Purpose of the incoming REST calls section it take care of the mapping of the data from external systems to JIRA.
It is not always possible or feasible for the other system to talk to JIRA using the native JIRA REST API.
In these cases there is a need for a translation and action based on the format that the external system sends, here is were iHUB shines!
With iHUB incoming three steps process 1. SEND TO IHUB2. IHUB ROUTES IN DATA TO ACTION3. ACTION UPDATES ISSUES ,external systems will be able to create/update JIRA data.
There is a powerful rule engine which can be used to route the incoming request to the correct action.
The action then takes the input from the incoming REST call and sends that to JIRA in the format JIRA expects.
