Adds a key/value pair to an extraction, where the value is a constant that's not necessarily present in the PDF. This lets you include information, such as vendor or form names, that may be lacking from the PDF. For example, imagine a vendor solely issues 6-month policy quotes, so they never state the policy duration in the PDF. Use the Constant method to add policy_duration_months: 6.

Parameters

The following parameters are in the computed field's global Method parameter:

keyvaluedescription
id (required)constant
value (required)stringThe value to return in the field's key/value pair output

Examples

The following example shows adding a form name and policy duration as constants to a config's output.
