We need to bring the history of changes done to a custom field in Jira with the help of REST API. Please advise.

Hello @Bhavani Mahesh Bhrugubanda 

Are you trying to get the history of changes of values for a custom field in issues, or are you trying get changes to the configuration of the field like Context definitions?

When you use the issue endpoint  with an issue key you can use the expand parameter to get the entire change log for the issue. You would need to parse through that information to get the entries relevant to the custom field.
