secure OAuth Token Orchestration: Implement a multi-layer caching strategy using Memory and Upstash Redis to handle Zoho's authentication and prevent rate-limiting issues.
  • Technical Debugging & Monitoring: Utilize specialized debug commands and error-handling patterns to troubleshoot API connectivity, token expiration, and stock display logic.
  • Next.js API Integration: Rapidly deploy serverless API routes that interact with Zoho endpoints using optimized fetch patterns and revalidation tags.

Zoho API Integration

Quick Reference

API Base URL
Zoho Inventory https://www.zohoapis.com/inventory/v1
Zoho Books https://www.zohoapis.com/books/v3

Organization ID: 748369814

Code Files

File Purpose
src/lib/zoho/client.ts OAuth client, token caching, zohoFetch
src/lib/zoho/products.ts Products, stock extraction
src/lib/zoho/price-lists.ts Price list constants and fetching
src/lib/zoho/customers.ts Customer lookup by email
src/lib/zoho/orders.ts Sales orders
src/lib/zoho/invoices.ts Invoices
src/lib/zoho/payments.ts Payments
src/lib/zoho/credit-notes.ts Credit notes

Using zohoFetch

import { zohoFetch } from '@/lib/zoho/client';

// GET request
const data = await zohoFetch('/inventory/v1/items', {
  params: {
    organization_id: process.env.ZOHO_ORGANIZATION_ID,
    page: 1,
    per_page: 100,
  },
});

// Single item with locations
const item = await zohoFetch(`/inventory/v1/items/${itemId}`, {
  params: { organization_id: process.env.ZOHO_ORGANIZATION_ID },
});

Token Caching (CRITICAL)

Memory Cache → Upstash Redis → Zoho OAuth Refresh
              (50-min TTL)    (rate limit: 10s guard)

If all prices show "Contact for price", check:

  1. Upstash env vars in Vercel
  2. UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN
  3. Run: curl https://www.tsh.sale/api/debug/token

Common Endpoints

Inventory API

GET /items                      # List products
GET /items/{id}                 # Single product (includes locations)
GET /categories                 # List categories
GET /pricebooks/{id}            # Pricebook with items

Books API

GET /contacts                   # List customers
GET /salesorders                # Sales orders
GET /invoices                   # Invoices
GET /customerpayments           # Payments
GET /creditnotes                # Credit notes

Caching with unstable_cache

import { unstable_cache } from 'next/cache';

const getCachedProducts = unstable_cache(
  async () => await fetchProducts(),
  ['products'],
  { revalidate: 3600, tags: ['products'] }
);

Revalidate cache:

curl "https://www.tsh.sale/api/revalidate?tag=products&secret=tsh-revalidate-2024"

Error Handling Pattern

try {
  const data = await zohoFetch('/inventory/v1/items', { ... });
} catch (error) {
  if (error.message.includes('401')) {
    // Token expired - auto-refreshes
  } else if (error.message.includes('429')) {
    // Rate limited - wait and retry
  }
}

Creating New API Route

// src/app/api/zoho/[resource]/route.ts
import { NextResponse } from 'next/server';
import { zohoFetch } from '@/lib/zoho/client';

export async function GET(request: Request) {
  const data = await zohoFetch('/inventory/v1/items', {
    params: {
      organization_id: process.env.ZOHO_ORGANIZATION_ID,
    },
  });

  return NextResponse.json(data);
}

Rate Limits

API Limit
OAuth Refresh ~100/minute
Inventory API 100/minute
Books API 100/minute
