# Data management - Docs

> Looking to get third-party data in or out of PostHog? Check out the [data pipelines docs](/docs/cdp.md).

PostHog has many tools to manage all your data.

These tools can be found in the [data management](https://us.posthog.com/data-management/events) and [people and groups](https://us.posthog.com/persons) tabs.

## Events

The [Events tab](https://app.posthog.com/data-management/events) contains a list of all the different events captured into your PostHog instance. They are sortable by name, last seen, and type (custom vs default).

Each event also contains the top custom properties for that event including their type, tags, and an example.

### Event details

Clicking on an event from this list shows more details about it, such as:

-   An editable description
-   The raw event name
-   First and last seen dates
-   Top custom properties
-   Matching events

Clicking the **Edit** button in the top right enables you to edit the description, tags, and verification status. You can see and edit the description, tags, and verification status wherever you use this in PostHog, such as insights.

This is useful for keeping track of what data is up-to-date and relevant.

## Actions

The [actions tab](https://app.posthog.com/data-management/actions) contains a list of all created [actions](/docs/data/actions.md). They are sortable by name, who created them, creation date, and whether they post to a [webhook](/docs/webhooks.md).

The list also contains the action type, description, and tags. Clicking on an action takes you to that action's details page where you can edit it.

## Properties

The [properties tab](https://app.posthog.com/data-management/properties) contains a list of event, person, and group properties that have been captured into your PostHog instance. They are sortable by name and each listing also contains their type and tags.

## Annotations

The [annotations tab](https://app.posthog.com/data-management/annotations) enables you to create and edit [annotations](/docs/data/annotations.md). These enable you to add written notes to specific dates and times that show insights and dashboards.

You can also sort by date and time, scope (project), creator, and creation date.

## History

The [history tab](https://app.posthog.com/data-management/history) contains a log of all the changes to events description, property descriptions, tags, verifications, and deletions.

## Ingestion warnings

Sometimes PostHog runs into problems during ingestion due to incorrect or suboptimal usage of PostHog. For example, if you capture an event with a generic ID like `null`, PostHog doesn't ingest it.

If this happens, we do our best to still ingest the event and we log an ingestion warning.

See [ingestion warnings docs](/docs/data/ingestion-warnings.md) for a complete list.
