Send to OCR

The Send to OCR block is used to send a PDF document to OCR for reading. The block allows the recognition of text from a PDF by preparing and sending the file to a web service.
Double-clicking the block does not open the form, because the block settings cannot be changed. The block reads data from the predefined variables.

For the block to work properly, the variables for logging in to the web service need to be defined beforehand:
- OCRUserName – Username for logging in to the OCR service.
- OCRPassword – Password for logging in to the OCR service.
- OCRAPIKey – API key of the OCR service provider.
The result from the web service returns to the user the information contained in the following variables: OCReSlog, OCRFullLineItems, OCRHumanCheck, OCRAddCandidates, OCRAddLineItemCandidates.
