# Create or resume a quarterly VAT draft (/reference/oauth-create-vat-draft)

Use personal for the caller or a consented legal-entity UUID. Taxpayer+quarter is the retry key: returns an existing original draft without replacing figures. Already-filed quarters, multiple drafts, and BTC/amendment drafts return 409. USD originals only. A registered RPN and eligible quarter are required.

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.
