Enter flow according to a/b test

Hi @power pops, welcome to the community!

Yes, you can “switch” between different Flows by adding a Flow Filter as a condition based on the $source value of Sign Up Form.  Make sure you have a different $source value for your version A vs version B for your submit button.

See here:

Then in your Flow Filter you can set the Flow Filter as:

So here, when someone signs up for my “A” version of the Signup Form, the $source value will be set to “A” (or whatever you want to label it), and then here in my Flow Filter, I’m only allow subscribers with “A” as their $source value to enter the Flow.

Repeat this for “B” (and any other variants down the line) and you can have distinct Flows for each A/B Test Variant.

I’d also like to recommend, that another way to approach this is to use a “Conditional Split” if you want to just change a few messages (typically only the first message needs to change) but then no matter which variant they signed up for, they go down the rest of the Flow the same after the first message.

Here, I’m using a Conditional Split between A or B and any other subscriber without A or B to go through one Flow like this:

Hope this helps!
