Third-party system name Cloudflare Workers (custom serverless proxy) Type of integration needed Direct API integration with Inspection Support Network (ISN) to programmatically: Create bookings / orders Query order data (Optionally) support future webhooks for order or booking status updates Required domains Please allow and enable API access for requests originating from: " https://misty-bush-8ec4.desmondthornton81.workers.dev " (This Worker acts as a secure proxy and handles authentication, routing, and validation.) Webhooks Webhooks are not required immediately, but I would like to know if ISN supports webhooks for booking or order status changes for future use. Additional technical context Authentication headers are being sent exactly as provided by ISN (Company Key, Access Key, Secret Key). Requests are currently reaching " goisn.net ", but responses indicate HTML / website surfaces (403 / non-JSON), not API endpoints. This suggests API access may need to be enabled for my account and/or that a different API base URL and prefix are required (e.g., "/api", "/v2", etc.). Once the correct API base URL, required prefix, and supported endpoints are confirmed or enabled, the integration on my side is ready to proceed immediately.
