date filter on REST API

[Michele Baronchelli (AB)]

I'm using the new REST API to get all the issues for a project, but I need to filter the ones updetad after a certain date. 

I tried with JQL query, specifically ".../search/jql?jql=project=xxxx&updated>2025-09-12" but it gives me back all the tickets and not the ones updated after 12/09/2025.

I've tried with various formats like dd/MM/yyyy, MM/dd/yyyy or yyyy-MM-ddTHH:mm:ss.ffff but nothing works. How do I have to use this otions with the new API? With the old one it worked well with the datetime format yyyy-MM-dd

Thanks

The reason is that your JQL query is invalid.

If you refer to the JQL documentation, you will learn that the keyword for joining functions is 'AND' not an ampersand '&', so your JQL query should be:

"project=xxxx AND updated>2025-09-12"
