Working with lists
Using the Act-On APIs, you can create, update, and merge into lists. For this functionality, you need to know how to get the ID of your newly created list or of any list(s) with which you want to work, and you need to understand how to create and use both uploadSpecs and mergeSpecs.
Any time that you create a new list, the list ID is returned. Once you create a list using POST /api/1/list with uploadspecs (to indicate the headings/system that you need), you can merge your list data using a csv file.
To get the ID for all lists that exist within any Act-On account, use GET list listing (listed in the endpoints table below).
