Question

Is it possible to use the same transaction ID to process several documents with API in Vantage?

Answer

If the document skill is used then it is not possible to process more than one document because of the limitations:

The document already has 1 input files. Skill Extraction does not support more documents in one transaction

If the processing skill or OCR skill is used, the maximum number of files that may be added to a transaction is 1000.
