How to integrate WooCommerce with OpenClaw

You can integrate WooCommerce with OpenClaw by building a ClawHub skill that calls the WooCommerce REST API for on-demand actions (read/update orders, products, customers) and by receiving WooCommerce webhooks through an externally hosted HTTP endpoint that forwards events into your integration pipeline (skill invocation, queue, or backend). Store WooCommerce credentials (consumer key/secret or OAuth tokens) in ClawHub’s secret/configuration store, validate all webhooks with the WooCommerce HMAC signature, keep any stateful or long-running processes outside the agent runtime (database, queue, scheduler), and instrument logging and retries so you can debug API responses, credentials, and invocation behavior.

 

Overview — how the pieces fit

 
  • Skill (ClawHub): Code that performs on-demand WooCommerce calls (GET/POST/PUT to /wp-json/wc/v3/\*). The skill runs inside the agent runtime and should be stateless or store minimal ephemeral state.
  • Secrets and auth: Consumer key/secret or OAuth tokens are stored in ClawHub’s secret/config system (environment variables, secret store). Always require TLS for API calls.
  • Webhooks: WooCommerce pushes order/product events to an HTTP endpoint you host publicly. That endpoint validates the HMAC signature and then forwards events into your integration pipeline (for example, by pushing into a queue or making an authenticated call to your backend that triggers a ClawHub skill invocation).
  • External systems: Persisted state, retry logic, durable queues, and scheduled jobs live outside the agent (database, Redis, SQS, cron), because an agent runtime is not a reliable long-term host.
  • Observability: Logs and API traces must be available both in your backend and in ClawHub so you can inspect failed calls and HTTP responses.

 

Step-by-step integration plan

 
  • 1) Create WooCommerce API credentials.
    • In WooCommerce admin: create a REST API key (consumer key and consumer secret) with appropriate read/write permissions for the resources you need (orders, products, customers).
    • Decide on auth method: consumer key/secret (recommended over HTTPS) is most common; OAuth1.0a is available for older setups. If you must use user-level OAuth, implement standard OAuth flows externally and store tokens securely.
  • 2) Prepare a skill in ClawHub.
    • Write the skill code to call WooCommerce REST endpoints using HTTPS. Keep the skill stateless: return results to the caller and push stateful changes to your external database if needed.
    • Use environment variables for credentials (e.g., process.env.WC_CONSUMER_KEY, process.env.WC_CONSUMER_SECRET).
    • Upload/configure this skill through ClawHub (install/enable the skill and supply secrets using the platform’s secret/config UI or API).
  • 3) Receive and validate webhooks externally.
    • Host a public HTTPS webhook endpoint (your own web server, serverless function, or an authenticated webhook relay). Register its URL in WooCommerce (WooCommerce → Settings → Advanced → Webhooks).
    • Validate incoming webhooks using the header X-WC-Webhook-Signature (WooCommerce sends a base64 HMAC-SHA256 using the webhook secret). Reject invalid signatures before processing.
    • Forward validated events to your integration pipeline: either push into a durable queue (recommended for retries/backpressure) or call your backend that triggers a ClawHub skill invocation.
  • 4) Implement error handling, retries and idempotency.
    • For webhook processing, respond quickly (HTTP 200) after enqueuing work. Let a worker process the event and call WooCommerce or ClawHub as needed.
    • Use idempotency keys on operations that modify WooCommerce state (so retries don’t create duplicates).
    • Implement exponential backoff and dead-lettering for API failures.
  • 5) Test thoroughly before production.
    • Use curl or Postman to exercise the WooCommerce REST API with your credentials. Use a webhook testing tool (ngrok, webhook.site) or temporary endpoint to confirm signature validation.
    • Run integration tests for the skill in a staging ClawHub environment and validate logs and full request/response traces.

