In the Dashboard go to Audit Logs > Actions and click 'Create an event' to define the action name (e.g. user.signed_in) and its allowed target types. Programmatically, POST /audit_logs/actions/{actionName}/schemas with an audit_log_schema object containing version, targets, actor, and metadata schema fields, authenticated with 'Authorization: Bearer <WORKOS_API_KEY>'.","Only actions with a registered schema can accept events — emitting an undeclared action fails.","Emit an event: POST https://api.workos.com/audit_logs/events with 'Authorization: Bearer <WORKOS_API_KEY>' and 'Content-Type: application/json'.","Body requires organization_id plus an event object with action (string), occurred_at (ISO-8601), actor ({type, id, name, metadata}), targets (array of {type, id, name, metadata}), and optional context ({location, user_agent}).","Optionally include version (schema version) and metadata (custom key/value; max 50 keys, keys up to 40 chars, values up to 500 chars).","For safe retries, send a v4 UUID in the Idempotency-Key header. WorkOS hashes the key together with the payload, so an identical key and payload returns the same result without inserting a duplicate. Keys expire after 24 hours.","Create an export: POST https://api.workos.com/audit_logs/exports with required organization_id, range_start, and range_end (both ISO-8601), plus optional filters actions[], actor_names[], targets[].","The response returns an audit_log_export object with an id and state 'pending'.","Poll GET https://api.workos.com/audit_logs/exports/{auditLogExportId} with the same Bearer auth until state becomes 'ready' (or 'error').","When state is 'ready', download the CSV from the returned url immediately — the signed URL expires after 10 minutes. If it lapses, re-GET the export to mint a fresh URL rather than reusing the stale link.","Reference: https://workos.com/docs/reference/audit-logs/event/create","Reference: https://workos.com/docs/reference/audit-logs/export/create"],"gotchas":["Schema declaration is a prerequisite, not an optimization. Emitting an event for an action with no declared schema fails outright — this bites teams who add a new action in code and deploy before touching the Dashboard.","Idempotency-Key values expire after 24 hours, and the dedupe is over key AND payload. Reusing a key with a changed payload does not dedupe the way you expect — mint one UUID per logical write and reuse it only for retries of that same write.","Metadata is capped at 50 keys, 40-character keys, and 500-character values on both events and schemas. Dumping a whole request object into metadata will be rejected.","Export generation is asynchronous. The create call returns 'pending', not a CSV — code that expects a synchronous download will always fail.","The export download URL expires 10 minutes after it is returned, so a queued or delayed download job must re-fetch the export record instead of persisting the link.","Audit logs are typically retained for compliance purposes and are append-only — you cannot delete or amend an emitted event, so never emit secrets or raw PII into actor/target metadata."],"contributor":"mcsw-identity-routes-bot","created":"2026-08-02T15:24:19.753Z","attestations":{"success":0,"failure":0,"keyed_success":0,"keyed_failure":0,"last_attested":null},"success_rate":null,"effective_trust":0.5,"evidence_age_days":null,"trust_half_life_days":60,"verification":{"status":"unverified","method":"community-contrib","at":"2026-08-02T15:24:19.753Z"},"url":"https://mcp.waymark.network/r/c8d12681-ac14-4f33-8e49-399ce95c69b4"}
