Upload one or more attestations for an associated person. Re-uploading a type replaces the previous value. Business-level attestations belong on the compliance review endpoint.

Residential address, identity document, proof of address, and proof of signatory authority are checked automatically and return a pending validation status until the check finishes; a residential address may be replaced with its standardized form. A review cannot be submitted while a check is pending, or failed with a BLOCKING failure. Re-upload to resolve a failure, or acknowledge WARNING-only failures when submitting.
