Overview

The Start Doc Extraction node allows you to start a document extraction run.

Activating this smart service in the process model initiates an asynchronous analysis run in Appian, and immediately returns a Doc Extraction ID. Next, the a!docExtractionStatus() function should be used to check the status of a run.

The Appian Document Extraction page walks you through how to use document extraction functionality together in a process model. See the following list for the other smart services and functions you need to use with the Start Doc Extraction Smart Service:

• a!docExtractionStatus()
• a!docExtractionResult()
• Reconcile Doc Extraction Smart Service
• Admin Console > Document Extraction

Properties

Configuration options

This section contains tab configuration details specific to this smart service. For more information about common configurations see the Process Node Properties page.

Data tab

This tab displays all the Node Inputs and Node Outputs for the Service Node. You can add additional inputs and outputs, if needed.

Node inputs

The default inputs are:

Input	Description	Data Type	Required	Multiple
Runtime Document	The document to process	Document	Yes	No
preferredVendor	Select which vendor you would like to use for document processing and analysis. Possible values: Appian or Google. Visit the Select a Document to learn more about the extraction capabilities offered with each vendor.	Text	Yes	No
processorID	Leaving this value blank will use Appian's default processor Id. If you provide a processor Id, this node will leverage Google's Document AI API v1 capabilities. processorId is not supported when Appian is selected for preferredVendor.	Text	No	No

Node outputs

Name	Data Type	Description
Doc Extraction Id	Integer	The identifier of the doc extraction run.

After starting the doc extraction run, you should use the identifier with the a!docExtractionStatus() function to check the status of the run.
