Set up a webhook for a Full Stack project datafile

  • Optimizely X Full Stack

  • Ensure that you know when your datafile has been updated
  • Ensure that you know when your experiment has been changed
  • Set up a webhook

How do you make sure your Optimizely X Full Stack server application has the most up-to-date version of the datafile? Set up a webhook to receive an update every time the datafile changes.

A webhook is an HTTP callback that notifies your server application when the datafile is updated. Register a URL that Optimizely will notify anytime the datafile changes.
