how to call a external API when the user clicked on custom web item

[sathish kumar]

I have created a Custom web Item based on some condition which is as below

"issue.issueType?.name == 'Test Execution' && issue.projectObject.key == 'TD'"

and the button is displayed in all issue where the issue type is Test Execution.

I wanted to call some external API and print the status code in the comments when the user is clicked on the custom button

can anyone please help me to achieve this.
