This week brought three new integrations, critical security patches, and solid improvements across webhook reliability. Google Ads and Fathom AI are now available for workflows, Ashby webhooks finally work, and we patched some serious SSRF vulnerabilities. There's also a batch of fixes for block duplication, internal workflow calls, and various integrations.

Highlights

Pull campaign and ad metrics directly into your workflows using GAQL queries. Full OAuth support and input validation included. (#3360)

Ashby webhooks for real-time hiring events

Capture application submissions, stage changes, and offers as workflow triggers. Webhook setup and teardown happen automatically. (#3548)

Fathom AI Notetaker integration

Record and analyze meetings, extract action items, and match them to your CRM. (#3531)

Webhook deduplication and custom acknowledgment

Prevent duplicate processing with idempotency keys and configure how webhooks acknowledge receipt. (#3525)

SSRF security fixes for database and webhook tools

Blocked Server-Side Request Forgery attacks on database connections and webhook endpoints. Localhost is properly blocked for user-supplied URLs, and redirects are validated. (#3500)
