Auditability is built into the Midaz platform. It is not a separate plugin or product you install: the platform records an append-only trail of the actions that change or govern your data, so Organizations can demonstrate integrity, support compliance, and investigate what happened. ## Why auditability matters *** An immutable record of system activity lets you: * Preserve the integrity of data across all touchpoints. * Support internal and external audits with a verifiable trail. * Increase transparency and reduce the risk of undetected fraud. * Meet the record-keeping requirements of regulatory frameworks. ## What Midaz records *** Audit data lives inside the Midaz platform, alongside the data it describes — there is no separate audit product to install. * **Audit events** capture each recorded action: what happened, who performed it (the actor), the outcome, and when, together with a request identifier that ties the event back to the originating call. * **Transaction audit logs** capture ledger activity. When audit logging is enabled, each operation in a transaction is recorded to the audit log for downstream retention and processing. ### How audit records behave * **Append-only and immutable**: audit records are only ever added, never updated or deleted, so the historical trail cannot be rewritten. * **Metadata, not secrets**: records capture the metadata of an action, not its sensitive payload. Credentials, keys, and similar secrets are never written to an audit record. ## Querying audit records *** Audit events are read through the Midaz API, scoped to an Organization. You can filter by action, actor, outcome, and time range, and page through large result sets — enough to reconstruct the sequence of actions for a period, or to investigate a specific actor or outcome.
