[jai shree ram]

How to get all sprints started from last 2 months & number of stories or task added & removed from each sprints.

Also is there any API to find  or get the spilled over stories?

API or jql is also fine.

 To get all sprints started from last 2 months, I can do this like below 

First get  all the board for given project 

https://jira.rakuten-it.com/jira/rest/agile/latest/board?projectKeyOrId=WMSIND

now get the sprint details for given board

https://jira.rakuten-it.com/jira/rest/agile/latest/board/{boardId}/sprint

but how to add to get only those sprint whose start date is greater than last 2 month?

And Also how to know how many stories or task is added and deleted for given sprint or each sprint.
