Creators can add signed webhooks and API keys from the studio (endpoints under /api/me/webhook-endpoints and /api/me/api-keys when authenticated).
POST JSON body with type (e.g. form_submission, newsletter_subscribe), createdAt, and data. Verify header X-Reweyou-Signature as HMAC-SHA256 of the raw body with your endpoint secret.
Use Catch Hook or Custom Webhook modules pointing at your Reweyou webhook URL; map fields from the JSON body.