 

Example code — calling WooCommerce REST API from a skill (Node.js)

 
// Example: fetch recent orders from WooCommerce
// <b>//</b> This code uses global env vars for secrets: WC_CONSUMER_KEY and WC_CONSUMER_SECRET
import fetch from 'node-fetch';

export async function listRecentOrders() {
  const key = process.env.WC_CONSUMER_KEY;
  const secret = process.env.WC_CONSUMER_SECRET;
  const base = process.env.WC_BASE_URL; // e.g. "https://store.example.com"
  if (!key || !secret || !base) {
    throw new Error('Missing WooCommerce credentials or base URL');
  }

  const auth = Buffer.from(`${key}:${secret}`).toString('base64');
  const url = `${base.replace(/\/$/,'')}/wp-json/wc/v3/orders?per_page=20`;

  const res = await fetch(url, {
    method: 'GET',
    headers: {
      'Authorization': `Basic ${auth}`,
      'Accept': 'application/json'
    }
  });

  if (!res.ok) {
    const text = await res.text();
    throw new Error(`WooCommerce API error ${res.status}: ${text}`);
  }

  const orders = await res.json();
  return orders;
}

 

Example code — webhook receiver and signature verification (Node.js/Express)

 
// Simple webhook receiver that verifies X-WC-Webhook-Signature
import express from 'express';
import crypto from 'crypto';

const app = express();
// <b>//</b> Raw body needed to compute signature, express.json won't do raw by default for HMAC
app.use(express.raw({ type: '*/*' }));

app.post('/webhook/woocommerce', async (req, res) => {
  const secret = process.env.WC_WEBHOOK_SECRET;
  const sig = req.headers['x-wc-webhook-signature'];
  const rawBody = req.body; // Buffer

  if (!secret || !sig) {
    return res.status(400).send('Missing secret or signature');
  }

  const hmac = crypto.createHmac('sha256', secret)
    .update(rawBody)
    .digest('base64');

  if (!crypto.timingSafeEqual(Buffer.from(hmac), Buffer.from(sig))) {
    return res.status(401).send('Invalid signature');
  }

  const payload = JSON.parse(rawBody.toString('utf8'));
  // <b>//</b> Enqueue or forward the payload for processing (durable queue recommended)
  // e.g., push to SQS/Redis, or call your backend to trigger ClawHub skill
  // await enqueueEvent(payload);

  return res.status(200).send('OK');
});

app.listen(3000);

 

Security, reliability, and production practices

 
  • Secrets: Put consumer keys, webhook secrets, and OAuth client secrets into ClawHub secret storage (or equivalent environment variables) — never commit them to source control.
  • Use HTTPS everywhere: WooCommerce credentials must be used over TLS; webhook endpoints must be HTTPS.
  • Webhook validation: Always validate the HMAC signature (X-WC-Webhook-Signature). Reject and log bad signatures.
  • Externalize state: Long-lived transactions (order state, retries, reports) must live in an external DB or durable queue. Don’t rely on agent runtime for persistence.
  • Rate limits and pagination: Respect WooCommerce rate limits; implement pagination when listing resources and consider incremental syncs using updated\_after timestamps.
  • Idempotency: Use idempotency keys for create/update operations when you may retry a request.
  • Least privilege: Create API keys scoped to the actions you need (read-only for reporting, read-write for fulfillment endpoints).

 

Debugging checklist

 
  • Credentials & scopes: Verify consumer key/secret are correct and have the right permissions in WooCommerce.
  • SSL/TLS: Confirm HTTPS endpoints and no mixed-content issues.
  • Signature verification: If webhooks are rejected, check raw payload encoding (must compute HMAC over raw bytes) and time syncing (rarely relevant for HMAC-SHA256 but still check timestamps).
  • API responses: Log full response bodies and HTTP status codes for failed calls. Check for descriptive error messages from WooCommerce (rate limit, permission errors).
  • Invocation path: Confirm the webhook reaches your public endpoint (use request logs/ngrok) and that the event is enqueued or forwarded to the worker that triggers the ClawHub skill.
  • Logs: Combine ClawHub skill logs and your backend logs to trace end-to-end flows.
  • Local testing: Use curl or Postman to reproduce failing calls, and run end-to-end tests in a staging environment before deploying to production.

