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 🙏

Hey @Mohammed_Zeeshan!

Let me know if I understand what you’re trying to do correctly: you want to only send rows to Webflow that have an ID in the **Validation** field, and not send if the row contains “false”?

If so, you were on the right track! Just add a “Remove rows” step after the if/else to remove all rows that contain “false” in the Validation column.

This would prevent any blank **memberid** ’s from being sent back to Webflow.

Hope that helps!

I actually want the flow to proceed forward only if the `memberid` has a value. If not stop there. So that means if at all other fields are all fine and `memberid` has no value, still it has to stop.

Hey @Mohammed_Zeeshan, thanks for clarifying. You should still be able to use the `Remove rows` step in order to: _Include all rows in_ `memberid` _if they_ `are not blank`.

That will filter out the `memberid`'s that have no value, and only proceed with the rows that have a value.
