Hi Ronaldo, I'm going to quote an answer (with a bit of updates to direct at this question) from a previous answerer as that person has given a very good description and brief guide on how to use Jira's REST API: * Get the total issues in a project with a basic and 'quick and light' query* URL: https:///rest/api/2/search?jql=project= * This gives a result like --> { "startAt": 0, "maxResults": 50, "total": 24, "issues": [...] } * Iterate over the total number of issues to fetch the desired details/fields of each issue.* Note: Maximum allowable fetch seems to be 1000 issues at a time. * We can also filter the fields that we are interested to fetch. Since you are only interested in key, we will filter fields shown to just key. * search on URL: "https:///rest/api/2/search?jql=project=&fields=key" I highly suggest reading the previous answerer's post as it will give you more context and has some other useful tips to handle projects with > 1000 issues - sayeed1310's answer
