Can I use JIRA Server REST API to interface with Jira Cloud platform?

[assaf.shlomi]

We have integration with the Jira server that uses the Jira Cloud platform REST APIs.

We would like to have the same integration, and this time with the Jira Cloud platform. I understand that the authentication is different. Besides the authentication - are the two APIs compatible or do I need to re-do all the programming work from scratch?

Hi @assaf.shlomi 

Welcome to the Community!!

The API's are different for Cloud, you need to change the endpoints, data formatting of JSON Output

Please find the guide here on REST API's available for Jira Cloud

Let me know if you have any queries

Thanks,

Thanks for the prompt reply. 

I'm aware that there are some changes between the APIs. 

The question is if the Cloud uses a totally new set of APIs or some APIs are still supported. 

We need to understand if we need to re-write the entire integration or we just need to apply some changes, such as new authentication, but the basics will remain (e.g. get issue, update issue, etc.)
