Each workflow will start from the beginning. Unlike resume, which continues from where workflows failed, restart executes the entire workflows from the first step. New workflow run IDs are generated and all steps will be executed again. A maximum of 50 workflow runs can be restarted per request. If more runs are available, a cursor is returned, which can be used in subsequent requests to continue the operation. When no cursor is returned, all entries have been processed. Each restarted workflow run is assigned a new random Run ID. ## OpenAPI ````yaml /workflow/openapi.yaml post /v2/workflows/dlq/restart openapi: 3.1.0 info: title: Upstash Workflow REST API description: > Upstash Workflow is a serverless workflow orchestration service built on top of Upstash QStash and Upstash Redis. version: 2.0.0 contact: name: Upstash url: https://upstash.com servers: - url: https://qstash.upstash.io security: - bearerAuth: [] - bearerAuthQuery: [] paths: /v2/workflows/dlq/restart: post: tags: - DLQ summary: Bulk Restart Workflows from DLQ description: > Restart multiple failed workflow runs from the DLQ.
