# Introduction

Welcome to Sensible! If you have any questions, please reach out by chat or [support@sensible.so](mailto:support@sensible.so) and we'd be happy to help you out.

To get started, see the following endpoints. Or, see the [Sensible SDK quickstarts](/integrations/sdk-guides).

| Endpoints                           | Links                                                                                                                                                                                                                     | Notes                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                |

| Document extraction (asynchronous)  | <br />- [Extract doc at a Sensible URL](/api-reference/extraction/document/generate-upload-url) <br />- [Extract doc at your URL](/api-reference/extraction/document/extract-from-url)                                    | Takes a document file, such as a PDF, and returns extracted data asynchronously. Use the asynchronous endpoints in production. You have two options for asynchronously extracting from your document: <br />- extract a doc at a URL you provide<br />- upload and extract the doc at a Sensible URL. You can then call the [Retrieve extraction](/api-reference/extraction/retrieve-extractions/retrieving-results) endpoint to get the results, or specify a webhook for Sensible to push the results to as soon as they're ready. |
| Document extraction (synchronous)   | [Extract data from a document](/api-reference/extraction/document/extract-data-from-a-document)                                                                                                                           | Returns extracted document data synchronously. Use this endpoint for testing.                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
| Get Excel from PDFs                 | [Get Excel extraction](/api-reference/extraction/get-excel-from-documents/get-excel-extraction)                                                                                                                           | Get well-structured Excel files converted from PDF documents. This endpoint also supports documents formatted as images, for example, PNG or JPEG.                                                                                                                                                                                                                                                                                                                                                                                   |
| Portfolio extraction (asynchronous) | <br />- [Extract portfolio at a Sensible URL](/api-reference/extraction/portfolio/generate-upload-url-portfolio)  <br />- [Extract portfolio at your URL](/api-reference/extraction/portfolio/extract-from-url-portfolio) | Use these endpoints with multiple documents that are packaged into one PDF file (a PDF "portfolio").                                                                                                                                                                                                                                                                                                                                                                                                                                 |
