How to Add Comments in Jira Data Center Using the API?

I'm working with Jira Data Center and need to add comments to issues programmatically using the API. I have the necessary permissions and am able to make authenticated requests, but I'm unsure about the correct endpoint and payload format for adding comments.

Here's what I have so far:

API method used: POST request Using Axios:

this.api = axios.create({
    baseURL: 'https://jira-dc-qa.MY-COMPANY-NAME.com/rest/api/2',
    headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${token}`
    }
});

return this.api.request({
    method: 'POST',
    url: `/issue/${issue}/comment`,
    data: {
        body: "example comment"
    }
});

Could someone provide a detailed example of how to properly format the request to add a comment to an issue? Additionally, are there any specific headers or authentication details required?

Code Correction: Ensured the Axios configuration and request options were correctly formatted and included the required data field with the comment body.

Expected Outcome: I expected that with these adjustments, the API call would correctly add a comment to the specified Jira issue, assuming the endpoint, authentication, and permissions are correctly set up.
