Google Apps Script

QuotaGuard puts two fixed IP addresses onto the target API's allowlist for your Google Apps Script integration. Because UrlFetchApp has no proxy field and the sandbox has no environment variables or sidecar, a small relay you host forwards each outbound call through QuotaGuard at the connectivity layer, so the target sees one of your two static IPs instead of Google's rotating egress. Trusted for static IP connectivity since 2013.

• Relay-Based Setup: Host a small relay function on AWS Lambda or a Google Cloud Function, set your QuotaGuard connection URL and a secret key, and point your Apps Script's UrlFetchApp.fetch() call at the relay with the target API passed in a header. Register your two static IPs with the target API once.
• The Target Sees Static IPs, Not Google Apps Script's: The relay forwards every request through QuotaGuard, so the target API sees your two static IPs. Apps Script's rotating egress and the relay host's own IP never reach the allowlist check.
• Multi-Platform Support: The relay deploys on AWS Lambda or Google Cloud Functions, and the same relay serves Bubble, Zapier, and any other platform that can call a URL but cannot set a proxy. One piece of infrastructure covers them all.
• Production-Grade Reliability: A load-balanced pair of static IPs with health checks and automatic failover. Both IPs go on the target's allowlist, and traffic routes through whichever responds.
• Shield for Regulated Data: For HIPAA, PCI-DSS, or SOC 2 workflows, QuotaGuard Shield uses SSL passthrough so QuotaGuard never decrypts the data flowing between the relay and the target API.

Gate note: You only need this when the API your Google Apps Script calls enforces IP allowlisting. If the target rejects requests from unregistered IPs, Apps Script's dynamic egress fails and you need the two static IPs. Calls to APIs with no IP allowlist do not need it.
