# Config API Overview

> \[!TIP]
>
> Segment's [Public API](/docs/segment/api/public-api) is available for Team and Business tier customers to use. You can use the Public API and Config APIs in parallel, but moving forward any API updates will come to the Public API exclusively. Please contact your account team or [friends@segment.com](mailto:friends@segment.com) with any questions.

The Config API lets you programmatically manage Segment workspaces, sources, destinations, and more.

With the Config API, you can:

* List all your workspace sources and destinations to see how data flows through Segment.
* Create new destinations - or delete them - with a few lines of code.
* Create new users and assign them to scoped roles.
* Configure, disable, or view sources and manage connected destinations.
* Get a complete view of all the sources and destinations available in Segment's catalog.
* Configure a Tracking Plan to see how data conforms to your expected schema.
* Query Event Delivery metrics to build custom dashboards and alerts to monitor delivery of your events to destinations.
* Filter entire events or individual fields from reaching specific destinations.

The Config API is a set of REST services under segmentapis.com:

To see all the API methods and models see the [Segment Config API Reference](https://reference.segmentapis.com/).

At this time there are no language-specific clients. However the [API Reference](https://reference.segmentapis.com/) also contains example code snippets for cURL, Go, Node, Python, and more.

## Quick start

You can call the API from the command line. First, install `curl`:

```shell
$ brew install curl
```

### Access tokens

You can use the Config API with an access token to programmatically access Segment resources that the token can access. As of February 1, 2024, new Config API tokens cannot be created in the app as Segment moves toward exclusive support for the [Public API](/docs/segment/api/public-api/). [Migrate your implementation to the Public API](https://docs.segmentapis.com/tag/Migration) to access the latest features and available endpoints.

To create a new Config API token, [contact Segment](mailto:friends@segment.com) for support. These are currently only suitable for first party, trusted applications, such as your personal local scripts and server side programs. Partners should not prompt Segment users for their username and password and save an access token as a way to delegate access. See the [Authentication](/docs/segment/api/config-api/authentication/) doc for more information.

> \[!WARNING]
>
> You can not retrieve the plain-text `token` later, so you should save it in a secret manager. If you lose the `token` you can generate a new one.

### API requests

Now that you have an access token, you can use this token to access the rest of the Config API by setting it in the `Authorization` header of your requests, for example:

```shell
$ ACCESS_TOKEN=qiTgISif4zprgBb_5j4hXfp3qhDbxrntWwwOaHgAMr8.gg9ok4Bk7sWlP67rFyXeH3ABBsXyWqNuoXbXZPv1y2g

$ curl \
  -X GET \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  https://platform.segmentapis.com/v1beta/workspaces
```

Example response:

```json
{
  "workspaces": [
    {
      "name": "workspaces/myworkspace",
      "display_name": "My Space",
      "id": "e5bdb0902b",
      "create_time": "2018-08-08T13:24:02.651Z"
    }
  ],
  "next_page_token": ""
}
```
