Hey Hey!

I have a question while building flows that can we make the flow to work only if certain conditions are met?

To be clear, i have this flow.

 ![image](https://us1.discourse-cdn.com/flex020/uploads/parabola/original/1X/f50260e8c36fe4d15e5b8802100caf3796009890.png)

Parabola catches a hook and expands the JSON. While at here, i want to break it into row and filter only 2 values, namely id and member id. Now i want to proceed further only memberid has a value.

I though if/else would do the job and added to the flow but still figuring out how can i do it.

This is what i have inside if/else👇

I want to stop this flow here and not send it to Webflow if memberid is blank(here i set it as _false_)

I’m not ssure if this is the right approach to gate the flow. Can anyone help me figure out this?

Thanks in advance 🙏
