# API tutorial

Get started with extracting structured data from documents using the Sensible API.

If you're new to APIs in general, these tutorials are a good starting point.

Or, if you're familiar with APIs:

* see the [API quickstart](/integrations/quickstart) to get a sample API response.
* explore the Sensible Postman collection:

[Run in Postman](https://god.gw.postman.com/run-collection/16839934-45339059-3fec-4c31-a891-9a12a3e1c22b?action=collection%2Ffork\&collection-url=entityId%3D16839934-45339059-3fec-4c31-a891-9a12a3e1c22b%26entityType%3Dcollection%26workspaceId%3Ddbde09dc-b7dd-487d-a68f-20d32b008f90)

## Prerequisites

To follow these tutorials, you need:

* An [API key](https://app.sensible.so/account). Create this key after you sign up for a [Sensible account](https://app.sensible.so/register).
* [Postman](https://www.postman.com/) desktop app, or a command line with cURL installed.
* An example extraction configuration. See the following section.

**Prerequisite: Create example extraction configuration**

1. Navigate to Sensible's [open-source configuration library](https://app.sensible.so/library/) to choose an example document type. For this tutorial, select **Tax forms**.
2. Select **Clone to account** to copy example tax forms and associated configurations for extracting data from those forms to your account.
