Integrated backend and dynamic interface system for handling multiple transaction channels across different devices

A non-transitory computer-readable medium comprising program code that is executable by one or more processors of a client device of a user for causing the client device to perform operations, the operations including:

• providing a channel identifier to a backend server system indicating a transaction channel associated with the client device, wherein the channel identifier uniquely identifies one of a plurality of transaction channels, wherein each transaction channel of the plurality of transaction channels is a different type of modality through which a plurality of client devices can submit object orders to the backend server system, and wherein the backend server system is configured to:
• determine, based on the channel identifier, that the transaction channel is associated with the client device;
• and
• based on determining that the transaction channel is associated with the client device, determine one or more graphical features to include in a first graphical user interface based on the transaction channel;
• outputting the first graphical user interface with the one or more graphical features determined by the backend server system;
• subsequent to outputting the first graphical user interface, receiving a unique identification code corresponding to a customer of an entity, the unique identification code being different than the channel identifier;
• forwarding the unique identification code to the backend server system, the backend server system being configured to analyze a history of the customer to determine a customized object previously obtained by the customer from the entity;
• receiving information from the backend server system about the customized object previously obtained by the customer from the entity;
• displaying a second graphical user interface indicating the customized object associated with the customer in addition to the one or more graphical features determined by the backend server system;
• receiving a selection by the user of a graphical option associated with the customized object;
• in response to receiving the selection from the user, adding the customized object to an object order for the customer;
• and
• in response to detecting a transaction completion for the customer, reverting to displaying the first graphical user interface;
• wherein the backend server system is further configured to:
• in response to determining that a rule change did not occur within a first time window:
• identify a previous order that also includes the customized object;
• based on identifying the previous order, determine variable information associated with the previous order by receiving the variable information from a database that is separate from a remote system, wherein the variable information is different than the customized object;
• and
• based on receiving the variable information from the database, forego communicating with the remote system to determine the variable information;
• and
• in response to determining that the rule change occurred within a second time window that is different from the first time window, determine the variable information related to the customized object by communicating with the remote system;
• and
• apply the variable information to the object order.

A client device comprising:

• one or more processors;
• and
• one or more memories including instructions that are executable by the one or more processors for causing the one or more processors to perform operations, the operations including:
• providing a channel identifier to a backend server system indicating a transaction channel associated with the client device, wherein the channel identifier uniquely identifies one of a plurality of transaction channels, wherein each transaction channel of the plurality of transaction channels is a different type of modality through which a plurality of client devices can submit object orders to the backend server system, and wherein the backend server system is configured to:
• determine, based on the channel identifier, that the transaction channel is associated with the client device;
• and
• based on determining that the transaction channel is associated with the client device, determine one or more graphical features to include in a first graphical user interface based on the transaction channel;
• outputting the first graphical user interface with the one or more graphical features determined by the backend server system;
• subsequent to outputting the first graphical user interface, receiving a unique identification code corresponding to a customer at a physical location associated with an entity, the customer being different than a user of the client device, and the unique identification code being different from the channel identifier;
• providing the unique identification code to the backend server system that is remote from the physical location, the backend server system being configured to analyze a history of the customer to determine a customized object previously obtained by the customer from the entity;
• receiving information about the customized object previously obtained by the customer from the entity;
• displaying the a second graphical user interface indicating the customized object associated with the customer in addition to the one or more graphical features determined by the backend server system;
• receiving a selection by the user of a graphical option associated with the customized object;
• in response to receiving the selection from the user, adding the customized object to an object order for the customer;
• and
• in response to detecting a transaction completion for the customer, reverting to displaying the first graphical user interface;
• wherein the backend server system is further configured to:
• in response to determining that a rule change did not occur within a first time window:
• identify a previous order that also includes the customized object;
• based on identifying the previous order, determine variable information associated with the previous order by receiving the variable information from a database that is separate from a remote system, wherein the variable information is different than the customized object;
• and
• based on receiving the variable information from the database, forego communicating with the remote system to determine the variable information;
• and
• in response to determining that the rule change occurred within a second time window that is different from the first time window, determine the variable information related to the customized object by communicating with the remote system;
• and
• apply the variable information to the object order.
