Use the Discovery APIs

Make a GET request to the project route (no ID is required) using the Discovery Service for retrieving information about the newly created project. The URL needs the org/tenant and the /du_/dpi/framework/projects path. Once you receive the response, every other call that follows requires a some information (projectID, classifierID, extractionID, etc) that are available in the responses of the Discovery calls.

Get the project information

Retrieves all available projects from Document UnderstandingTM.
curl -X 'GET' \
  'https://{fqdn}/uipathstgss/UiPathDefault/du_/api/framework/projects?api-version=1' \
  -H 'accept: text/plain' \
  -H 'Authorization: Bearer eyJhbGciOiJSUzI1NiIs***Q'curl -X 'GET' \
  'https://{fqdn}/uipathstgss/UiPathDefault/du_/api/framework/projects?api-version=1' \
  -H 'accept: text/plain' \
  -H 'Authorization: Bearer eyJhbGciOiJSUzI1NiIs***Q'

Response of retrieving the project information

Provides details about the used predefined project.
