1. A computer implemented method for retrieving a mapping rule based on a first parameter, wherein the mapping rule enables mapping a first message in a first message format to a second message in a second message format, the second message format being different from the first message format, the method comprising: identifying a first parameter associated with the first message in response to receiving the first message from a first application, wherein the first message format is associated with the first application; identifying a first value of the first parameter; identifying a first variation associated with the first parameter; identifying the mapping rule for the first variation, wherein the mapping rule provides a second variation associated with the first variation; identifying a second parameter associated with the second variation, wherein the second parameter is associated with the second message format; populating the second parameter with the first value; and generating the second message in the second message format based on the second parameter populated with the first value.
