# Pay a Certificate of Good Standing request with a voucher (/reference/post-legal-entities-id-certificate-requests-request-id-pay-voucher)

Applies the voucher to the request invoice. Issuance runs asynchronously after payment. Poll until `statusId` is `Issued`, `Rejected`, or `Cancelled`, then stop. A certificate `documentUrl` is available only for `Issued`; rejected or cancelled requests must not trigger automatic repayment. Standard keys act on every entity the key owner actively represents. Agent Keys are limited to entities incorporated through the API and need active representation and the listed `agent:entity.filing.*` scope. Agent writes also require an active Manifestation of Will. OAuth tokens and Partner Keys cannot call these filing endpoints. See https://docs.eprospera.com/entity-filings for signing, payment, and recovery. Agent scope: `agent:entity.filing.pay`.

Account deactivation revokes personal API keys, including Agent Keys, and OAuth authorizations. Account reactivation requires new API keys, including new Agent Keys, and consent; previously issued credentials remain invalid.
