How to Sync CRM Events and Timelines Across Salesforce, HubSpot, and 30+ Platforms with a Unified API
October 31, 2025
Customer activity data lives across dozens of systems — emails, enrichment tools, automations, and meetings — yet the CRM remains the single source of truth for relationships and revenue. The challenge? Every CRM structures events differently, and maintaining per-vendor integrations for activity tracking quickly becomes unmanageable.
Unified.to simplifies this by providing a single API to record, read, and analyze CRM timeline events. You can log outbound emails, enrichment runs, app automations, or third-party triggers — and pull historical activities for analytics, attribution, and deal scoring.
When to Use Unified for Event Sync
With a unified API, you can:
- Create audit trails for outbound messages, enrichment actions, and automations.
- Centralize activity into CRM timelines for Contacts, Companies, and Deals.
- Pull events for insights, attribution, or pipeline health scoring.
- Standardize event ingestion across Salesforce, HubSpot, Pipedrive, and 30+ other CRMs.
Unified Objects & Key Entities
Unified.to normalizes event and activity data so it's consistent across every CRM platform:
| Object | Purpose | Notes |
|---|---|---|
| Event | Timeline activity (note, meeting, email, call, task, automation) | Use standardized event types and link them to related records. |
| Contact | Person the event concerns | Associate via contact ID or email. |
| Company | Account the event concerns | Associate via account ID or domain. |
| Deal | Opportunity connected to the event | Attribute influence for scoring or forecasting. |
| Lead (optional) | Pre-qualified prospect | Log top-funnel activity before conversion. |
This unified schema ensures event logging and retrieval behave identically across every connected CRM.
Example Event Scenarios
| Scenario | Example Event Type | Description |
|---|---|---|
| App sent an email | email | Log subject, sender, and recipient context; associate to Contact and Deal. |
| Contact enriched | note | Record enrichment summary, provider, and confidence score. |
| Third-party trigger | note / task | Log automation outcome or workflow run; include correlation ID. |
| Meeting booked | meeting | Record scheduling outcome and follow-up task. |
| Call completed | call | Capture call disposition and transcript or recording link. |
Data Flow for CRM Event Sync
