Add and edit JavaScript in the experiment variation

Requirements

access token

The Automation API requires an access token. Retrieve the token programmatically by following the instructions in the obtaining an access token section.

Goal

Update the variation (Variation 1) of the created experiment with:

Kameleoon.API.Core.runWhenElementPresent("#bloc-567, .cta-button, #bloc-789", function(elements) {
  document.querySelector(".cta-button, #bloc-789").innerText = "More new text";
});

Then change the text to “Updated Text”. See the API reference for code details. The update uses the Partial Update Variation endpoint.

variationId and experimentId

Find the IDs by selecting Experiment_1 in the dashboard:

PATCH https://api.kameleoon.com/variations/{variationId}

Name	Type	Description
