To use Pivotal Tracker integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a generic authentication method. Once connected, you can make custom API calls to Pivotal Tracker to query the data you need using the URLs you provide, for example:
after authenticating the HTTP Request node, you can create a new story in Pivotal Tracker by sending a POST request to the /projects/{project_id}/stories endpoint with the appropriate payload.
For retrieving existing stories, use a GET request to the /projects/{project_id}/stories endpoint with any query parameters specified.
To update a story, send a PUT request to /stories/{story_id} with the updated data in the body.
