List Types

• EMAIL (default): Standard subscriber list. Each email address must be unique — a subscriber can only appear once.
• CRM: CRM-type list. Each email address must be unique — a subscriber can only appear once.
• ORDER: Order/e-commerce list. The same email address can appear multiple times, as each row represents a separate order.

• Pass 0 to place the list in the root (default) folder.
• Pass a valid project folder ID to place the list in a specific folder. The folder must belong to the authenticated account.

Default Behavior

• List type defaults to EMAIL if not specified.
• Language defaults to hu (Hungarian) if not specified.
• Currency defaults to HUF if not specified.
