# Save and calculate VAT figures (/reference/oauth-update-vat-draft)

Replace all reported figures using decimal strings and the latest revision. Stale revisions return 412. Submitted filings and processed invoices cannot be edited; an unprocessed invoice is voided before recalculation. A successful write returns a new revision. After a timeout, read the filing before retrying.

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.
