Method and system for authorizing long-lived transactions

A system for authorizing a transaction, the system comprising:

• an interface frontend device of a hosted service;
• an interface backend device of the hosted service;
• and
• a non-transitory computer-readable storage medium in communication with a storage device, wherein the computer-readable storage medium comprises one or more programming instructions that, when executed by a computing device, will:
• cause the interface frontend device to receive, from a client device, a request to access an account,
• cause the interface backend device to determine that a user of the client device is permitted to access the account, and
• in response to determining that the user is permitted to access the account, cause the hosted service to:
• initiate an account session and generate a login credential that includes an indication that the user is logged into the account,
• receive, from the client device, a request to initiate a transaction,
• determine that the transaction is a long-lived transaction,
• in response to determining that the transaction is a long-lived transaction, create a transaction credential associated with the long-lived transaction,
• determine that the account session has expired,
• update the login credential to include an indication that the user is not logged into the account,
• determine, based at least in part on the transaction credential, that the execution of the long-lived transaction is authorized after expiration of the account session, and
• in response to determining that execution of the long-lived transaction is authorized after expiration of the account session, cause the hosted service to allow the long-lived transaction to execute after the account session has expired.
