### Overview

Execute the given workflow. This API requires a [registered application key](https://docs.datadoghq.com/api/latest/action-connection.md#register-a-new-app-key). Alternatively, you can configure these permissions [in the UI](https://docs.datadoghq.com/account_management/api-app-keys.md#actions-api-access). This endpoint requires the `workflows_run` permission.

OAuth apps require the `workflows_run` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#workflow-automation) to access this endpoint.
