Generating a Form W-9

To create a Form W-9 directly from our API you'll need information about the Payee, form fields values, and optionally information about the Payer.

📘
tin or tinFingerprint ?
For both the Payer and Payee we allow you to pass either the plain text tin or a previously created tinFingerprint.

curl \
  --request POST \
  --url https://sandbox-api.withabound.com/v4/documents/w-9 \
  --header 'accept: application/json' \
  --header 'content-type: application/json' \

📘
Automatic Tin Verification
It's important to note that if the combination of the Payee's or Payer's name and tin has not been seen before on the Abound platform, a Tin Verification will automatically be created. In the event that a new Tin Verification was created, a tinVerificationId will be returned in the response nested in the payee and/or the payer object(s).
