Update tables via services

Is it now possible to update a table via a service?

Background: I have a table that I use for communication, similar to a chat history. Now, the data should be updated back and forth between two teams by exchanging the chat history between two forms.

The first transfer to another form works because I am "creating" the record. However, in the other direction, the data needs to be "updated," but I don't have an option to select the table.

How can I accomplish this? Or is there a better way to implement it?

You can update table information using our REST API but not using a Service Configuration within a Leap app/form.

If it were me, I would have all that information in a different form. Each time a user wants to send a message you would create a new record. When you render the form you call a search service to display all the records (but you would clear the table before submitting because it is only for display and not the "source" of the data).

The form can be in the same app.

Happy to discuss further if needed.
