use the output of one flow in another flow

[kmanakonda]

Hi,

I have two power auotmate flows A and B. The output of a compose action in flow A is a link which changes and I want to use that link in Flow B inside a send email action and every time the link changes in flow A it should be updated in flow B as well automatically. How do I achieve this?

It sounds like you need to make Flow B a Child Flow. Flow A could trigger Flow B after the compose action if Flow B is set up as a child flow.

This article details how to create a Child Flow and trigger it from a parent flow - https://learn.microsoft.com/en-us/power-automate/create-child-flows

Thank for the response, but the suggested solution wont work i guess as the flow that i a wanted to use as child flow has a "Recurrence" trigger.

If you want it that way you should store the information somewhere and get it in flow B. I think right now also environment variables can be used for that but where you want to store the information is up to you.

Hi @Matthy79 

I have tried to use environment variables but the problem is I dont see a way to dynamically store the output of flow A into a environment variable.

I am not on the computer but I found this:

I am sure you could skip some parts, but you have to know that environment variables are also stored in Dataverse.

I had trouble working with the Dataverse's environmental variables, so my solution here was to create my own "Environmental Variables" storage using a SharePoint List with several generic text/numeric value storage columns:

When a flow completes, it can get/post/put/delete information as-needed.

Hope that helps!
