Hello all,  
does somebody know how to end a split test via the api?  
I couldn’t find something in the documentation and it is not that obvious to me to only edit the email via patch. But I guess it is actually possible to end the Split testing and simply overwrite some data.

Who knows what? Would be a big help. I will make a video how to use that afterwards…

The general idea is to send an email to a specified number of leads picked randomly and perform a split test for 2 hours. Then pick the winner and send the email to the rest of the segment.

Cheers,  
Alex

Hello Alex!  
Very useful topic.  
I just quickly looked at the reference, and saw A/B testing related info there:

Have you looked into that? Are you asking the actual API calls, or if it’s possible at all?

Joey

Hi Joey,  
late but solved. I made a really creepy Frankenstein 🙂

two hours after sending the email to my test-segment i send a webhook to n8n with the email\_id.  
With n8n I change the percentage for the variants and delivery directly in the variantSettings in the database.  
It works. Only pitty is: I need to start the campaign with two segments: One for the splittest and one which gets the mail after the test is “over”.

For now it is ok. Maybe I’ll give it another go.
