Need Help Setting Up OpenBullet API URL and API Key – Any Tips?

Yo, thanks for all the tips, y’all! I tried using Postman like someone suggested, and it turns out I was missing a required header in the request. Also, the API key was case-sensitive, which I didn’t realize. Still, I’m getting a 403 error now—any idea what that’s about? Is it a permissions thing, or could it be something else? Appreciate the help, tho!
