Use the Extraction Service

Extract data from the document using the same documentId and the extractorId. The extractorID is selected based on the classification result. Select a suitable extractor based on the documentTypeId returned by the classification. You can discover classifiers either by calling the Discover Classifiers routes, or by calling the Get Project By Id route. Here are more details about how to use the Discovery Service for retrieving information about the project's available classifiers and extractors.

The POST call for Extraction can be done for synchronous or asynchronous consumption.

Each action requires one POST and multiple GET calls (due to polling), meaning that if you want to validate an extraction result, then you need to do a POST and multiple GET calls.

The following examples are using a POST call for asynchronous consumption.

Depending on the operation, Document Understanding Cloud API calls use the following classes:

• Document Class for digitized documents.
• Classification Result for classification results.
