Revoke a user's verification with a specific merchant. After revocation, the user must reauthenticate and complete MFA before accessing their user details or transacting with that merchant again. Identify the user by their AeroPass userId (UUID). The specified merchantId must be within the authenticated token's merchant scope, and the user must have an existing association with that merchant.

Revocation preserves the user's Aeropay account, linked bank connections, transaction history, and verification with other merchants.

To restore access, call POST /v2/user again to initiate authentication, then complete MFA through POST /v2/confirmUser. Once confirmed, GET /v2/user becomes available again. A previously stored userId does not bypass this requirement: GET /v2/user will not return the user's details for that merchant until verification is restored.
