> Get started with the ABBYY FlexiCapture Cloud REST API: check prerequisites, activate your Developer's License, and adapt a sample project for integration.

ABBYY FlexiCapture Cloud REST API is a simple and easy-to-use application programming interface for integrating document capture functionality into third-party ERP, CRM, RPA, and other systems.

From this section, you will learn how to start working with the ABBYY FlexiCapture Cloud REST API and adapt the sample project for use with it (including some export features specific to the REST API).

<Note>
  To configure layouts, captured fields, and other processing options, a custom FlexiCapture project is required (see [Creating a project](/flexi-capture/project-settings/projects-project-settings)).
