[QUERY] Create and update list items

[antti-liberis]

Question
Is it possible to create and update List items in a existing list? Similar to the canvas API.

I understand this would have to be a custom function, but I don't know how to create a custom function that does anything but uses the existing slack API methods, and I can't find anything Lists related in them.

Context
I have a list with work items, and I want to automate creation and progression of new items. I currently have a no-code workflow in Slack that uses a webhook trigger and does this for me. For scalability, I'm looking into building a custom slack app.

I need to be able to select the list item and update certain fields when the work progresses and new webhook triggers are hit.

Thanks in advance

Hello @antti-liberis , there are couples of APIs to update Lists cells and columns however those APIs are currently not ready for public use yet. I will check List team and see if there's plan to open it up for external developers.

Meanwhile @antti-liberis , we do support builtin functions as Add an item to a list , Select a list item , Update a list item, and Delete a list item just FYI

Thanks @cchensh! by builtin functions, do you mean the workflow builder in slack? This is what I'm using at the moment, but without conditional logic I need to create multiple workflows that all do the same but thing for different lists.

In my case, we use lists to track action items and we have separated these by each region we operate in (e.g. US, UK, Nordics etc.)

Currently we have the conditional branching in workflow builder in the pilot phase and it will be available to all users soon. Meanwhile I also filed a request to the Lists team to see if they can expedite the process to expose Lists APIs for public usage.
