A client can choose to add a complete contractor record directly. Note that this operation will designate the worker as a 1099-issued contractor without a formal employment relationship.
The client must capture all required data to submit a complete worker record. This option is only appropriate if the integrating application assumes the risk and responsibility of capturing potentially sensitive personally-identifiable data about the worker.
Verifying the contractor's TIN
Provide the contractor's Form W-9 information in w9FormResponse so we can verify their taxpayer identification number (TIN) with the IRS. Either socialSecurityNumber or employerIdentificationNumber is required, depending on the contractor's taxClassification. You can check the result of this verification later via the tinVerificationStatus field on the worker's profile.
