Completely lost implementing an embedded mind map API

Need help APIs
1

I’m trying to embed a mindmeister mind map to my website using their embed API found here. I’ve been following this YouTube tutorial but when I try to initialize the call I get a 401 issue as my API key is non existent or invalid, this is likely due to me messing up something else in my get or headers as my key is showing up as active on the mindmeister site. Any help or links to useful resources would be appreciated. Screenshot of my current inputs with my api key hidden is included below.

Have you tried to see if you’re able to initialize as a parameter instead of a header?
