accessing, from the user account data associated with the user account, a first one or more authorization parameters associated with the one or more authorization transactions through the at least an API associated with the institution and using the account credentials; and

comparing the first one or more authorization parameters with a second one or more authorization parameters associated with the one or more authorization transactions to determine that the first one or more authorization parameters and the second one or more authorization parameters match, wherein the second one or more authorization parameters are stored by the computer system upon initiating the one or more authorization transactions.

11. The computer system of claim 10 , wherein the one or more processors are configured to execute the program instructions to further cause the computer system to:

in response to initiating the one or more authorization transactions, and before verifying the one or more authorization transactions, generate an interim token.

12. The computer system of claim 1 , wherein the one or more processors are configured to execute the program instructions to further cause the computer system to:

in response to determining that at least one of: the institution does not support the second fallback authorization mechanism, or the second fallback authorization mechanism failed:

initiate a third fallback authorization mechanism;

if not already initiated, initiate one or more authorization transactions to the user account using the first account identifier and the institution identifier associated with the institution;

receive a first one or more authorization parameters from the computing device operated by the user; and
