Change partition for A/B test

A partition set allows your organization to divide end-users who visit a property into one or more distinct partitions (groupings) who can receive different messaging scenarios. While testing your web property, you can force the assignment of a particular partition for your visit to test the messaging experience.

Sourcepoint uses a randomly generated number between 0-999 which correlates to the percentage configured for each partition within the set. See example below for more details: 


Your organization has configured an A/B test for two messaging scenarios and want half of the end-users visiting your property to receive scenario A and the other half to receive scenario B.


In descending order, Sourcepoint will assign the numbers between 0-999 to each partition based on the percentage configured for that partition. In our example, 50% of the numbers will be assigned to A group and 50% of the numbers will be assigned to B group.

Partition Name Percentage Configured Numbers Assigned
A group 50% 0-499
B group 50% 500-999

To change the partition set, load your web property but do not interact with the message. Add the following query string parameter to the web property URL

Parameter Required Value
_sp_change_partition true A number that corresponds to the partition you wish to view between 0-999.
//Example URL

  Note: You will need to load the web property first without the query string parameter and then append the web property URL with the query string parameter after your message has loaded.  

Reload the page when finished. The partition that corresponds to the value of your query string parameter should load on your web property.
