Is it possible to create custom triggers?

Is it possible to create custom trigger parameters for a manual trigger? 

I'm trying to create a flow that is triggered manually with a drop-down list of custom parameters. I want a list of all the clients so that the user can either select a client name from the existing list or write in a new one. The flow is going to create a folder structure underneath the client folder.

 

I could have the user type in the client name, and then have the flow check the folders to see if that client exist, or if another folder needs to be created with that client's name. However, I want to eliminate the possibility of misspelling the client name by using a pre-existing list.

 

I see that you can create a dropdown list of items for the manual trigger flow, but is there any way of keeping it updated? Can I allow the user to add another item to the drop-down list?

    Hi @EthanSummerhays 

     

    Yes, but you have to create a custom connector. You cannot extend an existing connector that you do not own.

     

    Extend apps with Power Automate - Power Automate | Microsoft Learn

    And in things like logic Apps etc use WebHooks.

    @FLMike what if I just want a list of clients to show up from SharePoint? Does that require the same custom connector process? We already have all of our client names in SharePoint.

    Unfortunately there is no Dynamic way to create an updatable "list" and event with a custom connector I don't believe you can do this.

     

    What is the UI that sits in front of the Flow? You could very easily create a Canvas App, that sits in front. Then use a SharePoint list to store rows of (text) names that people list.

     

    in the same app, but a text input that lets they type in their name if they don't see it.

     

    Then in your trigger, add a Text input and pass that in. Then have the Flow check if that exists and do what you said. Also, you could have a history where you track which ones have been done, so the flow just queries that list to see if it needs to happen etc.

     

    sorry for the confusion. Above is how I would do what you are asking, but no for the Flows themselves, you cannot have an updatable list of dynamic inputs.
