Rename the 'Name' column using the API from 'Item'?

I don’t think that’s part of the public API, so not possible without using the monday UI.

The exact call in the browser sends the equivalent of this curl:

curl 'https://myslug.monday.com/boards/1234' \\
  -X 'PUT' \\
  -H 'X-CSRF-Token: *****' \\
  ...
  -H 'Accept: application/json, text/javascript, */*; q=0.01' \\
  -H 'Content-Type: application/json' \\
  -H 'X-SOURCE-PRODUCT-KIND: core' \\
  --data-raw '{"pulse_nickname":{"preset_type":"other","singular":"My custom name","plural":"My custom names"},"caller":"set-pulse-nickname-component"}'  

Also, asking “Ask AI” I get:

Is there a way to Change item terminology using graphql?

I’m sorry, but the knowledge sources do not contain any information about changing the item terminology (nickname for items on a board) using GraphQL or the monday.com API. The item_terminology field is available as a read-only field when querying board details, but there is no documented mutation or API method to update it programmatically Api-reference > Reference > Boards}(Boards).

If you need to change the item terminology, you will likely need to do so manually through the monday.com web interface.

I believe you can use this mutation:

mutation {
  change_multiple_column_values(item_id:9876543210, board_id:1234567890, column_values: "{\"name\" : \"My Item\"}") {
    id
  }
}

​@hellotimi This is about changing the title of the column from, say “Item” to “Contact”, not the value contained inside the name.

It isnt really supported programmatically but can be changed from the UI. You can choose a custom name and then template the board so you dont need to set it each time.