Troubleshooting WooCommerce and OpenClaw Integration

1

OpenClaw API key authentication failure

 

Direct answer

 

If an OpenClaw API key authentication fails, first confirm the key is loaded into the agent runtime (env var or secret), the skill/agent has permission to read it, and the request uses the exact header your integration expects (common patterns: Authorization: Bearer <KEY> or x-api-key: <KEY>). Reproduce the call locally, inspect runtime logs and API responses (401/403) and rotate/regenerate the key if it might be revoked.

 

Quick checklist

 
  • Env var present in the runtime and spelled correctly.
  • Skill permission to access the secret in ClawHub/runtime.
  • Header format exactly matches the API’s requirement.
  • Logs show header sent and upstream error code/message.

 

Example requests

 
# <b>//</b> reproduce with curl
curl -i -H "Authorization: Bearer $OPENCLAW_API_KEY" https://api.example.com/endpoint
// <b>//</b> node fetch example
fetch('https://api.example.com/endpoint',{
  method:'GET',
  headers:{ 'Authorization': `Bearer ${process.env.OPENCLAW_API_KEY}` }
});

2

OpenClaw webhooks not received or signature verification failing

Direct answer: Webhooks not arriving or failing signature checks usually come from unreachable endpoints, misconfigured webhook secrets, transformed request bodies, clock skew, or middleware that reads the body before verification. Fix by confirming delivery on the provider, validating public URL/SSL and firewall, matching the exact secret and signature algorithm, and logging raw headers + raw body for comparison.

 

Verify connectivity & delivery

 
  • Check provider delivery logs for status and retries.
  • Ensure the OpenClaw skill endpoint is public, HTTPS, and not behind a blocked firewall or NAT.
  • Test with curl or ngrok to reproduce payloads locally.

 

Debug signature verification

 
  • Match secret & algorithm exactly — providers vary (HMAC SHA variants, RSA).
  • Log raw body and signature header before parsing or middleware modifies the body.
  • Account for timestamps and replay windows if provider signs with timestamps.
// Example HMAC SHA256 verification in Node.js
const crypto = require('crypto'); // compute signature from raw body and secret
function verify(rawBody, secret, signatureHeader) {
  // compute expected signature
  const expected = 'sha256=' + crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
  return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signatureHeader));
}

3

WooCommerce orders not syncing / incorrect status mapping

Direct answer: most WooCommerce sync problems come from webhook misconfiguration, permissions/auth failures, or mismatched status mappings inside the skill. Verify webhooks deliver to the OpenClaw skill endpoint, confirm API keys/OAuth are set in environment variables, inspect delivery logs and your skill’s mapping logic so Woo status values map to the exact states your agent expects.

 

Diagnose quickly

 
  • Check Woo webhooks: topics (order.created/updated), URL, secret, delivery logs and responses.
  • Auth & env: consumer key/secret or OAuth token must match skill env vars and have REST permissions.
  • Logs: review OpenClaw skill execution traces, HTTP response codes, and webhook retries.

 

Fix mapping

 
  • Map Woo statuses explicitly (pending/processing/completed/cancelled/refunded/failed) to your agent states; use the exact status field from payload.
  • Handle idempotency and late updates; retry failed webhooks and reconcile via REST GET /orders/{id} when unsure.

4

WooCommerce product/variant sync errors — SKU or variant ID mismatches

Direct answer: SKU or variant ID mismatches usually occur because the external SKU used to identify a WooCommerce variation doesn't match the SKU or variation_id stored in your source system or because your sync uses the wrong lookup key (e.g., variation_id vs SKU). Fix by aligning lookup keys, reconciling records, and verifying API payloads and credentials before retries.

 

Troubleshooting steps

 
  • Verify lookup: confirm whether your sync uses SKU or WooCommerce variation_id and make them consistent.
  • Inspect API payloads/logs: check REST responses, 404/400 errors, and webhook deliveries in the OpenClaw runtime and ClawHub logs.
  • Reconcile data: run a one-time audit by matching SKUs; update missing or duplicate SKUs in source or WooCommerce.
  • Permissions & auth: ensure API keys/OAuth tokens and env vars are correct and have write scope for variations.
