Need clarification for Jira products

[Danish Ash]

I would like to know the difference between Jira core vs software vs service desk.

Is there separate APIs for these products or can we use the same jira API for all products.

See https://confluence.atlassian.com/confeval/jira-service-management-evaluator-resources/jira-service-management-the-difference-between-jira-service-management-and-jira-software-core

They all have APIs available at the same place, but because they do different things, they are different calls.
