I Need help with API ERROR ForbiddenError: Invalid api otp

Hello I wasted the whole day with the API. I can’t get any further where I enter my API keys.
I get this error

Node.js command prompt
c:\gfapi-master>SET GFAPI_KEY=49594010**03a8009###cb7e7c931

c:\gfapi-master>SET GFAPI_SECRET=49594010**03a800###cb7e7c931

c:\gfapi-master>node src\samples\search_listing.js

I don’t know what API_SECRET is so I entered the key there too, I don’t know what else should come in there.
