zoho-api

Zoho Books and Zoho Inventory API integration for TSH Clients Console. Use when: (1) Creating new API routes that call Zoho endpoints (2) Debugging API errors, token issues, or rate limits (3) Adding new Zoho data fetching functions (4) Understanding OAuth token caching with Upstash Redis (5) Working with products, orders, invoices, payments, or credit notes (6) Troubleshooting "Contact for price" or stock display issues

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

Using zohoFetch

typescript
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

typescript
import { unstable_cache } from 'next/cache';

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

Revalidate cache:

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

Error Handling Pattern

typescript
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

typescript
// 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

Debug Commands

bash
# Check token
curl "https://www.tsh.sale/api/debug/token"

# Check prices
curl "https://www.tsh.sale/api/debug/prices"

# Check stock
curl "https://www.tsh.sale/api/debug/stock"

# Revalidate cache
curl "https://www.tsh.sale/api/revalidate?tag=all&secret=tsh-revalidate-2024"
