# Activity history

> Use activity timelines to understand what happened on a customer, opportunity, or workflow.

Activity timelines show historical events on records such as contacts and opportunities. Use them to understand what changed, who changed it, and what happened next.

## Activity timeline uses

* Review communication history.
* See when records were created or updated.
* Understand how tasks, meetings, conversations, and opportunities relate.
* Audit recent changes before replying to a customer.

## Where activity appears

## Reading activity

When reviewing activity, look for:

* Most recent customer touch.
* Open tasks.
* Completed or missed appointments.
* Hand-off events.
* AI suggestions or decisions.
* Changes to owner, status, stage, or key properties.
