No. You generate a webhook URL inside the app, paste it into any system that can send an HTTP request, and pick your new trigger inside Shopify Flow. Zero code. ### How are incoming webhooks authenticated? Choose between HMAC-SHA256 signatures (industry standard) or a static header token. Both are configurable per trigger. Requests without valid auth are rejected before they touch Flow. ### Where are payloads stored? All payloads, headers, and response metadata are stored on Google Cloud in the EU (eu-west-1), encrypted at rest with Google Cloud KMS. Retention depends on your plan. ### Does it work with n8n, Make, Zapier? Yes. Any tool that can send an HTTP POST works. We ship templates for n8n, Make and Zapier in the docs. ### Is the app GDPR-compliant? Yes. EU-only data residency, signed DPA on request, no third-party tracking on this site.
