https://api.wingspan.app/v3/compliance/forms//verify-identity

Recipient-side identity check. The recipient submits the last four digits of the TIN on the form to prove ownership; on success they are granted read access to the artifact. This is not an IRS TIN-match verification.

required

Unique identifier of the form

string

Last four digits of the SSN/TIN on the form, to prove ownership.

Headers
string
length between 1 and 255
^[\x21-\x7e]{1,255}$

Optional idempotency token for authenticated POST and PATCH requests. Reusing the same key and body returns the cached response for 24 hours, except credential operations that explicitly document a 409 because one-time secret material is never cached; reusing it with a different body returns 409 IdempotencyKeyConflict. Use 1-255 printable ASCII characters.
