4 Events

Artifact Version Created Emitted when a new version of an artifact is logged to a project. Maps to W&B automation event `CREATE_ARTIFACT`. Fires once per `wandb.log_artifact` (or the connector's `create_artifact` action) that produces a fresh version.
Artifact Alias Added Emitted when an alias is applied to an artifact version. Maps to W&B automation event `ADD_ARTIFACT_ALIAS`. Fires when the connector's `update_artifact` action adds one or more aliases (via the additive `addAliases` mutation), or when a user assigns an alias via the W&B SDK / UI. Filterable by regex on `alias` at the automation level.
Artifact Tag Added Emitted when a tag is applied to an artifact version. Maps to W&B automation event `ADD_ARTIFACT_TAG`. Fires when the connector's `update_artifact` action supplies additional tag entries, or when a user tags a version via the W&B SDK / UI. Filterable by regex on `tag` at the automation level.
Run State Change Emitted when a W&B run transitions to a new state (Running / Finished / Failed). Maps to W&B automation event `RUN_STATE`. Fires whenever the connector's `update_run` action supplies a `state` input (using the `updateRunState` mutation) and whenever the W&B SDK reports state transitions during job execution. Available on Multi-tenant and Dedicated Cloud deployments only. Payload note: W&B's RUN_STATE automation template only substitutes `run_name` (the run's display name) — no `run_id`, `run_state`, or `run_url` variable is provided. To fetch full run details, use `get_run` with (entity_name, project_name, run_name).
