      Overview

      Create a workflow

      API Explorer (recommended)
      Click to debug
      Tencent Cloud API Explorer makes it easy for you to make online API calls, verify signatures, generate SDK code, and search for APIs. You can use it to query the request and response of each API call and generate sample SDK codes for the call.

      Request

      Sample request

      POST /workflow HTTP/1.1
Host: <BucketName-APPID>.ci.<Region>.myqcloud.com
