Invoke Azure Function task

Azure Pipelines | Azure DevOps Server 2019 | TFS 2018 | TFS 2017

Use this task in a build or release pipeline to invoke a HTTP triggered function in an Azure function app and parse the response.


In Microsoft Team Foundation Server (TFS) 2018 and previous versions, build and release pipelines are called definitions, service connections are called service endpoints, stages are called environments, and jobs are called phases.


Can be used in only an agentless job of a release pipeline.

Where should a task signal completion when Callback is chosen as the completion event?

To signal completion, the Azure function should POST completion data to the following pipelines REST endpoint.


**Request Body**
{ "name": "TaskCompleted", "taskId": "taskInstanceId", "jobId": "jobId", "result": "succeeded" }

See this simple cmdline application for specifics. In addition, a C# helper library is available to enable live logging and managing task status for agentless tasks. Learn more
