Hi,

I have to dynamically update a subscription according to some criteria in a contact record.
E.g. In a contact record, we store sales figures. If the last sales figues is less than an amount, I want to add a discount line in the customer's subscription. Next month, if the sales figues is more than an amount, I want to remove this line.

I think it should be possible with a scheduled action which will be executed 1 time / month. Each time, we check the contact sales figues and process the action to add / remove a subscription line. 

I just don't know the Python code to add / remove lines in a subscription through a scheduled action.

Thanks for assistance.
