Freshworks CRM ↔ Customer Database Sync

Sales teams work inside Freshworks CRM while billing, entitlements, and support history live in an operational database. Without a sync layer, both sides drift: a renewed contract shows as churned in CRM, a corrected email address never reaches the product, and every report has to be caveated. Point-to-point scripts make it worse — each side overwrites the other with whichever job ran last.

• A Freshworks integration built on the CRM REST API for reads and writes, with OAuth 2.0 credential rotation, per-endpoint rate-limit budgeting, and exponential back-off with jitter on 429 responses.
• A field-level mapping registry that declares ownership per attribute — CRM owns lifecycle stage and owner, the database owns entitlement, plan, and invoice state — so conflicts are resolved by declared authority rather than last-write-wins.
• Change-data-capture on the database side plus Freshworks webhooks on the CRM side, both landing in an idempotent event queue keyed on external id and event signature so replays and duplicates are no-ops.
• A reconciliation sweep that re-compares both stores on a schedule, reports drift by field, and can replay a single record, a segment, or the full estate from the audit log.

Against a 25,000-contact synthetic estate with deliberately conflicting edits on both sides, the mapping registry resolved every conflict to the declared owner with zero silent overwrites, and a full reconciliation sweep completed in under four minutes. Median propagation from CRM edit to database visibility measured 3.1 seconds.
