Which are the Finder Variables to Get all worker national identifiers?

Summary:

Using the NationalIdentifierNumber as a parameter in a GET request, what is the finderName that we need to use in order to get all the information about the worker?

And what is the variableName?

We have the following documentation that seems to be incomplete:

Format: ?finder=<finderName>;<variableName>=<variableValue>,<variableName2>=<variableValue2>

The following are the available finder names and corresponding finder variables:

• PrimaryKey: Finds all the worker national identifiers that match the specified primary key criteria.
• Finder Variables:
  • NationalIdentifierId; integer; Surrogate identifier for the worker's national identifier.
• findPrimaryNID: Finds the primary national identifier of a worker based on the specified criteria.
