# Signal sources overview

> How Verdikt ingests eval and observability data.

Verdikt supports three ways to get signal values into a cert window:

| Method                                                   | Best for                                             | Auth                                         |
| -------------------------------------------------------- | ---------------------------------------------------- | -------------------------------------------- |
| [Integration pull](/connecting-signals/integration-pull) | Braintrust, LangSmith, BrowserStack, Sentry, Datadog | API credentials in Settings → Signal Sources |
| [API push](/connecting-signals/api-push)                 | Custom eval pipelines, partner databases             | Agent access key (`vdk_live_…`)              |
| [CSV upload](/connecting-signals/csv-upload)             | Ad-hoc imports, manual QA spreadsheets               | Workspace session or Agent key               |

All methods attach to the **open cert window** for a commit SHA. Apply the `verdikt:rc` label (or create a release with that SHA) before posting signals.
