Can I start the timer in the Google App Engine?

Question

For example, check status every 30 seconds or periodically poll a web service?

Answer 1

App Engine The Cron service allows you to configure regularly scheduled tasks that run at specific times or at regular intervals

A cron.yamlfile in the root directory of your application (next to app.yaml) configures scheduled tasks for your Python application.
For instance:

- description: Webservice polling
  url: /tasks/pollawebservice
  schedule: every 30 minutes

The field urlcontains the URL of the application that will be called by the Cron service.
