Getting column ID and column value from my automation block

Hello!

With the deprecation of “Integration for sentence builder”, I need to migrate my existing workflow blocks to the new automation blocks. I’m struggling to reproduce the same behavior.

My current, working sentence builder action works like this:

When column changes → user selects the relevant column → user selects my action → user maps the fields.

For example:

When Registration changes → then set vehicle brand in >brand column<

When the automation runs, monday sends the following parameters to my Run URL:

• boardId
• itemId
• columnId — the selected Registration column
• columnValue — the actual Registration value
• brandColumnId — the column where I should write the brand

Using these parameters, I can update the item through the GraphQL API.

Below are the input fields from my old sentence builder action:

With the new automation blocks, I tried to recreate the same behavior: the user enters a license plate/registration, and the automation communicates with my Run URL so I can set the vehicle brand.

However, I can’t figure out how to get the columnId and columnValue from the column selected in “When column changes”. I only receive:

• boardId
• itemId
• brandColumnId

I’ve tried several approaches, but they have led to different issues, such as:

• the automation not being saveable,
• the automation block not appearing at all,
• or strange behavior in the automation builder.

Below are the input fields from my new automation block:

Has anyone successfully migrated this kind of workflow from sentence builder actions to automation blocks?

Specifically, I’m trying to understand:

1. How can I access the column ID of the column selected in “When column changes”?
2. How can I access the changed column value and pass it to my Run URL?
3. Is there a recommended way to model this in the new automation block structure?

Any help would be greatly appreciated — I’m a bit stuck here.
