A system for provisioning services, comprising:

• a provisioning server executing a provisioning application;
• an adapter software component embodied within the provisioning server;
• and
• a provisioning application programming interface (API), embodied within the provisioning server, in communication with the provisioning application and said adapter software component, the provisioning API comprising:
• discovery transactions that allow said adapter software component to retrieve information regarding services available to a client device from a provisioning application, wherein the provisioning application includes client device information for each client device the provisioning application services, wherein a service comprises a plurality of content files capable of being installed on the client device;
• subscription transactions that allow an adapter software component to manage content in service directories, wherein a service directory comprises a plurality of services;
• and
• delivery transactions that allow an adapter to facilitate downloading of data related to services to the client device, with the delivery transactions including an update transaction that allows said adapter to obtain a provisioning update comprising a list of services that should be installed on the client device, the delivery transactions further including a notification transaction that allows the provisioning application to request an adapter to perform an update transaction, and wherein the delivery transactions further include a delivery transaction that allows said adapter to obtain a link to data, the link facilitating downloading of the data.
