A method for facilitating provisioning of a token to a token requestor computer, the method comprising: receiving (S602), by a token provider computer , a token request message from a token requestor computer , the token request message comprising an initial access identifier; transmitting (S604), by the token provider computer , the initial access identifier to a first authorization computer ; receiving (S604), by the first authorization computer , the initial access identifier from the token provider computer ; obtaining, by the first authorization computer , an intermediate access identifier based at least in part on the initial access identifier, the intermediate access identifier having a different format to the initial access identifier; storing, by the first authorization computer , a mapping between the initial access identifier and the intermediate access identifier; transmitting (S606), by the first authorization computer , the intermediate access identifier to the token provider computer ; receiving (S606), by the token provider computer , the intermediate access identifier from the first authorization computer ; transmitting (S608), by the token provider computer and based at least in part on the intermediate access identifier, a token activation request message to a second authorization computer ; receiving (S610), by the token provider computer , a token activation response message from the second authorization computer indicating whether the token activation request was approved or denied; and in a case that the token activation request was approved by the second authorization computer, retrieving (S612), by the token provider computer , from a token vault of the token provider computer , the token; storing (S614), by the token provider computer, a mapping between the intermediate access identifier and the token, based on the token activation response message; providing (S618), by the token provider computer, the token to the token requestor computer. receiving (S602), by a token provider computer , a token request message from a token requestor computer , the token request message comprising an initial access identifier; transmitting (S604), by the token provider computer , the initial access identifier to a first authorization computer ; receiving (S604), by the first authorization computer , the initial access identifier from the token provider computer ; obtaining, by the first authorization computer , an intermediate access identifier based at least in part on the initial access identifier, the intermediate access identifier having a different format to the initial access identifier; storing, by the first authorization computer , a mapping between the initial access identifier and the intermediate access identifier; transmitting (S606), by the first authorization computer , the intermediate access identifier to the token provider computer ; receiving (S606), by the token provider computer , the intermediate access identifier from the first authorization computer ; transmitting (S608), by the token provider computer and based at least in part on the intermediate access identifier, a token activation request message to a second authorization computer ; receiving (S610), by the token provider computer , a token activation response message from the second authorization computer indicating whether the token activation request was approved or denied; and in a case that the token activation request was approved by the second authorization computer, retrieving (S612), by the token provider computer , from a token vault of the token provider computer , the token; storing (S614), by the token provider computer, a mapping between the intermediate access identifier and the token, based on the token activation response message; providing (S618), by the token provider computer, the token to the token requestor computer. <EOS>
