A system for enabling at least one third-party provider to provide users with access to features of a website (108; 302; 430), the system comprising: a fallback sensor (102; 406), executed by at least one hardware processor (702; 904), to ascertain, for a primary interface (104; 304; 504) that is configured to provide a third-party provider (106; 216; 300; 500) access to the website, at least one metric associated with operation of the primary interface, compare the at least one metric to at least one corresponding metric threshold; based on a determination that the at least one metric exceeds the at least one corresponding metric threshold, generate an indication of a failure associated with the primary interface, and switch the access of the third-party provider to the website from the primary interface to a fallback interface (114; 308; 508), and based on a determination that the at least one metric is less than or equal to the at least one corresponding metric threshold, maintain the access of the third-party provider to the website using the primary interface; and a third-party provider communication implementer, executed by the at least one hardware processor, to control, using the accessed primary interface or the accessed fallback interface, operations between the third-party provider and the website, wherein the third-party provider communication implementer is to implement the primary interface and the fallback interface by: implementing the fallback interface as a controlled Hypertext Transfer Protocol access to a subset of web pages and functionalities of the website; and implementing the primary interface as an application programming interface service layer that is exposed to the third-party provider by a specific integration protocol. a fallback sensor (102; 406), executed by at least one hardware processor (702; 904), to ascertain, for a primary interface (104; 304; 504) that is configured to provide a third-party provider (106; 216; 300; 500) access to the website, at least one metric associated with operation of the primary interface, compare the at least one metric to at least one corresponding metric threshold; based on a determination that the at least one metric exceeds the at least one corresponding metric threshold, generate an indication of a failure associated with the primary interface, and switch the access of the third-party provider to the website from the primary interface to a fallback interface (114; 308; 508), and based on a determination that the at least one metric is less than or equal to the at least one corresponding metric threshold, maintain the access of the third-party provider to the website using the primary interface; and ascertain, for a primary interface (104; 304; 504) that is configured to provide a third-party provider (106; 216; 300; 500) access to the website, at least one metric associated with operation of the primary interface, compare the at least one metric to at least one corresponding metric threshold; based on a determination that the at least one metric exceeds the at least one corresponding metric threshold, generate an indication of a failure associated with the primary interface, and switch the access of the third-party provider to the website from the primary interface to a fallback interface (114; 308; 508), and generate an indication of a failure associated with the primary interface, and switch the access of the third-party provider to the website from the primary interface to a fallback interface (114; 308; 508), and based on a determination that the at least one metric is less than or equal to the at least one corresponding metric threshold, maintain the access of the third-party provider to the website using the primary interface; and a third-party provider communication implementer, executed by the at least one hardware processor, to control, using the accessed primary interface or the accessed fallback interface, operations between the third-party provider and the website, wherein the third-party provider communication implementer is to implement the primary interface and the fallback interface by: implementing the fallback interface as a controlled Hypertext Transfer Protocol access to a subset of web pages and functionalities of the website; and implementing the primary interface as an application programming interface service layer that is exposed to the third-party provider by a specific integration protocol. implementing the fallback interface as a controlled Hypertext Transfer Protocol access to a subset of web pages and functionalities of the website; and implementing the primary interface as an application programming interface service layer that is exposed to the third-party provider by a specific integration protocol.
