If you have a license for ABBY Cloud OCR you need to first register your application on their website. ABBYY Cloud OCR SDK service requires authentication before allowing access to its API. To have your client program authenticated with the service, you need a registered Application ID and Application Password. You can find the Application ID and Application Password in the e-mail message sent to you on application creation. To get started and create an application, please follow this to register.
Please note that abby finereader engine(the Abbyy OCR activity) and abby cloud(the Abbyy OCR cloud activity) are different.
Hope this helps.
