Set trigger condition programmatically

Posted on by BV-14081439-0

In our custom connector, we would like to set the trigger condition based on the value of a dropdown in the trigger.

Example: We have a trigger that triggers when any form has been submitted. Now we would like to add a dropdown to select a form in the trigger, which should set the trigger condition such that the flow only triggers when that specific form has been filled in

According to support, this should be documented in detail: "Yes, it is possible to set the trigger condition programmatically based on a dropdown in Power Automate. You can find detailed guidance and support on this topic in the Power Automate documentation and community forums.".

Can anyone point us to the right place?

Hello there,

so you basically want to have a "dropdown" to change your trigger condition ?

There is nothing like a dropdown you can configure for that specially because i guess your flow is an automatic flow, for manual flows you can do that kind of stuff.

in this case a workaround to do achieve a similar outcome is using environment variables inside your trigger condition, lets say that you want to check if a column value is the same as your envionment variable, your code should look something like this:

@equals(triggerOutputs()?['body/columnname'], parameters('Triggercondition (emh_Triggercondition)'))

then you can change value of the environment variable directly from the variable definition table, with a small power apps or even another cloudflow by email teams.

HI,

The real issue, is if the data incoming has the ability to be read at that time.

Sure you can create an Input. What I believe you want it.

I'm going to Select a form (with ID 1234568) That's in your trigger

Then I want to compare that to a Value in the Payload coming into the trigger, which is different than the parameters.

so something like essentially like

equals(@triggerBody()?['MyFormSelectionValueWhichMayNeedAPathIDontKnowItsYourParameterData'], triggerBody()?['WhateverObject/DataComingInAndNeedsPathToTheFormValue'])
