How can I programmatically insert a comment into a Jira Data Center issue using the API?

Post a comment on a Jira Data Center issue using the API.

const client = axios.create({
  baseURL: 'https://jira-dc.example.com/api',
  headers: { 'Authorization': 'Token Z' }
});
client.post('/issue/ID/comment', { text: 'Hi' });

I have integrated the Jira Data Center API into a few projects and can share that while the approach shown is sound, it’s useful to double-check your Jira version’s documentation to ensure that the endpoint structure is correct. There have been times when slight modifications were needed to match the API version in use, and error handling was crucial for troubleshooting. Also, logging both request and response details has helped me identify misconfigurations early. I recommend testing your API calls in a development environment before deploying any automation scripts.

In my experience with Jira Data Center, ensuring that the authentication and headers are correctly set up is key when inserting comments programmatically. I once encountered issues where additional parameters were required on some endpoints, so I made sure to cross-check the API documentation frequently for any discrepancies due to version upgrades. Thorough logging and error analysis during the development phase helped me address unexpected responses quickly. Additionally, verifying that the base URL corresponds accurately to the instance environment has saved me from many potential misconfigurations in production.
