This is a partial update — send only the fields you want to change. platform_updated_at (the timestamp of the change on your platform, in milliseconds since the Unix epoch) is required on every request.

💡 Use the Examples / schema dropdown on the request body to see common update scenarios (standard details, change of address, change of name, W-9 document generation, W-9 document upload, W-8BEN, tax withholding, KYC/compliance, EDD, and an all-accepted-fields reference).
