From what I understand, it happens when there’s a mismatch with the current state of the resource, but I’m not sure how to deal with it effectively on both the client and server sides.</P> <P>I found this <A href="https://www.resultfirst.com/blog/http-status-code/409-status-code/" target="_self">blog</A> that breaks down the causes and solutions for this error. It looks useful, but some parts were a bit hard to follow for me.</P> <P>If anyone has experience with resolving this, could you share some examples? For instance, how do you handle things like optimistic locking or retries?</P> Mon, 06 Jan 2025 12:33:03 GMT davissmith 2025-01-06T12:33:03Z https://community.qlik.com/t5/Talend-Studio/How-to-handle-409-Conflict-error-in-a-RESTful-API-gracefully/m-p/2500103#M143270 <P>Hi,</P> <P>I’m facing a problem with a 409 Conflict error in my RESTful API, especially when updating resources or handling concurrent requests.
