Automatic interactive element visualizations in connection with server operation

A system for background communication with a foreign programming interface to receive a concurrent interactive element, the system comprising:

• at least one computer including one or more processors and a memory, wherein the one or more processors execute:
• a web browser plugin configured to execute within a web browser of a computing device to:
• receive viewing instructions stored on a server and configured to present a viewed item;
• determine that the viewed item is eligible for an instalment contract and that the viewing instructions include an indication of a viewed item identifier (ID), wherein the viewed item ID is one of a plurality of viewed item IDs, wherein each viewed item ID of the plurality of viewed item IDs uniquely identifies a respective item of a plurality of items including the viewed item;
• communicate, to a second server, an indication of the viewed item ID automatically in response to executing the viewing instructions to present the viewed item in a graphical user interface (GUI) on a display associated with the computing device;
• and
• receive a representation of an interactive element that is associated with a concurrent item that is identified based on the viewed item, wherein the interactive element comprises an indication of a storage location of another server;
• and
• a second server application programming interface (API) configured to:
• receive, from the plugin, the indication of the viewed item ID;
• compare, in response to receiving the indication of the viewed item ID, the indication of the viewed item ID with a plurality of potential items represented by an item storehouse, wherein each potential item is associated with a potential interactive element;
• receive, from the storage location of the another server, the concurrent item from the plurality of potential items that is associated with the viewed item and an interactive element that is associated with the concurrent item, the interactive element indicative of an executable element and at least one of a total amount, a term, or a term amount;
• modify one or more instructions of the executable element;
• and
• transmit, to the plugin, the modified one or more instructions of the executable element,
• wherein the plugin is further configured to:
• receive the modified one or more instructions of the executable element;
• execute the modified one or more instructions of the executable element to generate the interactive element and the at least one of the total amount, the term, or the term amount;
• present, via the GUI on the display and in association with the viewed item, the interactive element and the at least one of the total amount, the term, or the term amount;
• receive, via the interactive element in the GUI, input modifying at least one of the total amount, the term, or the term amount;
• and
• automatically communicate, to the second server API based on the input, indications of the modified at least one of the total amount, the term, or the term amount, wherein the second server API is configured to:
• based on the indications of the modified at least one of the total amount, the term, or the term amount, further modify the instructions of the executable element to generate further modified instructions of the executable element;
• and
• transmit, to the plugin, the further modified one or more instructions of the executable element,
• wherein the plugin is further configured to:
• execute the further modified instructions of the executable element to render the GUI on the display in real-time to include the modified at least one of the total amount, the term, or the term amount as a customized offer.
