How to Get SprintID for ZAPI calls

Hi,

While trying to execute API calls "Get Execution Summary of the Issues by Sprint", where to get SprintID from the call is like 

POST:"https://prod-api.zephyr4jiracloud.com/connect/public/rest/api/1.0/executions/search/sprint/sprintId/issues".

Also want to confirm, it would be a POST or GET request
