Environment and methods for enabling electronic transactions

A method, comprising:

• receiving, at a computer system, a request from an application executing on a first computing device associated with a user using a software library of the application provided by a service provider associated with the computer system;
• determining, by the computer system based on the request, a plurality of tokens that each correspond to a particular payment funding source registered to the user, wherein each of the plurality of tokens do not include an underlying identifying primary account number corresponding to a respective payment funding source for that token;
• transmitting, by the computer system, the plurality of tokens to the first computing device;
• receiving, by the computer system, data indicating a selection of a particular token of the plurality of tokens for processing a transaction from the application on the first computing device using the software library;
• generating, by the computer system, a temporary token corresponding to the particular token;
• transmitting, by the computer system, the temporary token to the first computing device;
• receiving, by the computer system, the transaction and the temporary token from a second computing device of a different entity using the software library installed on the second computing device, wherein the different entity is not provided access to the underlying identifying primary account number corresponding to the particular payment funding source for the particular token;
• and
• processing the transaction using the temporary token.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:

• receiving, at a computer system, a request from an application executing on a first computing device associated with a user using a software library of the application provided by a service provider associated with the computer system;
• determining, by the computer system based on the request, a token that corresponds to a payment funding source registered to the user, wherein the token does not include an underlying identifying primary account number corresponding to a payment funding source for that token;
• transmitting, by the computer system, the token to the first computing device;
• receiving, by the computer system, data indicating a selection of the token for processing a transaction from the application on the first computing device using the software library;
• generating, by the computer system, a temporary token corresponding to the token;
• transmitting, by the computer system, the temporary token to the first computing device;
• receiving, by the computer system, the transaction and the temporary token from a second computing device of a different entity using the software library installed on the second computing device, wherein the different entity is not provided access to the underlying identifying primary account number corresponding to the payment funding source for the token;
• and
• processing the transaction using the temporary token.
