Only supported in Sandbox. In production this endpoint returns a 404.

Generates filings and employee tax statements for a company from its approved payroll data, so that the rest of the Filings API can be exercised in Sandbox. Pass payroll_ids and employee_ids to limit generation to specific payrolls and employees, or omit both to generate data for the entire company, including employee W-2s.

The company must have completed implementation and have at least one approved payroll. See the Tax Filings: Sandbox Testing guide for the full walkthrough, including how to simulate the filing lifecycle once filings exist.

The request is accepted with a 202 and the work runs asynchronously. Depending on the amount of payroll data and the number of employees, generation can take several minutes. Repeated requests for the same company are added to the in-progress job rather than starting a second one. A company_filing webhook with the created event is sent for each filing that is generated, after which the filings are available through List filings.
