Child Flow with more than 20 inputs

Hello, 

 

I have a parent flow that triggers when a Form is submitted, and need to pass more than 20 inputs to the child flow.  I know there is a limit on the number of inputs when you manually trigger a flow (child flow), but wondering if there is any way to get around this.  I tried to have the input be the response ID from the Form, but it can't be used by the Child Flow unless the trigger is "When a new response is submitted".  

 

Thanks in advance for the help.

In your trigger condition, add a text field that is required when calling the child flow so you can populate it from the flow calling the child flow. You can then use the expression builder to access the value with the expression:

 

triggerBody()['text']

 

Note, if you have more than one text field in the trigger, you'll need to check to make sure you are referencing the correct one. They should be named text, text_1, text_2, etc. When you first save the flow, it will look like this:

But once you save it and edit again, it will show the field as you named it in the trigger:

I think this is what you are asking to do.

Can you show a screenshot of your flow?

 

I don't understand why you can't add the action "Get Response Details" to the child flow?

I just opened up a child flow in a solution and added this action "Get response details" without there being any other type of form trigger or action.

You are unable to use that step?

Hi @kjwolf326 

 

Pass the JSON object to your child flow as a single input type text. Here are the steps:

 

This is my main flow. Here I am passing JSON object which I want to process in my child flow.

This is my child flow. Using the Details input (JSON) I have created a Parse JSON step. See the second action step called 'Parse JSON'

Above I am passing Details as JSON object. This way you can avoid too many input values to process your child flow.

Sorry I wasn't more clear.  I can add the action 'Get response details' without issue, but I can't get the child flow to get the details for the submission that kicked off the parent flow trigger.  Even trying to pass from the parent flow 'Response ID' as a child input, it doesn't let me select that as dynamic for the child.  Hope that makes more sense.

Hi @kjwolf326 

 

Why can't you use the standard trigger.

Then from here you can pass the Value collection as JSON input like I described earlier.

 

Thanks
