According to an aspect of an embodiment, operations include receiving a first input corresponding to a selection of one or more Application Programming Interface (API)-based trigger options associated with one or more electronic trigger events. The operations further include receiving a second input corresponding to a selection of one or more trigger rules which are applicable on event data associated with the one or more electronic trigger events and receiving a third input corresponding to a selection of one or more API-based actions. The operations further include constructing an API mashup template based on the first input, the second input, and the third input and generating an API mashup code based on the constructed API mashup template. The API mashup code is configured to be computer-executable on a runtime system.
