Server Default

The default Server provider is a no-op — all methods do nothing. It serves as a safe placeholder so the workflow lifecycle can call server hooks without errors when no remote server is configured.

To send execution data to a remote API, implement a custom provider that extends the Server ABC.

Lifecycle hooks

The server provider is called automatically at these points:

Event	Method
DotFlow() init	create_workflow()
workflow.start()	update_workflow()
Workflow completes	update_workflow()
task.add()	create_task()
Task finishes	update_task()

Custom implementation

To build your own server provider, extend the Server ABC:

from dotflow.abc.server import Server


class MyServer(Server):
    def create_workflow(self, workflow):
        # POST to your API
        pass

    def update_workflow(self, workflow, status=""):
        # PATCH workflow status
        pass

    def create_task(self, task):
        # POST task data
        pass

    def update_task(self, task):
        # PATCH task results
        pass

Then pass it to Config:

from dotflow import Config, DotFlow

config = Config(server=MyServer())
workflow = DotFlow(config=config)
