## What you can build

Use API v2 to:

* Manage email accounts, campaigns, leads, and lists.
* Connect Google and Microsoft email accounts through OAuth.
* Receive real-time activity through webhooks.
* Manage sub workspaces from an admin workspace.

## Before you start

You need access to an Instantly workspace and an API v2 key. When you create a key, select only the scopes your integration requires.

Follow the [quickstart](/quickstart) to send your first request.

## Base URL

Send API v2 requests to:

```text theme={null}
https://api.instantly.ai/api/v2
```

Authenticate each request with your API key as a bearer token. See [Authorization](/getting-started/authorization) for details.

<Warning>
  Keep your API key secure. Never expose it in client-side code or commit it to source control.
</Warning>
