How to avoid duplicate ticket creation raised through API in JIRA cloud Service Desk

[Sateesh Dara]

We have a Service Desk project and Tickets get created through API whenever a user submits feedback in our online app.

Somehow for each feedback, two tickets(One is an exact duplicate with time also) are getting created exactly at the same time stamp.

See the screenshot attached.

Not able to understand where the problem is. The developer who has configured integration of APP-JIRA confirms "that ticket creation through API to JIRA code/flow is all fine, no changes can be done from his side as his settings or code is fine"

How to get rid of these duplicates and create only one ticket for each feedback provided by the User?

Please suggest.
