Retrieve data from employee and employer documents via Finch’s Documents APIs. Now in Beta and supported for W-4 files.
/employer/documents
API provides the list of documents available in the HR or payroll system for an individual employee or all employees and specific document types.
Currently, only W-4 document types are supported, but the API is built to scale out to additional document types.
/employer/documents/{document ID}
API endpoint provides detailed information about individual documents based on the list of documents returned by the /employer/documents API above. For W-4 forms, you can gain access to filing status, dependent withholding and additional withholding details.
