I couldn't find a public API for getting Logsnag data, so I wrote a scraper. Love the product, but wtf why is the data vendor locked?
git clone this codebase, and inspect the fetch requests on app.logsnag.com to get your projectId and Authorization token to use this.
Declare them in a .env file:
PROJECT_ID=
AUTHORIZATION=
Then run npm i and node index.js
If you run into any other issues, try copying the entire fetch request from the browser tools and replace all headers and context in the mock request in index.js with that.
