### Who can use Pulse?

All users who have access to a project in Uniform can open Pulse in that project. Pulse uses your Uniform sign-in, so you do not need a different account or password.

### Which projects have Pulse?

Pulse shows only in the projects where Uniform activated it. To add Pulse to more projects, [request activation](https://docs.uniform.app/docs/apps/request-activation) or speak to your Uniform account representative.

### Can I see events from before Pulse was activated?

No. Pulse starts to record events when Uniform activates it for a project.

### How long does Pulse keep events?

Pulse keeps events for 90 days. In Pulse, you can look back a maximum of 14 days at a time.

### How fast do new events show?

Uniform usually sends each event to Pulse a few seconds after it happens. An open Pulse tab checks for new events every 10 seconds. For more information, see [live updates](https://docs.uniform.app/docs/apps/uniform-pulse/activity#live-updates).

### Does Pulse show what changed in a field?

No. Pulse shows who changed which item, when, and through which source. To see all the data that Uniform sent for an event, open the event and select **Raw webhook payload**.

### Why does an event show "API key" instead of a person?

An API key, a personal access token, or an automation made the change. Examples of automations are import scripts and AI agents. To find the API key, look at the **Actor** column. It shows the name of the key, or its ID if Uniform did not send a name.

Give each script or integration its own API key. Then you can see which one made each change.

### Why does an event show "System"?

Uniform made the change itself, not a person or an API key. An example is a scheduled release launch.

### Which time zone does Pulse use?

Pulse uses the time zone of your browser.

### Is our data shared with other customers?

No. Pulse keeps the data of each customer in a separate database.

### Pulse says "This project is not connected to Uniform Pulse"

Uniform did not activate Pulse for this project. To activate it, [request activation](https://docs.uniform.app/docs/apps/request-activation) or speak to your Uniform account representative.

### Pulse says "You do not have access to this project"

Your Uniform user does not have access to this project. Ask a team admin to give you access to the project.
