I am getting 400 Error, while creating a contact list?
Is there any sample code available for creating a list.
Creating a new list in your account involves doing an HTTP post of the proper XML to the lists collection. If you are looking for sample XML to create a contact list, I would recommend taking a look at Creating a New List. This will give you an example of the XML that would be required to create a contact list. I hope that this helps. Please let us know if you have any other questions.
