The KickoffLabs viral referral API allows users to build a viral referral (sharing) solution. The API offers developers the ability to customize landing pages as well. Lastly, a developer can make an existing page more viral.
The API consists of two end points. Using these two end points, developers can create a subscription by email address, set their social share id, control if they get the autoresponder email, and return info about previous subscriptions. This API uses HTTP calls and responses are formatted in JSON.
