Short answer: Build a small, secure connector service that performs Zoho Inventory OAuth2 (keeps the refresh token and does token refresh), exposes a minimal authenticated REST surface the OpenClaw skill can call, and configure the OpenClaw skill via ClawHub with the service URL and a service key. Keep long‑lived secrets and retries outside the agent runtime, validate webhooks from Zoho in the connector, and ensure ClawHub environment variables include the Zoho organization ID and scopes used. Use Zoho’s documented OAuth token endpoints and Inventory REST APIs from the connector; have the skill call your connector (not Zoho directly) so the agent stays stateless and secure.
https://accounts.zoho.com/oauth/v2/auth?scope=AaaServer.profile.Read,ZohoInventory.items.ALL&client_id=YOUR_CLIENT_ID&response_type=code&access_type=offline&redirect_uri=https://your-connector.example.com/oauth/callback// After the user consents, Zoho will redirect to your connector callback with ?code=AUTH\_CODE
curl -X POST "https://accounts.zoho.com/oauth/v2/token" \\ -d "grant_type=authorization_code" \\ -d "client_id=YOUR_CLIENT\_ID" \\ -d "client_secret=YOUR_CLIENT\_SECRET" \\ -d "redirect\_uri=https://your-connector.example.com/oauth/callback" \\ -d "code=AUTH\_CODE"// The response contains access_token and refresh_token. Store the refresh\_token securely in your connector.

If Zoho Inventory OAuth2 refresh fails when your OpenClaw skill calls it, the direct fixes are: log the exact Zoho error, verify the stored refresh token + client credentials and token endpoint, handle expired/revoked refresh tokens by prompting reauth, ensure your runtime clock and retry/backoff logic are correct, and persist new tokens into the credential store ClawHub/OpenClaw uses before retrying requests.
Check logs and Zoho response (invalid_grant, invalid_client). Validate client_id, client_secret, refresh_token, grant_type=refresh_token, and redirect_uri. Persist returned access_token/refresh_token atomically in your credential store. If refresh token is revoked, require user re-auth. Add retries with exponential backoff and clock sync.
// refresh Zoho token and persist (Node.js, realistic HTTP request)
const res = await fetch('https://accounts.zoho.com/oauth/v2/token', {
method: 'POST',
headers: {'Content-Type':'application/x-www-form-urlencoded'},
body: new URLSearchParams({
client_id, client_secret, refresh_token, grant_type:'refresh_token'
})
});
const data = await res.json();
// store data.access_token and data.refresh_token in your secure credential store used by ClawHub

Direct answer: Syncs stop because the integration and Zoho use different primary identifiers — Zoho provides an SKU while the OpenClaw skill is matching on product_id. The fix is to choose a canonical key, add an explicit SKU↔product_id mapping in your skill configuration or lookup logic, normalize incoming webhooks, and run a reconciliation that populates the missing IDs.
One system emits SKU, the other expects product_id. Without a mapping, the skill treats items as new or missing.
// find existing product by product_id or fallback to SKU
async function findProduct(apiUrl, token, item) {
// try by product_id
let res = await fetch(`${apiUrl}/products/${item.product_id}`, { headers:{ Authorization:`Bearer ${token}` }});
if (res.ok) return res.json();
// fallback: search by SKU
res = await fetch(`${apiUrl}/products?sku=${encodeURIComponent(item.sku)}`, { headers:{ Authorization:`Bearer ${token}` }});
return res.ok ? (await res.json())[0] : null;
}

Inventory discrepancies usually come from incorrect warehouse_id mapping, missing or duplicate stock_adjustment records, timing/concurrency during syncs, or differences in reserved vs available quantities. Fix by verifying mappings, replaying or creating idempotent stock adjustments targeted to the correct warehouse_id, and reconciling counts with an audited compare-and-fix job.

Short answer: Most failures come from one of three places: the webhook endpoint in your OpenClaw skill isn’t reachable or not routing raw body correctly, signature verification using the stored secret fails, or Zoho’s delivery is being rate-limited/quickly retried. Fix the endpoint, verify HMAC using the env secret, return a fast 2xx, and handle retries/idempotency.
// Express example: verify HMAC SHA256
const crypto = require('crypto');
app.post('/webhook', express.raw({type:'application/json'}), (req,res)=>{
const secret = process.env.WEBHOOK_SECRET; // from ClawHub
const sig = req.get('X-Signature'); // provider header
const digest = 'sha256='+crypto.createHmac('sha256',secret).update(req.body).digest('hex');
if(!crypto.timingSafeEqual(Buffer.from(digest), Buffer.from(sig||''))){ return res.status(401).end(); }
// process and respond quickly
res.status(200).end();
});
