OpenRouter setup guide

Operational checklist

1. Verify keys are saved in Settings -> Integrations.
2. Run one low-cost test workflow after adding or rotating any key.
3. Monitor OpenRouter dashboard for cost and rate-limit behavior.
4. Document owner and rotation policy for your OpenRouter key.

Shopify OAuth setup

Shopify now uses OAuth connection instead of manually pasting Client ID and Client Secret.

1. Open Settings -> Integrations in MetaStack.
2. Enter your Shopify store domain (your-store or your-store.myshopify.com).
3. Click Connect Shopify.
4. Approve access on Shopify and return to MetaStack.

MetaStack requests read_products scope and stores the offline token encrypted at rest.

Required environment variables

• SHOPIFY_CLIENT_ID
• SHOPIFY_CLIENT_SECRET
• SHOPIFY_REDIRECT_URI
