Delivery of instructions in host applications

Non-transitory physical computer storage comprising instructions stored thereon for implementing, in one or more computer hardware processors, a method comprising:

• executing a host application comprising a first tag library, the first tag library configured to track interaction data indicative of end user interactions with a physical user computing device;
• sending a request to a first remote network server;
• receiving, from the first remote network server, a response to the request, the response comprising a token;
• sending the token to a second remote network server;
• receiving, from the second remote network server, a second tag library comprising application logic, wherein the application logic comprises the token;
• executing the host application to generate an event indicating a user interaction with the physical user computing device;
• loading, in the host application, the application logic comprising a set of instructions;
• determining, using the application logic, to track the event;
• and
• executing the set of instructions specified by the application logic to cause the physical user computing device to transmit first data associated with the event, wherein the first data comprises the token.

A system comprising:

• non-transitory physical computer storage configured to store a host application comprising a first tag library, the first tag library configured to track interaction data indicative of end user interactions with a physical user computing device;
• and
• a computer hardware processor in the physical user computing device, the computer hardware processor being in communication with the non-transitory physical computer storage and configured to:
• execute the host application;
• send a request to a first remote network server;
• receive, from the first remote network server, a response to the request, the response comprising a token;
• send the token to a second remote network server;
• receive, from the second remote network server, a second tag library comprising application logic, wherein the application logic comprises the token;
• execute the host application to generate an event indicating a user interaction with the physical user computing device;
• load, in the host application, the application logic comprising a set of instructions;
• determine, using the application logic, to track the event;
• and
• execute the set of instructions specified by the application logic to cause the physical user computing device to transmit first data associated with the event, wherein the first data comprises the token.
