An Acquisition Campaign defines a keyword or keywords, and/or API methods that you can use to opt into a Mobile Database list. It is an interactive SMS texting campaign that you can link to your Broadcast Campaign to allow consumers to text in a keyword to sign up for a Subscription List. The Acquisition Campaign can only point to one Broadcast List at a time, but you can have more than one Acquisition Campaign pointing to the same Broadcast List if you'd like.
The Acquisition APIs are used to add or search for Participants, and Get Acquisitions Campaigns.
The Callbacks are triggered when a Participant is added, or their status has changed.
