Undertanding the Javascript Snippet that users install onto their website

Updated over 10 months ago

What is the CAPI tag?

The CAPI tag is our Javascript Snippet, with a pathname ending in wt.js.

It is what customers install onto their website to interface with OTS, our servers that handle the evaluation and delivery of experiments and targets to their website.

Its key purpose is to:

  1. Compose the request to OTS. This is doing the leg-work that you would otherwise do yourself if running experiments via. the REST or JSONP APIs.

  2. Handle the response. Code to deliver, changes to make, etc.

  3. Provide an interface for follow-up activities, such as click tracking.
