A/B testing for customers who want to try different application flows.

### Through Jobylon

You can pass the name of the A/B test as a query parameter on the Jobylon URL. The query parameter should be called `jbl_ab_test`. We will store it in the browser session storage for 30 minutes or until the session expires, whichever is shorter. In other words, it will be stored for a maximum of 30 minutes. If a new A/B testing query parameter is found on the URL, the existing one will be overridden and the timeout will be reset to 30 minutes. As long as the user ends up on the application form within 30 minutes, the A/B testing query parameter value will be stored with the application. A `ab_test` parameter is added to the application data sent to your [webhook](#).

### Through the Push API

Just add the `ab_test` parameter when pushing to Jobylon and the data will be stored in Jobylon.

Please ensure that the `ab_test` parameter is less than `100 characters`
