1. A method comprising:
receiving, by an authorizing computer from a server computer, an authorization request message in a second message format after mapping data elements of a provisioning request in a first message format to corresponding data elements of the authorization request message in the second message format, the authorization request message provided in response to the server computer receiving an initialization request message in the first message format from a communication device to provision access data, the authorization request message comprising a cryptogram formed using at least a dynamic data element provided by the server computer in response to receiving the initialization request message and a first cryptographic key that is on a user device that provided the cryptogram to the communication device, wherein the first message format is different than the second message format;
validating, by the authorizing computer, the cryptogram using a second cryptographic key on the authorizing computer;
generating, by the authorizing computer, an authorization response message comprising a positive authorization result; and
transmitting, by the authorizing computer to the server computer, the authorization response message comprising the positive authorization result, wherein the server computer provides access data to the communication device in response to receiving the authorization response message and evaluating the positive authorization result.
