Handling Server-Side Experiment Responses

The Choose API returns the chosen experiment or personalization result for a given user.

⚠️ Important:
Intempt only provides the experiment decision.
Your backend must interpret and apply the result.

Applying Variations in Your Backend

Examples:

If the variation contains a modified headline:

Replace the headline before rendering the page.

If the variation body includes values such as:

"buttonColor": "#FF0000"

"heroLayout": "variantB"

Your server applies these configurations before sending the response.

If the payload includes product recommendations:

"products": [
  { "title": "...", "price": "...", "category": "..." }
]

Insert them directly into:

A server-rendered HTML block

An API response

A mobile app view

Use the Choose API to fetch experiment or personalization results.

Identify users via sourceId + profileId or userId.

Request variations by names or groups.

Apply the returned values in your backend — Intempt does not modify your UI automatically.
